Series 21-31 Regular Duty Caster
Capacity up to 650 lbs.These swivel and rigid regular-duty casters are all steel, featuring the exclusive LOCKWELD construction. Available in sizes 2" - 6". LOCKWELD is a Fairbanks exclusive. This unique construction replaces the king pin with a rigid, strong welded structure. This gives you perfect alignment and more structural strength for extra miles of service. Economical, all-purpose construction of cold-formed steel raceway, hardened ball bearings and hardened steel spanner bushings. Their simple design renders their use as an all-purpose caster that can provide long, reliable service. Zinc electro-galvanized finish for a bright finish and rust prevention. The leg design disperses shocks and overloads across a larger portion of the ball race, resulting in a smoother swiveling action.
