Service Caster metal thread guard for 6 inch industrial caster wheels. Designed for use with 1/2 inch axles.
Thread guards are designed to protect caster wheel bearings by preventing debris such as loose threads, string, and fibers from wrapping around the axle. Installed between the spanner bushing and caster leg, they help reduce buildup and maintain smooth wheel performance.
Commonly used in textile and similar environments, these metal thread guards improve caster reliability and extend service life by keeping contaminants away from critical components.
