Determining the expected life a recirculating ball or roller bearing is fairly straightforward when the applied loads and duty cycle are known. Just use the bearing life equation: for recirculating ball bearings OR for recirculating roller bearings Where: L = bearing life C = bearing dynamic load capacity F = applied dynamic load These equations give the […]

Linear actuator with high resolution, 66-lb pushing force from PI
Designed for highly accurate and fast repetitive industrial applications, the L-239 compact linear actuator is the newest addition to the suite of motion control solutions available from PI (Physik Instrumente). Equipped with precision ground ball screws for higher speed and a longer service life, the L-239 high force actuator has a positioning range of 52 […]
Del-Tron Precision now has ISO 9001:2015 Certification
Linear-motion manufacturer Del-Tron Precision, Inc. has earned ISO 9001:2015 certification. The comprehensive system audits covered every aspect of operations. “Any company that has been through the certification process knows that achieving ISO 9001:2015 certification is demanding,” said Ralph McIntosh, President of Del-Tron Precision, Inc. “Each individual in our operation must be wholly dedicated to the […]
Thomson expands WhisperTrak linear actuator line with new options for higher load and speed
Thomson Industries, Inc., a leading manufacturer of mechanical motion control solutions, has expanded its WhisperTrak actuator line to give motion system designers greater ability to extend quiet, compact actuation to more demanding applications. New additions to the WhisperTrak linear actuator line double force-handling capability from 2 kN to 4 kN; provide higher-speed operation at 2 […]
What you missed at Automate 2017: Linear-motion technologies and more
We had a lot of fun last week at the Automate 2017 Show in Chicago — and some 20,000 other people did as well. Hot new robotics, motion control, and other technologies for automation wowed crowds big and small. On the front for linear motion, the big news this year at Automate was the expanding use of seventh-axis systems for extending […]
Belting Association (NIBA) and Power Transmission Distributors Association (PTDA) — Joint Industry Summit September 27 to 30
Planning is well under way for the NIBA/PTDA Joint Industry Summit, September 27-30, 2017, at The Diplomat Beach Resort in Hollywood, Florida, for top executives and those who aspire to leadership among distributors and manufacturers in the belting and power transmission/motion control industries. The one-time, combined meeting presents an opportunity for cross-channel/cross-industry networking and collaboration […]
Motion controller for linear and rotary air-bearing stages from PI
Air bearings provide advantages over mechanical bearings when frictionless vibration-free motion is required, highly constant velocity control is crucial, and when angular repeatability and geometric performance must be optimal. Nanopositioning industry leader PI (Physik Instrumente) L.P. has released a new high-performance motion control controller designed to handle 1, 2 or 4-axis of PIglide air bearing […]
Telescoping slides: Extending the reach of linear guides
Traditional round shaft and profiled rail linear guides can be joined in sections to provide virtually unlimited travel. But some applications require a linear guide that can extend into and retract out of the work area, and with profiled rail and round shaft guides, there’s not a simple, easy way to do this. For these […]
Thought leader Jeremy Miller on the migration from fluid power to electromechanical technologies
At a recent visit to the Parker Hannifin Electromechanical and Drives Division in Irwin, Pa., I got the chance to hear the perspective of Jeremy Miller, Product Manager — Linear Mechanics. I asked him about some of the major design objectives Parker’s customers cite when changing their designs from fluid power to electromechanical. Click here […]
Festo showcases transformative flexible automation at Automate 2017
Festo showcases at Automate 2017 in Chicago (April 3 to 6) the Handling Guide Online — a new design tool that lowers engineering overhead and speeds delivery of flexible handling subassemblies. The company also introduces new Piezo proportional air valves for better control than traditional solenoid valves in many applications. These and other products, including a family of gantry-based handling […]
