The A 7C55MP2609 is a metric ball bearing with a 9 mm bore, 26 mm outside diameter, and 8 mm width, designed for low-friction rotation in mechanical systems. It is constructed from AISI 52100 steel and pre-lubricated with Chevron SRI #2 grease. The part is available in no shield, single shield, and double shield variants, with radial play specified at 0.013/0.005 mm. The bearing fits shafts and housings with tolerances of -0.008 mm to -0.01 mm for bore and -0.12 mm max for outer diameter.
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.
