A self-clinching, self-lubricating sintered bronze pressbearing with a 12.03 mm bore and 20.6 mm panel hole diameter, designed for mounting in panels up to HRB 65 hardness, with a carbon steel retainer and black oxide finish. It operates between -29°C and +93°C, requires a shaft with HRC 95 minimum hardness and 0.4 µm or finer finish, and supports a maximum radial load of 2550 N at 8060 rpm. The bearing is self-aligning to ±5°, has a panel thickness of 1.5 mm, and a total height of 16.3 mm. Installation requires a punch or drilled hole with diameter 12.7 mm and an installation force of 49 kN using a press tool of 22 mm diameter and an anvil of 21.05 mm diameter, with a minimum centerline distance of 12.7 mm from the panel edge.
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.
