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 Crossed Roller Slewing Bearing of the bearing can limit shaft or shell in one 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 Full complement cylindrical roller bearings contact angle is 15 °, 25 °. 40 degrees three, the larger the contact angle of the axial bearing capacity is higher. High precision and high 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.
2.3 can use inner, outer mutual displacement adjustment radial clearance. Often used in pairs, and applying a pre load, in order to improve the bearing stiffness.
3, cylindrical roller bearings
3.1 roller and raceway for slewing rings the line of contact, radial load capacity, suitable for heavy load and shock load.
3.2 the friction coefficient is small, suitable for high-speed, the speed limit is close to the deep groove ball bearing.
