ABSTRACT:
This invention discloses a novel and improved method of seating a bearing, especially for use in chair controls for tiltable chairs. A multi-pointed star-shaped hole is cut in the support and a bearing, preferably made of nylon, which has a series of circular rings on its periphery, each ring diminishing in diameter, is placed in the hole as far as it will go. The bearing is then fused into the hole and the hole cuts the bearing so that shavings are forced into the undercut part of the next largest ring. This provides a secure and tight fitting bearing and removes any necessity for bearings to be made of exact tolerances. The process may also be subject to a fully automated process at a greatly reduced cost.
