Bearing

Advances in materials, design, and processing have combined to triple bearing life.

In the graphics on the far right, a cross section of a linear guide for high-precision pick-and-place applications shows how two segments (instead of four complete bearings)
support the carriage.

Bushings and bearings made of Graphalloy, a graphite-and-metal alloy, work in hostile environments and handle temperatures ranging from cryogenic to 1,000°F.

Grease circulates with the aid of a ball cage.

Track rollers use a large-diameter bearing surface to carry loads and a small-diameter bearing to guide the loads.

Roller bearings are one of four sections in the SKF Interactive Engineering Catalog on CD-ROM.

This shows a double-sided way with two single-sided bearing blocks.

Series M turntable bearings have ballpath diameters ranging from 16 to 43 in.

Corrosion-resistant plastic ball bearings reduce system cost, enhance performance, reduce weight and lengthen life in hostile environments. So it's no surprise that the plastic-ball-bearing industry has recently expanded applications for the bearings to include jobs that have been traditionally served by steel bearings.

The top shaft is supported by angular
contact spherical plain bearings in a so-called O arrangement.

CW Bearing produces medium to high-volume bearings for OEMs.

A patented cage design and self-contained lubricant film lasts longer than traditional lubricants in bearings of all kinds.

The bearings from Rex Bearing Div., Rexnord Corp., Downers Grove, Ill., are made of a Teflon-woven fabric supported by a filament-wound fiberglass shell.

Air bearings for linear applications, segmented bearings that can be installed into hard-to-reach places, and thermoplastic bearings molded with integral pulleys or gear teeth are just a few of the recent developments from bearing manufacturers.
