Advantage of 7020C Bearing
When using the bearing, pay attention to make the raceway on one side without ball loading notch bear the main load.The locking port of this kind of bearing is on the outer ring.
Generally, the inner and outer rings cannot be separated, and can bear the combined radial and axial load and the axial load in one direction.
The ability to bear axial load is determined by the contact angle.
The larger the contact angle, the higher the ability to bear axial load.
Angular contact ball bearings are mainly divided into single row angular contact ball bearings and double row angular contact ball bearings.
1.Single row angular contact ball bearings can only bear axial load in one direction, and will cause additional axial force when bearing radial load. And can only limit the axial displacement of the shaft or housing in one direction.
2.f it is installed in pairs, make the outer rings of a pair of bearings face each other, that is, the wide end faces the wide end face, and the narrow end faces the narrow end face. This avoids causing additional axial forces and confines the shaft or housing to the axial play in both directions.
3.Double row angular contact ball bearings can bear the combined load of radial and axial loads at the same time,
(Single row angular contact ball bearings can only bear axial load in one direction, so they are generally installed in pairs) to limit the axial displacement of the shaft on both sides.
4.The axial displacement occurs because of the existence of the inclination angle between the inner and outer rings of the double row angular contact ball bearing
What factors does the existence of the inclination angle depend on?
5.The internal clearance of the bearing, the bearing size, the internal design and the forces and moments acting on the bearing, and the maximum allowable inclination angle should ensure that excessive additional stress will not be generated in the bearing.
6.What are the effects of the presence of a tilt angle? It affects the life of the bearing, and at the same time causes the bearing running accuracy to decrease and the running noise to increase (the additional stress of the bearing).
7.Therefore, the maximum allowable inclination angle should ensure that excessive additional stress will not be generated in the bearing.
