AURORA Bearing series features a one piece steel race-way, swaged around the ball for a smooth, precise, close tolerance fit, along with the benefit of the strength and vibration resistance of steel. 

Aurora 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 3 or 4 piece construction, with an inner ball, an outer ring, and a one or two piece brass, bronze, or copper alloy race between. Since the early 1950’s users of these bearings, which are also marketed with a “FLBG”, “RS”, or “VBC” prefix, have had to accept.the low strength and poor vibration resistance of these bearings due to the low strength race material. Aurora’s LCOM bearings incorporate superior materials and manufacturing processes to overcome the performance deficiencies associated with “LS” bearings.
