Product Description

This Series 40 medium heavy-duty rigid caster is built for maximum strength, durability, and dependable straight-line performance in demanding industrial and commercial environments. It features a 4-inch x 2-inch solid steel wheel, engineered for extreme load resistance and long-term durability in harsh operating conditions where high strength is required.

Constructed with a cold-forged top plate and heavy-duty steel wheel assembly, this caster is designed for applications where impact resistance and structural integrity are critical. The rigid design ensures stable tracking and controlled straight movement, making it ideal for heavy equipment transport and fixed-direction applications.

With an overall height of 5-5/8", a 1/2" axle, and a 5/8" kingpin, this caster supports loads up to 700 lbs. It is well-suited for industrial carts, platform trucks, and material handling systems requiring maximum durability and minimal wheel deformation under load.

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.
