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.
