Aurora Bearing Co. designs higher-level bearings

In addition, this series is optionally available with Aurora’s proprietary AT series PTFE liner, for a zero clearance, self-lubricating fit. 

The bearings were designed to offer a higher level of performance with dimensional interchangeability for the “LS” spherical bearing category; a market segment, which has remained largely, unchanged since the 1950s.  “LS” bearings are characterized by being of three or four piece construction, with an inner ball, an outer ring, and a one or two piece brass, bronze, or copper alloy race between.
