Hamilton’s stainless steel inline caster was developed for a major aerospace part supplier. The aerospace company ordered two of these casters for a clean room environment. Each has a carrying capacity of 15,500 lbs. The caster stands 10 1/8” tall and 21” long equipped with two 8 inch diameter by 2.2 inch wide double flanged track wheels. Four 40 millimeter double sealed precision stainless steel ball bearings were press fit into each wheel with 1-1/4 inch axles. The pivot block used axles 1-1/2 inch in diameter. The application required the load to remain completely level to compensate for floor irregularities. The inline wheels support each other with a pivot point in the center of the caster. When the front caster encounters irregularities in the floor, the back wheel keeps the load level.
