Introduction to bearings:  

The self-aligning ball bearing is a bearing equipped with spherical ball bearings between the inner ring of two raceways and the outer ring of a spherical raceway.   The center of curvature of the raceway surface of the outer ring is consistent with the center of the bearing, so it has the same aligning function as the automatic aligning ball bearing.  When the shaft and shell are bent, it can be adjusted automatically without increasing the bearing burden.  Self-aligning roller bearings can bear radial loads and axial loads in two directions.  Large radial load capacity, suitable for heavy load, impact load.  The inner diameter of the inner ring is the bearing with taper hole, which can be installed directly.  Or the use of fixed sleeve, disassembly cylinder installed on the cylindrical shaft.  The cage uses steel plate stamping cage, polyamide forming cage and copper alloy turning cage.   Self-aligning ball bearings have cylindrical holes and conical holes two kinds of structure, cage material has steel plate, synthetic resin and so on.  The raceway of the outer ring is spherical and has automatic centering, which can compensate the errors caused by different concentricity and shaft deflection of the self-aligning ball bearing, but the relative inclination of the inner and outer rings shall not exceed 3 degrees.   It can bear large radial load and certain axial load at the same time.  The raceway of the outer ring of this kind of bearing is spherical, so it has self-aligning performance. When the axis is bent or tilted by force, the relative tilt of the center line of the inner ring and the center line of the outer ring does not exceed 1° ~ 2.5°, the bearing can still work.   Self-aligning ball bearing bore cylindrical and conical two kinds.  The taper of the conical inner hole is 1:1-2 or 1:30.  In order to enhance the lubrication performance of the bearing, annular oil groove and three oil holes are processed on the bearing outer ring.  

Bearing overview:  

Self-aligning ball bearings have cylindrical holes and conical holes two kinds of structure, cage material has steel plate, synthetic resin and so on.  Its characteristic is that the outer raceway is spherical and has automatic centering, which can compensate for different concentricity and deflection of shaft to make self-aligning ball bearings   Into the error, but its inner and outer ring relative tilt shall not exceed 3 degrees.  

Basic functions:

It is mainly used for bearing radial load. While bearing radial load, it can also bear a small amount of axial load, but it generally cannot bear pure axial load, and its limit speed is lower than that of deep groove ball bearings.  This kind of bearing is mainly used in the double support shaft which is easy to bend under the load, and in the parts where the double socket hole cannot guarantee strict coaxiality, but the relative inclination of the inner ring center line and the outer ring center line shall not exceed 3 degrees.   Self-aligning ball bearings are suitable for bearing heavy loads and impact loads, precision instruments, low noise motors, automobiles, motorcycles, metallurgy, rolling mills, mines, petroleum, paper making, cement, sugar pressing industries and general machinery, etc.  

Basic classification:  

The self-aligning ball bearing has two rows of steel balls and two raceways in the inner ring. The raceways in the outer ring are inner spherical shape and have the performance of automatic self-aligning.  It can automatically compensate coaxiality errors caused by shaft deflection and shell deformation, and is suitable for supporting seat holes that cannot guarantee strict coaxiality.  This kind of bearing mainly bears radial load, while bearing radial load, it can also bear a small amount of axial load, usually not used to bear pure axial load, such as bearing pure load, only one row of steel balls.   Specific classification and model comparison:   1. Cylindrical hole aligning ball bearing (10000 type);   2. Tapered hole self-aligning ball bearing (type 10000 K);   3, self-aligning ball bearing with set sleeve (10000K +H10000 type)   Note: Self-aligning ball bearings have cylindrical holes and tapered holes (10000K type), which mainly bear radial load and can bear small axial load at the same time. The axial displacement of the shaft (housing) is limited within the clearance limit, with automatic self-aligning performance, and the relative inclination of the inner and outer parts is not more than -.  Is suitable for supporting seat holes can not strictly ensure the coaxial parts.   3, self-aligning ball bearing with set sleeve (10000K +H10000 type)   Note: Same as above, the bearing is mainly used for shoulderless optical shaft, easy to assemble and disassemble, radial clearance can be adjusted with fixed sleeve.   Basic knowledge:   Self-aligning ball bearing product characteristics ------ mainly bear radial load, at the same time can bear small axial load.  The axial displacement of the shaft (shell) is limited within the clearance limit, with automatic self-aligning performance, allowing the normal work under the condition of relatively small inclination inside and outside, suitable for supporting seat holes can not strictly ensure the coaxiality of the parts.   Self-aligning ball bearing structure ------ With dust cover and sealing ring self-aligning ball bearing assembly has been filled with proper amount of grease, should not be heated before installation and do not need to clean, do not need to be lubricated in the process of use, adapt to the operating temperature between -30 ℃ and + 120 ℃.  Main uses: suitable for precision instruments, low noise motors, automobiles, motorcycles and general machinery, etc., it is the most widely used kind of bearings in the machinery industry
