Ball Bearings: Cost-Effective Quality

Posted on May 17, 2017

Throughout the years, ball and roller bearings have seen significant reductions  in price while quality has improved. Several factors have played a role in this, but production process changes and material quality improvements have most significantly changed the face of the industry.

Bearing Basics

With a constant cross section, thin section bearings allow for significant space savings and overall system weight reduction — ideal advantages when designing sophisticated and critical-application products. The cross section, which is usually square, remains constant even in bearings with large bore diameters. Often used when space limitations or specific design configurations prevent the use of conventional bearings, thin section bearings allow for versatility in many applications and come in a range of contact angle designs, including radial contact, angular contact, and four-point contact.

Levels of Precision - Choose Wisely: How Fast Your Bearings Need To Go

Posted on August 24, 2015

A rolling bearing is composed of: two rings – known as the inner and outer race – separated by a set of rolling elements, which are most often kept at a relative distance by a cage. At its most basic level a rolling bearing decreases rotational friction and supports radial and axial loads. Each element is manufactured to a certain tolerance, and the sum of the geometrical and form tolerances determines, loosely speaking, the level of performance of the bearing – rating the load it can carry axially and/or radially, the limiting speed, noise, etc.
