The S99GSBM020804 is a press-fit spherical bearing with a 2 mm inner diameter and 8 mm outer diameter, designed for low-friction rotational motion in applications requiring self-alignment. The housing is made of igumid G polymer and the ball of L280 polymer, with an operating temperature range of -30°C to +80°C. It is maintenance-free, chemical and UV-resistant, and lightweight. After press fit, the inner diameter tolerance is +0.054/+0.014 mm. The bearing supports a maximum radial load of 300 N and axial load of 60 N, with a maximum torque capacity of 1 Nm. It is designed for use with H7 housing bores and h7 shafts. The part weighs 0.1 g.
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.
