New Profile Rail Linear Recirculating Bearings from Lintech
Lintech’s MR, ARC, and HRC Profile Rail Linear Recirculating Bearings incorporate two or four rows of recirculating balls arranged in a 45 degree contact angle with the raceway. The rigidity under moment and torsional loads is increased by this design. Larger ball size is used to enhance the load capabilities. This design offers equal loading in all […]
How to estimate your linear actuator needs with minimal application data
Choosing linear motion components during the development phase of a project has been a source of frustration for designers and application engineers for decades—especially when it comes to complex subassemblies such as linear actuators. Consider for a moment the influence that a linear actuator has on the overall machine design. First of all, in an actuator, […]
When do you need a ball screw?
The gap is narrowing between applications that require ball screws and those that are suitable for lead screws, and it’s becoming more difficult for engineers and designers to determine which technology is best for their machine. Advances in lead screw designs and materials have given them higher load capacities and better positioning accuracy, making them a sound choice […]
Motion applications: Electric actuators in new designs
Electric actuators come in versions as small as syringes for medical applications to those big enough to drive industrial presses. These muscles of precision motion usually incorporate an electric motor and rotary-to-linear device for conversion of torque to linear force. No matter the application, electric actuators deliver repeatability that’s indispensable for moving loads to a […]

To give close-up insight into its latest products and services, Bosch Rexroth created a mobile, factory automation road show. To help time-stressed engineers stay on top of the latest technologies, Bosch […]
The top 5.5 linear motion stories of 2016
As a writer and editor, it’s always fun (and sometimes surprising) to look back at the end of the year and see what articles our readers were most interested in. And for you, our readers, it offers the chance to take a quick look at what are, at least to some of your peers, important topics […]
When is static load capacity important?
When sizing a recirculating bearing, most designers and engineers focus on bearing life, which is based on dynamic load capacity. This is the load at which a linear recirculating bearing will, with 90 percent certainty, achieve the targeted service life before fatigue occurs. Static load capacity, on the other hand, is the force that causes permanent […]
Bosch Rexroth launches new microsite for resource kits
In an effort to make life even easier for time-challenged engineers, Bosch Rexroth has launched a microsite — movewithrexroth.com — for its latest factory automation products and the associated Resource Kits. This website features easy navigation through ten of Rexroth’s newest products in the areas of Electric Drives and Controls, Linear Motion and Mechatronics, Plastic Chain […]
Onboard electronics make linear actuators safer and smarter
By Chad Carlberg | Product-line manager for linear actuators, Thomson Linear • Today’s electromechanical actuators deliver performance that’s comparable or even superior to other technologies in outdoor applications. They’re often cleaner with lower cost of ownership than predecessors. Traditional electric actuators provide basic machine functionality (to push and pull loads on command via switches) but more […]
