61 Series Caster


61 Series Kingpinless casters have become highly utilized industrial caster while evolving into a valuable investment for rugged applications that minimize maintenance costs. It is valued for its simplicity and providing a tough caster for industrial applications where shock loading is prevalent. The heat-treated inner and outer rings are held in alignment with 1/2 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 kingpinless style of caster is a highly desired option when manual ergonomic operation is needed.


The 61 Series Kingpinless Caster excels in rugged, abusive applications such as floor tow lines, works-in-progress carts, trash trucks, dough troughs, fixture carts, drywall dollies, autoclave dollies, tread book trays, automotive body dollies, gantry cranes, lift truck battery handling equipment, automated guided vehicles, and conveyor systems.

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.
