Castor Materials

In general, castors can be subdivided into two main types:

Pressed Steel

Typical pressed steel type castors incorporate single or double ball race constructions. The balls run in tracks formed in the fork and top plate pressings which are secured together by a heavily riveted steel king pin.

Fabricated Steel

These usually consist of heavy steel forgings which are precision machined and house combinations of tapered roller bearings or ball racers. The fork legs are securely welded to the body forging giving an extremely strong construction suitable for extra heavy loads and for power towing applications.
