Self-Aligning Ball Bearing 2300 Series
2300 series self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring. They are available open or sealed. The bearings are insensitive to angular misalignment of the shaft relative to the housing, which can be caused, for example, by shaft deflection.
The self aligning ball bearing 2300 series has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate the error of the heart ball bearing by different degrees of heart and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.
The inner diameter of the self-aligning ball bearing is cylindrical or conical. The conical inner bore has a taper of 1:12 or 1:30. In order to enhance the lubrication performance of the bearing, an annular oil groove and three oil holes are machined on the outer ring of the bearing.
Application
Self aligning ball bearings are widely applied to heavy loads and shock load, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, mill, mining, petroleum, paper, cement, squeezed sugar industry and general machinery.
