Electromechanical rodless linear actuators can offer better load handling in smaller spaces than rod-style actuators, but realizing those benefits requires careful attention at the specification level. Whether you are replacing a failed actuator, looking for better performance or building a new application from the ground up, success depends on how precisely you specify application requirements.
When it comes to specifying linear motion within a machine, system designers have many options from which to choose. Making the right choice can impact the ease of installation, footprint and cost of operation.
The following article is a round-up of the latest linear motion product and industry news items featured at www.powertransmission.com and on social media.
The Swiss Army Knife of PT Components.
Here's what one supplier is doing to take advantage of the mobile phone in your pocket.
Automated production of large objects such as auto body prototypes, boat hulls and surfboards traditionally requires computerized numerical control (CNC) systems costing nearly a million dollars. Thomson Cuts Costs and Production Time for Autoscale Inc.
Energy efficiency is for more than just motors. Here are some mechatronics companies making sure you get more bang for your buck when it comes to your power bill.
Digitalization is increasingly transforming mechanical engineering and manufacturing technologies, bringing with it not only unparalleled control and flexibility over production systems but so much more.
Improving System Performance One Application at a Time. PTE recently caught up with IKO, Rollon and THK to breakdown the basics in linear motion rolling guides.
Bosch Rexroth began developing linear bushings, shafts, slides, and transfer tables as prototypes in the 1960s. The first two complete linear modules with linear guides in combination with a ball screw assembly and toothed belt drive as a ready-to-install subsystem were launched in 1990 -- a quantum leap in the linear axes range which had previously been dominated by components.

Key advantages of linear motion components in aerospace applications.
Reviewing the characteristics of lead screws vs. ball screws can help you select the right screw-driven system for your linear motion application.
When designers and integrators need simple, flexible and compact linear actuation, they often turn to stepper motor linear actuators (SMLAs). The high configurability of SMLAs is among their greatest virtues, but sorting through myriad configuration options to tailor the optimal solution for a particular application can be a challenge for even the most seasoned motion engineer.
Companies look to fuel economy, energy efficiency and operating costs to improve off-highway applications.
Fully integrated linear modules can be versatile and cost-effective for linear transport applications in packaging machinery.
In today's highly competitive world, the better someone understands the advantages and benefits of direct drive technology, then the more they will have an advantage in machine building, giving them an edge over their competition.
When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.
In 2017, there's more variety to be found under the hood of a car than ever. Electric, hybrid and internal combustion engines all sit next to a range of transmission types, creating an ever-increasingly complex evolutionary web of technology choices for what we put into our automobiles. But every evolutionary tree has a few dead end branches that ended up never going anywhere.
Companies focus on customization and quality in linear motion
Ball screw assemblies are key to this patent-pending oilfield corrosion prevention solution.
Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow speed operation using a VFD. In either case, when these fans are supported by hydrodynamic bearings, it is the oil film thickness developed from the bearing-shaft interaction that limits the minimum speed that can be maintained without causing premature wear and bearing failure. This paper will present a brief overview of lubrication theory and critical design parameters to achieve slow speed operation.
Increasing pressure on many fronts is compelling mine operators to thoroughly examine every phase of their operations. Fluctuating demand that whipsaws mineral prices, government-imposed environmental regulations and rising operating costs related to maintenance downtime all pose serious challenges for the mining sector. Add pressure from customers and stakeholders for more sustainable operations as well as union demands for higher wages, and you have a scenario that requires mine operators to exercise every possible option to achieve more efficient operations.
Rolling element or sleeve bearings often are required to operate under extreme conditions. In these instances, it is more important than ever to follow proper lubrication selection and maintenance procedures to maximize effective life and efficient performance.
A reader asks whether sleeve bearings can take the place of more expensive tilting pad bearings in a high-speed compressor application.
U.S. manufacturers, such as food processors, face an unprecedented competitive environment and must look for ways to be profitable without negatively affecting the quality of finished products.
This Q&A session with various experts at Thomson Linear Systems covers linear slides & stages, clutches & brakes, bearings and actuators.
How to select a guide wheel with the properties best-suited for a given application to create a system that reduces design costs and engineering changes, and lowers warranty, assembly, installation and mounting costs.
