Bearing races are precision machined out of rough C-1045 steel forgings. The raceways are then heat treated to eliminate brinelling of the surface when the caster is subjected to shock loads. A 1-1/4″ tapered thrust bearing is used to complete the precision fit of raceway. The 80 series casters give you high load capacity at a good value. These casters are used for power drawn equipment like stamping racks, trash gondolas, material delivery trailers, etc. They are also widely used on aircraft ground support equipment.
