The A 7Z47MPSN12M is a self-aligning needle roller pressbearing with a 12 mm bore, designed for press-fit installation into a 27 mm panel hole. It features a drawn cup bearing and a carbon steel housing with a black oxide finish, operates between -30°C and +100°C, and supports a maximum radial load of 7800 N at up to 20000 rpm. The bearing requires a shaft with a diameter of 12.000 mm ±0.011 mm and a surface finish of 0.4 µm or finer. Installation must avoid pressing the bearing onto the insert.
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.
