Self-aligning ball bearing introduction

The self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin and the like. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate for errors caused by different degrees of heart and shaft deflection, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

The self-aligning ball bearing is a bearing equipped with a spherical ball between the inner ring of the two raceways and the outer ring of the spherical raceway.

The center of curvature of the outer raceway surface is identical to the center of the bearing, so it has the same self-aligning function as the self-aligning ball bearing. When the shaft and outer casing are deflected, they can be adjusted automatically without increasing the bearing load. Spherical roller bearings can withstand radial loads and axial loads in both directions. The radial load capacity is large, and it is suitable for heavy load and impact load. The inner ring inner diameter is a tapered bore bearing that can be mounted directly. Or use the adapter sleeve and the removal cylinder to mount on the cylindrical shaft. The cage uses a steel stamping cage, a polyamide forming cage and a copper alloy cage.

The self-aligning ball bearing has two structures of a cylindrical hole and a tapered hole, and the material of the cage is steel plate, synthetic resin and the like. The characteristic is that the outer ring raceway has a spherical shape and has self-aligning property, which can compensate for the error caused by different heart degrees and shaft deflections, but the relative inclination of the inner and outer rings must not exceed 3 degrees.

Can withstand large radial loads while also withstanding a certain axial load. The outer ring raceway of this type of bearing is spherical, so it has the function of self-aligning. When the shaft is bent or tilted so that the center line of the inner ring and the center line of the outer ring are inclined no more than 1°~2.5°, the bearing can still work. .

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.

Product Features:

It is mainly subjected to radial loads and can withstand small axial loads. The axial displacement of the shaft (outer casing) is limited to the clearance limit, and has automatic self-aligning performance, allowing normal operation under the condition that the inner and outer sides are relatively inclined, and is suitable for the parts in which the support seat hole cannot strictly guarantee the coaxiality.
structure type:
The self-aligning ball bearing with dust cover and sealing ring has been filled with the proper amount of grease. It should not be heated or cleaned before installation. It does not need to be relubricated during use. It can adapt to the operating temperature of -30°C to +120°C. The main purpose of self-aligning ball bearings: suitable for precision instruments, low-noise motors, automobiles, motorcycles and general machinery, etc. It is the most widely used type of bearing in the machinery industry.
