The S99GLZM5075100 is a metric open linear plain bearing with a 50 mm bore and 75 mm outer diameter, featuring an anodized aluminum housing and a J® polymer liner for maintenance-free operation. It is designed for use with hard anodized aluminum shafts of 8-16 RMS surface finish and supports shafts up to 50 mm in diameter. The bearing operates continuously between -14°C and +90°C, with intermittent use up to +120°C. Dynamic load capacity is 2810 kgf at 0°, 2413 kgf at 90°, and 1377 kgf at 180°; static load capacity is 19670 kgf at 0°, 16919 kgf at 90°, and 13769 kgf at 180°. The part is secured with set screws (not included) and is intended for supported shaft applications.
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.
