What is the function of spherical roller bearings?

The models of spherical roller bearings are spherical roller bearings (type 20000CC), spherical roller bearings with tapered bore (type 20000CCK), spherical roller bearings (type 20000CC/W33), spherical roller bearings with tapered bore (type 20000CCK/W33), spherical roller bearings mounted on sleeve (type 20000CCK+H) spherical roller bearings mounted on sleeve (type 20000CCK/W33+H). There are a total of 6 types. Here let us read the following words and know more about the spherical roller bearings.

What are the advantages of spherical roller bearings?

1. Conventional spherical roller bearings have asymmetrical rollers that generate an axial force component during operation. The rollers are influenced by this force component and touch the central solid rib. The setting of symmetrical rollers. spherical roller bearings that use a movable component axially movable roller intermediate ring, whereby the rollers are no longer constrained by the central retaining edge, the undercut groove of the inner ring raceway is eliminated, and longer rollers can be used, thereby improving the load bearing capacity.

2. The contact angle of the single row spherical roller bearing is 0, and the contact angle does not change significantly under axial load. A small axial load creates a large contact force between the roller and the raceway. With axial load relatively greater than the radial load, the single row spherical roller bearing cannot bear the combined radial and axial load.

3. Similar to the spherical ball bearing, the double row spherical roller bearing with clamping sleeve can be installed anywhere on the optical axis without machining the positioning shoulder.

What is the difference do you know between using spherical roller bearings and spherical ball bearings?

1. Low speed and heavy load conditions, suitable for spherical roller bearings

2. High speed and light load conditions, suitable for spherical ball bearings

What kind of spherical roller bearing should we choose?

Wear resistance

When the spherical roller bearing is working, not only rolling friction occurs between the ring, rolling element and cage, but also sliding friction, so that the bearing parts are constantly worn out. To reduce the wear of bearing parts, maintain the stability of bearing accuracy and extend the service life, bearing steel should have good wear resistance.

Contact strength

Under cyclic load, the contact surface of the bearing is prone to fatigue damage, i.e. cracks and chipping, which is the main form of bearing damage. The steel used in the spherical roller bearing must have a high contact fatigue strength.
