Ball Bearing Casters

It is a caster whose wheel rolls on ball bearings, steel balls in a race that reduce friction for smooth, easy rolling. Ball bearings are the most common caster bearing because they balance easy rolling, capacity, and value for everyday use.

A standard ball bearing rolls smoothly and suits general use. A precision ball bearing is machined to tighter tolerances and is often sealed, giving even easier rolling and longer maintenance-free life. For high-frequency or ergonomic moving, precision ball is the upgrade.

They handle light to medium-heavy loads well, up to about 4,375 lbs per caster in this collection on the larger wheels. For the very heaviest industrial loads and rough use, a roller bearing carries more and takes more abuse. Match the bearing and wheel to your weight.

These range from about 75 to 4,375 lbs per caster depending on wheel size and material. The bearing supports smooth rolling; the wheel and rig set the capacity. Divide your total load across all casters and add a safety margin, sizing up the wheel for heavier loads.
