A 7Y55-GSS1805 is an ABEC 3 extended inner ring ball bearing with a 0.055 inch bore, 0.1875 inch outside diameter, and double shields, lubricated with oil meeting MIL-PRF-6085. It has a dynamic load rating of 22.4 lbf and a static load rating of 7.68 lbf, with radial play of 0.0002 to 0.0005 inch. The bearing measures 0.055 inch in width and 0.234 inch in flange width, with inner and outer land diameters of 0.1094 inch and 0.150 inch respectively.
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.
