The S99B CM20F028030 is a metric, thin-walled, self-lubricating linear bearing with a 20 mm bore and 30 mm overall length, featuring an anodized aluminum body and a bonded Frelon® liner. It has a bore tolerance of +0.043/+0.016 mm and an outer diameter tolerance of 0/-0.021 mm, with a maximum load capacity of 6175 N and a load area of 6 cm². The bearing is available in precision or standard series, with the series specified by suffix P or S in the catalog number.
A bearing is a device that reduces friction between moving components by preventing metal-to-metal contact while assisting components (shafts, axles, and wheels) to freely rotate around a fixed axis, cutting down on heat generation and the amount of energy that is consumed. By replacing sliding motion with low-friction rolling motion, the life of the rotating components is increased. A bearing also keeps the shaft in the proper position, providing support and alignment and transferring the axial or radial loads to the housing.
The types of bearings that we offer include rolling element bearings, which consist of both ball bearings and roller bearings.
Balls are utilized as the rolling element in ball bearings; a retainer holds the balls in place and allows them to freely rotate. The balls are kept inside channels cut in both the inner and outer races. Because there is no surface contact between the balls and races, precision ball bearings have a lower load capacity for their size than other bearings.
