self aligning ball bearing
Self-Aligning Ball Bearing is suitable for the Shaft be brought out a larger deflection or the bearings are not on the central line. The friction coefficient is smaller than other bearings, so it can keep lower temperature even if under high speed rotation. This Bearing have 1200, 2200, 1300, 2300,1200K, 1300K, 2200K, 2300K series.
The self-aligning ball bearing has two rows of balls and a common concave sphere raceway in the outer ring. The bearing is consequently self-aligning and insensitive to angular misalignments of the shaft relative to the housing. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearing has the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
Self aligning ball bearings are suitable for applications where misalignment can arise from errors in mounting or shaft deflection. The steel balls, cage, and inner ring can rotate freely at a certain angle, as it is stated that the bearings have self-aligning features. Accordingly, misalignment of the bearing shaft due to the machining and installation of the shaft and housing will be automatically adjusted.
Double row self-aligning ball bearings have a sphere raceway in the outer ring and a double raceway in the inner ring. This feature gives the bearings their self-aligning property, permitting angular misalignment of the shaft relative to the housing. They are therefore particularly suitable for applications where misalignment can arise from errors in mounting or from shaft deflection.
Double row self-aligning ball bearings are mainly used to carry radial loads and light axial loads, but can’t carry pure axial loads.
