Spherical roller braring

Spherical roller bearing is a type of bearing with two rows of drum-shaped rollers, in the middle of the inner ring there are two rolling faces and the outer ring has two rows of rollers. a spherical roller. The center of the outer ring groove surface coincides with the bearing center. The two grooves of the innermost ring are inclined at an angle to the bearing shaft. Bearings can automatically adjust center, so they have the ability to choose not easily misaligned. In addition to its very large radial load capacity, it can also withstand axial loads in both directions. In addition, HRB spherical roller bearings are equipped with a large number of long and symmetrical large diameter rollers that can withstand extreme loads. Compared with traditional spherical roller bearings, these bearings have lower operating temperatures, can handle heavier axial loads, or can achieve higher speeds. They are the frequent choice of very high load applications in large devices.

This type of bearing can have a taper hole and can be mounted directly on a tapered or cylindrical shaft using a sleeve (taper bush).</p >

The spacer is usually machined in monolithic copper, molded from polyamide or made from stamped steel.

The international symbol for drum bearings usually has 5 main digits, starting from 2.
