The S99GLZM2032045 is an open-series linear plain bearing with a 20 mm bore and 32 mm outer diameter, designed for supported shafts. It features an anodized aluminum housing and a J® polymer liner, offering maintenance-free operation. The bearing supports continuous operation between -14°C and +90°C, with intermittent exposure up to +120°C. It requires a hard anodized aluminum shaft with an 8-16 RMS surface finish for optimal service life. Dynamic load capacity is 505 kgf at 0°, 404 kgf at 90°, and 202 kgf at 180°, while static load capacity is 3540 kgf at 0°, 2832 kgf at 90°, and 1416 kgf at 180°. The housing bore tolerance is +0.091/+0.030 mm. The bearing length is 45 mm, with groove width and depth of 11.6 mm and 1.6 mm respectively. Secure mounting is achieved via set screws (not included).
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.
