Offers New Magnetic Couplings
Magnetic couplings from Miki Pulley are ideal for machine designs involving food, pharmaceutical and laboratory applications requiring clean, non-contact connection between motor and shafts.
The mechanically isolated magnetic coupling transmits torque through the air. This occurs through both input and output hubs of the coupling which contain powerful rare-earth neodymium magnets. These magnets create a magnetic field that transmits torque through plastic, glass, aluminum, and other minimally ferrous materials without physical engagement.
Miki Pulleyâ€™s Magnetic Couplingâ€™s non-contact design is particularly important where cleanliness and motor isolation is required in the mixing system design. The coupling is clean and operates with no vibration. There is no dust, debris or mechanical wear using this coupling compared to conventional couplings. Also important, this coupling has a â€śsofterâ€ť start/stop function compared to conventional, general-purpose couplings. In addition to mechanically isolating the connecting shafts and motor, the coupling also isolates thermal and electrical occurrences.
These magnetic couplings have an intended engineered torque limit at a specific air gap. The transmittable maximum torque may be adjusted by increasing/decreasing distance between coupling hubs. Depending on model, size, and installed air-gap, the magnetic couplingsâ€™ maximum torque limit may be exceeded without mechanical damage. The hub simply slips to the next magnetic pole, without noise or mechanical wear.
While the magnetic field between the two hubs will transmit rotational force, it can also act as a torque limiter in an over-load event. The transmittable-torque and slip-torque may be metered by adjusting the distance between the hubs. After slipping, the hubs will re-engage each other and continue to transmit torque. This feature produces no mechanical wear on components.
Miki Pulley Magnetic Couplings are available in different configurations including shaft-to-shaft, parallel cylinder, perpendicular and well as stainless and plastic clad versions for food/washdown environments.
Provides Software Solutions for Solar Race Car
Siemens Digital Industries Software is sponsoring Team Sonnenwagen Aachenâ€“ a German student initiative focused on developing new sustainable mobility conceptsâ€‰â€”â€‰in the design and development process of the Sonnenwagen 3 solar race car. Sonnenwagen leverages Siemensâ€™ Teamcenter software to address their challenge of coordinating and optimizing the interdependent areas of aerodynamics, mechanical and electrical systems, and vehicle structure on a tight schedule. By streamlining the exchange between NX software and Simcenter software including Simcenter STAR-CCM+ software and Simcenter Amesim software, Teamcenter allows Sonnenwagen to exchange design models across applications more easily and efficiently.
Sonnenwagen is using Teamcenter, a tool within Siemensâ€™ Xcelerator portfolio of integrated software and services, to speed up their design process and limit the additional need for planning and coordination. Designing a solar car like the Sonnenwagen 3 requires a team to handle many different parts that need to be integrated into the main assembly. By using Teamcenter as a data management tool, Sonnenwagen has been able to accelerate iteration loops and design a better Sonnenwagen 3.
â€śIn past product development phases, we regularly ran into issues transferring models and data between different software solutions. This slows our designing process down and creates an additional need for planning and coordination,â€ť says Simon Quinker, vice chairman and head of marketing at Team Sonnenwagen. â€śThe pivotal point of our development came from Teamcenter. In addition to software, Siemens has been very supportive with their know-how expertise and helped us overcome hurdles and get the best out of the software.â€ť
Sonnenwagen has benefitted largely from the highly integrated software portfolio in combination with powerful simulation tools. Siemensâ€™ NX software allowed Sonnenwagen to design a new outer shell of the Sonnenwagen 3 solar car, where they were able to transfer it to Simcenter STAR CCM+ and assess its aerodynamic efficiency. With Teamcenter allowing for efficient exchange of models across applications, the team can then take those results back to Siemensâ€™ NX software to optimize the design and initiate the iteration loop once again. Additionally, by utilizing Siemens Amesim, the team can quickly simulate components designed in NX according to their functionality and use the results for the optimization of the component in NX.
â€śWe are very pleased with the developments Sonnenwagen has been able to make by utilizing Siemensâ€™ software solutions as a whole,â€ť said Naz Aydemir, academic business development consultant for Siemens Digital Industries Software. â€śBy working closely with the Siemens software product family throughout the development process, itâ€™s great to see the Sonnenwagen overcome challenges and allow us as a proud sponsor to offer solutions that they can benefit from.â€ť
Announces Release of KIZEI Spherical Roller Bearings
NTN Bearing Corporation of America is pleased to announce the release of its latest innovation, the KIZEI (pronounced kee-zee) spherical roller bearing. KIZEI spherical roller bearings, developed by the NTN-SNR team in Annecy, France, are the first spherical roller bearings with metallic shields that protect the bearing from solid contamination such as dust, pebbles, and other debris.
In Japan, â€śKiseiâ€ť with an â€śsâ€ť, means â€śregulationâ€ť. Since the shields on the bearing â€śregulateâ€ť how much contamination is going in and how much grease is going out, it made for a fitting name. However, we switched out the â€śSâ€ť for a â€śZâ€ť because in bearing part number terminology, metal shields, like those used in this new series, are commonly symbolized by a â€śZâ€ť suffixâ€“hence the name KIZEI. A â€śZZâ€ť suffix is added to the standard ULTAGE part number to identify a shield on both sides of the KIZEI series.
â€śWe are thrilled to be able to offer our customers the newest of our cutting-edge solutions,â€ť exclaimed James Misch, Director of Marketing and Technical Services, NTN. â€śOver the last four years, KIZEI spherical roller bearings have undergone extensive research, development, and real-world testing to get to this point, and we are pleased to finally be able to offer this revolutionary product to our customers at large.â€ť
The unique design of KIZEI spherical roller bearings incorporates the metallic shields with the bearing retainer to form a one-piece protective barrier to keep contaminants out. Additionally, the metallic shields improve grease retention which helps improve bearing life.
In addition to the integration of the metallic shields into the design, KIZEI products also maintain the new standards set forth by NTNâ€™s ULTAGEÂ® spherical roller bearings. Featuring the industryâ€™s highest speed and load ratings, as well as wide operating temperatures, ULTAGE is the newest generation of high-performance bearings from NTN and is the new standard in its spherical roller bearing offering.
Furthermore, KIZEI products come in standard ISO dimensions, ensuring interchangeability with 22200 series spherical roller bearings. Unlike the larger sealed spherical roller bearing models that require special tools & accessories for installation, KIZEI utilizes the same mechanisms used with standard open bearingsâ€‰â€”â€‰housing, accessories, mounting, grease, etc.â€‰â€”â€‰reducing maintenances costs.
NTNâ€™s KIZEI spherical roller bearings have been proven to provide superior performance in demanding industries such as mining, metals manufacturing, wood processing, aggregate, cement, infrastructure, and construction.
Additional information on KIZEI spherical roller bearings can be found on Bearing Finder. Designed to aid distributors, design engineers, and end users in finding the perfect bearing or related product to use in any application, Bearing Finder is hosted on a proprietary platform that offers a customizable part search tool, interactive and downloadable CAD illustrations, comprehensive part interchanges, and exhaustive data sets.
Encoders Provide Consistency for Metrology Designs in Machining
With the release of new MULTI Degrees-of-Freedom (MULTI-DOF) encoders, Heidenhain offers machine manufacturers a better way to implement metrology designs to obtain multiple measurements simultaneously and facilitate correcting deviations on the fly. Conventional encoders offer one degree of motion, but these three new encoders do more to serve the demanding requirements of machines in the semiconductor and electronics industry, among others. They include the new LIP 6031 Dplus, the GAP 1081 and the MKV 1/9Ă—30.
Traditionally, an encoder is only able to measure deviations along a single axis and although these can be corrected via some controllers, they can still be blind to common but unavoidable effects of guideway error or thermal linear expansion (to name a few) which would cause deflection along multiple axes. Using multiple reader heads allows for the detection of these deflections as in these new products, allowing for the necessary compensation at the inception and ensuring the integrity of the machine.
Users of these high accuracy MULTI-DOF encoders can expect high reproducibility and consistent quality in their systems.

Continues Advancing Industrial Ethernet Communications
Time-Sensitive Networking (TSN) is paving the way for industrial Ethernet to support the industrial communications needs of the future by providing innovative, highly beneficial functionalities. Companies are well aware of this potential, with multiple key developments happening to fully realize TSN-driven digital manufacturing strategies.
Arno Stock, Business Development Manager at CC-Link Partner Association (CLPA) member Renesas Electronics, looks at what TSN can offer and the latest achievements that are shaping the future of industrial Ethernet.
TSN is an extremely promising technology that will allow industrial Ethernet to reach new levels. Operating at Layer 2 of the Open Systems Interconnection (OSI) model, it enhances standard Ethernet as we know it by making it deterministic by design. This characteristic, in turn, will benefit end users in a variety of industries by offering the ability to merge different types of data traffic, leading to more flexible and collaborative environments. At the same time, this creates simplified, more economical network architectures as well as unified hardware and software systems.
Therefore, the crucial role of TSN in futureproof, digital manufacturing is clear. This technology is the precondition needed to support key Industry 4.0 applications and trends, such as Edge and Cloud computing.
A smooth transition
In addition to these most obvious advantages, an instrumental feature of TSN is its continuity with existing network technology. In effect, while it offers unprecedented capabilities, it does so by evolving conventional Ethernet rather than by substantially disrupting the status quo. As a result, businesses can seamlessly transition towards TSN-compatible industrial Ethernet systems.
This also means that TSN is compatible with legacy standards. Furthermore, it can be combined with additional solutions that are already available for conventional industrial Ethernet, such as gigabit bandwidth, which is key to support ever-increasing data throughput. In addition, it can accommodate the higher number of network devices and nodes resulting from converged architectures.
Additional advantages of mixing TSN and gigabit Ethernet include the ability to shorten cycle times, increase the accuracy and precision of control loops as well as strengthening the ability of a network to transfer various types of data, such as video. Such a solution can also reduce the complexity of distributed control systems, as it is possible to reliably move more functions to a single controller, also making the intended applications more robust as well as easier to set up and maintain.
End users are ready for TSN
The multiple benefits of TSN are evident to machine builders and end users. In particular, Renesas is noticing a high level of interest from its customers, who are aware the technology will be a must in the years to come. A key aspect that is extremely appealing to most of them is the standardization/simplification of protocols, enabling the connection of all parts within an enterprise.
In order to successfully implement TSN, it is necessary to use a network technology with higher-level protocols, as these are needed to complete the OSI reference model and support TSN applications. An example is the open industrial Ethernet CC-Link IE TSN. In addition, companies require suitable hardware that can utilize this Layer 2 technology, such as Renesasâ€™ R-IN32M4-CL3 large scale integration (LSI) that leverages CC-Link IE TSN. Driver-level support is also important, as real-time TSN-compatible systems require a close interaction between low-level driver software and hardware equipment.
To address these aspects with leading solutions, automation vendors need to team up to deliver devices with TSN capabilities that meet customersâ€™ expectations and needs. Being part of an extensive partnership network, such as the CLPA, is thus extremely beneficial, as it offers a forum where solution providers come together to drive the development and consolidation of key automation products.
A look at the future of industrial communications
A number of major milestones have been reached to support the use of TSN. In particular, the IEEE 802.1 standards defining the technology are now complete and accessible. Also, the first network solutions have been released to the market, namely CC-Link IE TSNâ€‰â€”â€‰the first open Ethernet that combines gigabit bandwidth and TSN capabilities.
Finally, the first prototypes and complete products have already appeared, with actual devices available and ready for use now. More testbeds are also ongoing or planned to take place in the short term. These contribute to making the technology more mature and support its large-scale implementation.
The sector is working towards the finalization of IEEE profiles, particularly for industrial automation as well as the development of new applications for wider use, not confined solely to industrial settings. To support the global adoption of TSN, it will soon be essential to set up unified conformance testing to make sure that different solutions are interoperable, hence truly leveraging the full potential of TSN. Open technologies, such as CC-Link IE TSN, are therefore likely to be favored.
The transition towards TSN will be particularly exciting, as it is a natural evolution of Ethernet that will support its continuous improvement. Ultimately, we will be able to benefit from more and more building blocks that will open up new functions and higher performance while supporting existing, still functioning systems.
