Cylindrical or Tapered Self Aligning Ball Bearings 1303, 1304 With Two Rows of Balls
The self-aligning ball bearings have two rows of balls and a common concave sphered raceway in the outer ring. There're two structures of bore: cylindrical or tapered. It is particularly suitable for applications where considerable shaft deflections or misalignment are to be expected. Additionally, the self-aligning ball bearings have the lowest friction of all rolling bearings, which enables it to run cooler even at high speeds.
The self-aligning ball bearings are widely used in mining machinery, power machinery, heavy machinery and textile machinery etc.
