Product Description

This Series 40 medium heavy-duty swivel caster is designed for smooth maneuverability and dependable performance in a wide range of industrial and commercial applications. It features a 4-inch x 2-inch rubber wheel bonded to a cast iron core, providing a combination of strength, durability, and shock absorption. The rubber tread helps protect floors while reducing noise and vibration during operation.

Constructed with a cold-forged top plate and precision components, this caster includes a double-row ball bearing swivel raceway for smooth 360° rotation and easy directional control. Hardened raceways and a built-in Zerk fitting allow for routine lubrication, helping extend service life and maintain consistent performance over time.

With an overall height of 5-5/8", a 1/2" axle, and a 5/8" kingpin, this caster supports loads up to 350 lbs. The swivel design makes it ideal for applications requiring frequent movement and maneuverability, such as platform trucks, stock carts, and general material handling equipment.

The top plate measures 3-15/16" x 4-1/2" with bolt hole spacing of 2-5/8" x 3-5/8" to 3" x 3", and accommodates 3/8" mounting hardware.
