Introduction

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.

Product Details

1.Self-aligning ball bearing has two kinds of structure: cylindrical hole and tapered hole, and the retainer is made of steel plate and synthetic resin. Its characteristic is that the outer ring raceway is spherical shape, with automatic centrality, can compensate the error caused by different concentricity and axial deflection, but the relative inclination of the inner and outer rings should not exceed 3 degrees.

2.It mainly bears radial load and can bear small axial load.The axial displacement of the shaft (housing) is limited within the clearance limit, with automatic centering performance, allowing the normal work under the condition of relatively small inclination of the inner and outer parts, suitable for parts where the coaxiality of the supporting seat hole cannot be strictly guaranteed.

Features and Benefits

● Accommodate static and dynamic misalignment

The bearings are self-aligning like spherical roller bearings or CARB bearings.

● Excellent high-speed performance

Self-aligning ball bearings generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.

● Minimum maintenance

Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.

● Low friction

Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.

● Excellent light load performance

● Self-aligning ball bearings have low minimum load requirements.

Low noise

Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.

Application

Self-aligning ball bearing is suitable for heavy load and impact load, precision instruments, low noise motor, automobile, motorcycle, metallurgy, rolling mill, mining, petroleum, paper, cement, sugar and other industries and general machinery, etc.
