The A 7Q 7M0409 is a thrust bearing washer, part of a series that includes hardened CR1075 steel washers with a thickness tolerance of ±0.03 mm and an outer diameter of 9 mm, designed for use with a 4 mm bore. The washer is used in conjunction with S.A.E 1018 steel balls hardened to HRC 60 min and a molded nylon retainer rated for maximum 120°C operation. Load ratings for the complete bearing set are 227 N at 10 rpm and 120 N at 100 rpm, with load capacity at 900 rpm approximately half that at 100 rpm.
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.
