The S99GSB-051207 is a plastic spherical bearing with a 0.3125 in. inner diameter and 0.75 in. outer diameter, designed for maintenance-free operation in applications requiring self-alignment, vibration damping, and resistance to water, chemicals, and dust. The spherical ball is made of L280 polymer and the housing of reinforced igumid G plastic, operating between -22°F and +176°F. It has a radial static load capacity of 450 lb and axial capacity of 79 lb, with a maximum pivot angle of 29° and maximum torque of 8.85 lbf·ft. The bearing weighs 0.092 oz and is intended for press fit installation into an H7 housing bore with an h7 shaft size of 0.3125 in. ± 0.0015 in.
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.
