The Fairbanks Company 4 in. D Swivel Polyurethane Caster 500 lb 1 pk

The revolutionary concept for medium/heavy-duty casters. Two significant features make this caster different from all the rest. A one-piece fork/horn and a one-piece combination lower ball race and king pin. It's never been accomplished before. A deep-drawn formed fork/horn, with no welds mounted on a 4 in. x 4-1/2 in. top plate. The one-piece fork/horn design distributes loads across the larger portion of the ball race. The one-piece combination lower ball race and king pin improves structure rigidity and easier swiveling. The 3/4 in. diameter king pin is orbital cold forged for superior strength and stability. This unique design provides smooth swivel action, less swivel strain, assuring longer life. Lubricated, hardened roller bearings and ground bushings give you a caster that can withstand loads up to 1200 lb. Powder coating fights corrosion. Made with superior quality control at every manufacturing step. These are the medium/heavy-duty answers for strong caster applications. All at the most competitive prices.
