Heavy Duty Caster Set 4in V-Groove Wheels, 2 Rigid & 2 Swivel, 4PK

This 4-piece Heavy Duty Caster Set with V-Groove wheels is engineered for precision tracking and exceptional load capacity in industrial applications.

The cold-forged top plate, hardened raceways, and double row ball bearing swivel raceway deliver long-lasting strength and maneuverability. Zinc-plated metal components resist corrosion, while Zerk fittings in both the swivel race and hub ensure easy lubrication for extended service life. The robust design includes a 5/8in diameter king pin, 1/2in axle, and welded legs for maximum stability. Perfect for material handling systems, platform trucks, and guided track applications, these casters offer a reliable, high-capacity solution for demanding work environments.
