Product Description

This Series 40 medium heavy-duty swivel caster with top lock brake is designed for controlled mobility, stability, and long-term durability in industrial and commercial applications. It features a 5-inch x 2-inch polyurethane wheel with a plastic core, offering a strong balance of load capacity, quiet rolling performance, and floor protection.

Built with a cold forged top plate and base, this caster provides exceptional structural strength and reliability. The double-row ball bearing swivel raceway ensures smooth rotation, while hardened raceways and a zerk lubrication fitting help extend service life and reduce maintenance. The stainless steel yoke adds corrosion resistance, making it suitable for food service and washdown environments.

With an overall height of 6-1/2" and a standard A1 top plate (3-15/16" x 4-1/2"), this caster supports loads up to 800 lbs. The integrated STS top lock brake allows secure wheel locking when stationary, making it ideal for platform trucks, stock carts, and equipment requiring both mobility and stability.
