About Caster Wheel Bearings
Bearings wear from heavy use, dirt, and moisture. When a caster wheel seizes, gets noisy, or feels gritty when spun, the bearing has failed. Replace the bearing rather than the wheel for simple fixes.
How to Choose
1. Identify Failed Bearing
Wheel won't spin freely, feels gritty, or makes noise = bearing failed.
2. Match Bore Size
5/16, 3/8, 1/2 inch most common. Match the existing axle diameter.
3. Sealed vs Open
Sealed: wet/dirty environments, longer life, slightly higher rolling resistance. Open: clean indoor, lower cost.
4. Ball vs Roller
Ball: lower load capacity, smoother roll. Roller: higher load, stiffer roll. Match to caster spec.
