Tips for mounting linear ball bearings: Pillow block housings

September 11, 2020 By Danielle Collins Leave a Comment

Linear ball bearings and round shafts are often used in applications that call for ease of use and simple mounting requirements. For example, where profiled rail guides require full support along their length, linear ball bearings, or bushings, can be used in many applications with shafts that are supported only at their ends. However, unlike […]

What are fixed and floating bearings in the context of linear motion?

August 7, 2020 By Danielle Collins Leave a Comment

fixed and floating bearings

There are two instances when the terms “fixed bearing” and “floating bearing” are used in linear motion: to describe the support bearings used on ball and lead screws, and to describe linear guides mounted in parallel. And while the meanings of the terms are the same in both situations, their applications are different in each […]

New flanged linear bushings available from Samick

April 16, 2020 By Danielle Collins Leave a Comment

Manufacturers are faced with the enormous challenge of minimizing risks in their manufacturing processes while at the same time lowering costs and improving product quality. Flanged linear bushings from SAMICK can meet these customer requirements. Whereas standard linear bushings must be used in combination with casings, flanged linear bushings are directly mounted onto the housing […]

What are rail brakes and when should you use them?

March 20, 2020 By Danielle Collins Leave a Comment

The servo and stepper motors that drive linear motion systems often include a braking function, or, in the case of stepper motors, detent torque that helps prevent the motor (and, therefore, the load) from moving when powered off. But in some applications, a secondary brake is required — either to provide redundancy and meet safety requirements […]

What are some alternatives to L10 bearing life?

March 10, 2020 By Danielle Collins Leave a Comment

If you work with linear ball or roller bearings, you’re familiar with the L10 bearing life equation, which states that bearing life is equal to the bearing’s rated dynamic load capacity, divided by the applied load, raised to a power of 3 (for ball elements) or 10/3 (for roller elements). Introduced in 1947 by Gustaf […]

What makes a linear guide suitable for high temperature use?

February 14, 2020 By Danielle Collins Leave a Comment

linear guide for high temperature

For most recirculating ball and roller linear guides, the allowable operating temperature range is -10° to 80° C, with some configurations rated up to 100° C for brief periods. But not all applications fall within this temperature range, and each component in the linear bearing assembly (housing, rail, balls, seals, etc.) has a different maximum […]
