Many track-roller linear guides necessitate lubrication at two different points in their assembly: Within the rolling-element rotary bearings at the heart of each track-roller wheel and Along the linear track-roller raceway. As with most any mechanical power-transmission devices, lubrication of these two critical areas extends the linear guide’s service life by minimizing or eliminating the […]

Bosch Rexroth now offers a new lineup of BSCL linear guides. The new BSCL ball rails address applications requiring linear bearings in the mid-performance range, and the new structural design delivers an optimum price to performance ratio. BSCL ball rails are available in five sizes, six runner block types, three preload classes and three accuracy classes. […]
Linear bearing from Rollon handles light-to-moderate loads in linear motion applications
Rollon has introduced its lightweight MiniRoller Rail linear bearing. Ideal for applications that require moderate loads, it features smooth and silent operation and an adaptive design that is easy to customize and integrate into assemblies. MiniRoller Rail eliminates the noise, difficult assembly, misalignment and unnecessary weight typically associated with using linear guides with recirculating ball […]
igus modular linear axis for travels of any length
igus, the Germany-based manufacturer of motion plastics, is launching the drylin Endless Gear linear module (EGW), a modular, lubrication-free linear guide with rack and pinion drive. The modular system can be extended to any travel length, costs little, and is almost as light as the guide for a toy train. Several carriages can travel on […]
Ametek Haydon Kerk Pittman introduces EGS low-profile precision rail
As a world leader in compact linear motion systems, Ametek Haydon Kerk Pittman (HKP), a business unit of Ametek, is pleased to announce its new EGS04 low-profile precision rail. The EGS “efficient guided system” is ideally suited for customers in lab automation and electronic assembly whose applications require high speed and highly efficient point-to-point motion. […]
Rediscovering ball splines for robust linear and rotary motion
Ball splines were once a staple for machine designers seeking an elegant way to integrate rotary and linear motion. Driven by pressures to speed their machines to market, many designers found it faster to implement prepackaged solutions in which rotary and linear motion shafts had already been integrated. By Charles Isaac • Thomson Industries Chris […]
Low-load polymer bushing bearings increase motion system design flexibility
Thomson Industries, Inc., has added a polymer bushing to its line of state-of-the-art Ball Bushing bearings. It expands the company’s extensive bearing portfolio, providing design engineers a new option that helps them avoid overdesigning for low-load applications. Thomson polymer bushing bearings provide a reliable solution for machines where moment load is non-critical (30 to 40 […]
