Can bear radial load and axial load, high speed, the larger the contact angle, the higher the axial bearing capacity. Single row bearings can only bear the axial load in one direction, in radial load, will cause additional axial force. The axial displacement of the bearing can limit shaft or shell in one precision spindle bearings direction. If quality.the installation, the outer ring of a bearing on the relative, the wide end of the wide face, narrow end face with narrow end. So to avoid the additional axial force, but also in the two direction of the shaft or shell limit in the axial clearance range. Structural change of angular contact ball bearing as many as 70.
The 2.1 contact angle is 15 °, 25 °. 40 degrees three, the larger the contact angle of the axial bearing capacity is higher. High precision and high worm gear speed reducer speed bearings usually take 15 degrees contact angle, under the action of axial force, contact angle increases. The 2.2 is the inner or outer lock, inner, outer ring can not be separated. The outer ring and the inner ring heating after expansion, the rolling body, the holder assembly. Ball number ratio of deep groove ball bearing. Rated load in ball bearings in the largest, strong rigidity, smooth operation.
