How to calculate crossed roller bearing life (with various load types)

February 11, 2021 By Danielle Collins Leave a Comment

crossed roller bearing

A crossed roller bearing is a type of rotary bearing that uses cylindrical rollers arranged in a crisscross pattern, with each roller oriented at a 90 degree angle relative to the one adjacent to it. This arrangement allows crossed roller bearings to withstand radial, axial, and moment loads, so they can often replace dual-bearing arrangements, for […]

Why is viscosity important for bearing lubrication?

January 10, 2019 By Danielle Collins Leave a Comment

viscosity

Lubrication — or, more correctly, improper or insufficient lubrication — is one of the leading causes of equipment failures in industrial applications. Without it, sliding, rolling, or meshing surfaces experience significant friction, heat, and wear, leading to increased noise, loss of accuracy, and reduced equipment life. One of the most important characteristics of a lubricant […]

How to specify motion components for cleanroom environments: Part 2

September 5, 2018 By Danielle Collins Leave a Comment

motion components for cleanroom

In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we looked at how to reduce particle generation due to friction between moving components. In this second part, we’ll look at another source of contamination — outgassing — […]

How to specify motion components for cleanroom environments: Part 1

August 29, 2018 By Danielle Collins Leave a Comment

motion components for cleanroom

In this two-part article, we cover the products, materials, and features that designers and engineers should specify when choosing motion components for cleanroom environments. In part 1, we look at how to reduce particle generation due to friction between moving components. Designers of automation systems are tasked with many competing demands, such as balancing cost and performance, […]

Rotary bearings: Summary of types and variations

March 14, 2018 By Danielle Collins Leave a Comment

rotary bearings

Rotary bearings are common components in motion systems. They’re used in gearboxes, motors, pulleys, fans, pumps—virtually any time a shaft is rotating, rotary bearings are there to reduce friction and support radial or axial loads. The classification of rotary bearings begins with the type of bearing that supports the load—ball or roller. Within the ball […]

7 linear motion principles that electrical engineers should know

August 22, 2017 By Danielle Collins Leave a Comment

Linear motion

Electrical and controls engineers are normally tasked with selecting and integrating the electronic components that go into a motion control system, such as motors, drives, controls, feedback devices, and HMIs. In doing so, their primary concerns tend to be on making the various components communicate with each other, working through complex equations for drive tuning, […]

Six FAQs about bearings and choosing between oil and grease

July 16, 2016 By Lisa Eitel Leave a Comment

Rotary bearings consist of smooth rollers or metal balls and inner and outer surfaces (races) against which the rollers or balls travel. These rollers or balls carry load carrier and let axes spin freely. Bearings typically encounter radial and axial load. Radial loads are perpendicular to the shaft, and axial loads occur parallel to the […]
