The Extra Heavy Duty-Kingpinless Caster has become a highly accepted industrial caster while evolving into a valuable investment for rugged applications by minimizing maintenance costs. It is valued for its simplicity and providing a tough caster for 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 construction of the swivel section puts the ball bearing in a sheer load that provides great strength while providing smooth operation when swiveling in a loaded state. The ease of swiveling leads to very long lifecycles and many years of low cost operation.


Suitable for power drawn applications, fiberglass mold dollies, aircraft wing and spar tooling, machinery, engine and paint line dollies, body dolly carts, material carts, chassis rack carts, towed trash gondolas, aircraft maintenance stands, production line delivery trailers and automated guide vehicles. To maximize the life of the entire caster be sure you are selecting the correct wheel for your caster application.
