Overview

The 81 Series Kingpinless Casters feature a unique single ball race design, which provides a high strength swivel section. It is valued for its simplicity and providing a tough caster for difficult industrial applications where shock loading is prevalent. The top plate and yoke base are held in alignment with 3/4 inch high quality hardened ball bearings. The ease of swiveling leads to very long life-cycles and many years of low cost operation.

Applications

To maximize the life of the entire caster, be sure you are selecting the correct wheel for your caster application.
