Powder coating and media blasting shortens the life span of most casters.  These special casters were designed for powder coating operations to increase the lifespan of the caster.  Media blasting, such as with aluminum oxide, will not prematurely ruin the swivel bearing or the bronze bearing in the wheel.

Jamming : The one-piece design of bronze bearings is particularly advantageous in applications like powder coating, media blasting, or painting where airborne particles are common. This casters design prevents stone dust and particulate matter from entering and potentially jamming the bearing, enhancing operational reliability, reducing maintenance needs, and minimizing downtime in particle-rich environments.
