Conveyor 1202 High-precision Self-aligning ball bearing
In a self-aligning bearing, the inner ring has two raceways and the outer ring has a single spherical raceway with its center of curvature coincident with the bearing axis. Self-Aligning Double Row Ball Bearings are designed to work in applications where severe misalignment exists whether from mounting or shaft deflection. The concave raceway of the outer ring in combination with two rows of balls operate over a wide range of contact angles.
The self-aligning ball bearing has two structures: cylindrical hole and tapered hole. The material of cage is steel plate and synthetic resin. Its characteristic is that the outer raceway is spherical and has automatic alignment, which can compensate for the errors caused by different concentricity and axis deflection, but the relative inclination of the inner and outer raceways should not exceed 3 degrees.
Advantages of self-aligning ball bearing:
(1)High Quality Steel-Ultra clean steel to extend bearing life by up to 80%.
(2)Advanced Grease Technology
(3)High Grade Balls - Quiet and smooth operation even at high speed.
(4)Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life.
