91 Series Kingpinless Caster

Overview

The 91 Series 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.

Options

Caster Concepts has a wide variety of caster options. Many of these not only improve function – but also provide safety and add longevity to the product. When considering safety options, the most common consideration would be caster locks, caster brakes, toe guards, and reinforced legs. Options that extend the life of a caster are primarily options that seal the bearing of the caster to prevent contamination of the precision parts.

Other options include threaded zerks for when an application is difficult and high level of maintenance is required and track brush wipers that keep debris from stopping movement or damaging a wheel. These options can be added at the time of manufacturing or after the caster is fully assembled.
