The S99ASZM20F032045 is a metric linear bearing with a 20 mm bore and 45 mm overall length, featuring an anodized aluminum body and a bonded Frelon® liner for self-lubricating operation. It is designed for open-series mounting with a slot width of 10.8 mm and a slot angle of 60°, and includes a retention hole for retaining ring A and O-ring 6R11ML027525. The bearing supports a maximum load of 9265 N and has a bore tolerance of +0.129/+0.096 mm, with an outer diameter tolerance of 0/-0.021 mm. The part is identified in the catalog as part of the standard Frelon-lined bearing series.
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.
