The BSNPLNMMB505550 is a split-type plain sleeve bearing with a 50 mm bore, 55 mm outer diameter, and 50 mm length, featuring a carbon steel backing and a self-lubricating composite liner of sintered bronze and PTFE for maintenance-free operation. The bearing is designed for sliding motion applications and provides an installed bore diameter of 50.110 mm. Its split design accommodates axial assembly around shafts.
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.
