NACHI Angular contact ball bearing

Nachi angular contact ball bearing can bear radial load and axial load at the same time. The higher the speed, the greater the contact angle, the higher the axial bearing capacity

single row bearings can only bear axial load in one direction, which will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction

If Nachi angular contact bearings are installed in pairs, make the outer rings of a pair of bearings opposite, that is, wide end face to wide end face, and narrow end face to narrow end face. In this way, additional axial force can be avoided, and the shaft or housing can be limited to the axial clearance in both directions

secondly, there are three nominal contact angles: 15 °, 25 ° and 40 °. The larger the Nachi contact angle, the higher the axial bearing capacity. High precision and high-speed bearings usually take 15 ° contact angle, which will increase under the action of axial force. At present, there are more than 70 variant structures of angular contact ball bearings

generally, the inner ring or outer ring is provided with a locking port, and the inner and outer rings cannot be separated. The outer ring is assembled with the inner ring, rolling element and cage assembly after heating and expansion. The number of balls installed is more than that of deep groove ball bearings. The rated load is the largest among ball bearings, with strong rigidity and stable operation. The radial clearance can be adjusted by the mutual displacement of the inner and outer rings. It is often used in pairs and preloaded to improve the rigidity of Nachi bearings< br>
