Name£ºSpherical Roller Bearing
Introduction£º
Spherical Roller Bearing
Details£º
Spherical roller bearings are principally provided with two rows of symmetrical spherical rollers and a common sphere raceway in outer ring. The two inner ring raceways are inclined at an angle to the bearing axis. This type of bearings has good self-aligning ability. The permissible aligning angle is 1-2.5¡ãfor shaft deflection under load or shaft misalignment in mounting. These bearings have heavy load carrying capacity and anti-impact ability. In addition to radial load, they also can carry axial load in two directions. In general, this type of bearings permits a lower limiting speed.

LEGEND spherical roller bearings have two designs depending on the shape of roller cross section, symmetrical rollers and asymmetrical rollers. Asymmetrical roller bearings are the earlier products and now are seldom to use, but they are used for the machine maintenance. Compared with the earlier products, internal designs of symmetrical roller bearings have been improved and the parameters have been optimized. Therefore, they are particularly suitable for carrying heavier axial load and their operating temperature is lower, so they can rotate at higher speed.

LEGEND spherical roller bearings are divided into types C and CA depending on the design of the bearing structures. Type C bearings have a flangeless inner ring and a pressed steel cage, and type CA bearings have a double ribbed inner ring and a machined solid cage.

In order to lubricate bearings efficiently, spherical roller bearings with an annular groove and three oil holes in the outer ring can be provided by LEGEND. Bearings with this feature are suffixed with W33. According to the requirements of customers, spherical roller bearings with lubricating oil hole in the inner ring can also be supplied by LEGEND.

For ease of dismounting and replacing bearings, bearings with tapered bore can be provided with bore taper 1:12, and they are identified by suffix K. To satisfy special requirements, bearings with bore taper 1:30 will be supplied, and they are suffixed with K30. Bearings with tapered bore can be directly mounted on tapered journal by using locking nut, or can be mounted on cylindrical shaft with tapered adapter or withdrawal sleeve.
