Product Description

This Series 40 medium heavy-duty rigid caster is built for high-capacity performance, stability, and long-lasting durability in industrial and commercial environments. It features a 5-inch x 2-inch polyurethane (plastic core) wheel that provides smooth rolling action, reduced vibration, and excellent floor protection while supporting heavier loads.

Constructed with a cold forged top plate and base, this caster is engineered for strength and reliability under continuous use. The hardened raceways, double-row ball bearing swivel raceway (Series 40 platform construction), and integrated zerk lubrication fitting ensure smooth operation and reduced maintenance requirements. The stainless steel yoke adds corrosion resistance, making it suitable for food service, warehouse, and utility applications.

With an overall height of 6-1/2", a 1/2" axle, and a 3/8" A1 mounting plate, this caster supports loads up to 800 lbs. The rigid design provides consistent straight-line movement, making it ideal for platform trucks, stock carts, and material handling equipment.
