The S99GSB-071509 is a maintenance-free, self-aligning spherical bearing with a 0.4375 in. inner diameter and 0.9375 in. outer diameter, designed for use in harsh environments where lubrication is impractical. The ball is made of L280 polymer and the housing of reinforced igumid G plastic, enabling operation from -22°F to +176°F. It supports a maximum radial load of 843 lbs and axial load of 101 lbs, with a pivot angle of 25° and maximum torque capacity of 22.13 lbf·ft. The bearing weighs 0.5 oz and requires an H7 housing bore and h7 shaft for optimal performance.
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.
