Spherical roller bearing with two rollers, mainly bear radial load, but also can withstand axial load in either direction. It has high radial load capacity, especially for heavy load or vibration load, but can not bear pure axial load. The outer raceway of this kind of bearing is spherical, so it has good center performance and can compensate the error of coaxiality.
There are two symmetrical spherical roller, the outer ring has a common spherical raceway, inner ring with two raceways inclined at an angle with the axis of the bearing, has good aligning performance, the axial force bending or the installation of the bearing can be used not concentric, concentric tone with the size of bearing series vary, generally allow the aligning angle of 1~2.5 degrees, the bearing load capacity is larger, the axial load can bear radial load and the outer bearing can bear bidirectional effects, has good anti impact ability, general spherical roller bearings allow working speed is low.
Spherical roller bearing is divided into symmetrical and non symmetrical spherical roller spherical roller two different structure according to roller shape, non symmetrical spherical roller bearing is the early products, mainly for the host service, the new design is rarely used host symmetrical spherical roller bearing, through the comprehensive improvement of internal structure design and parameter optimization, compared with the spherical roller bearing early production, able to withstand greater axial load, the bearing operating temperature is low, so it can adapt to high speed requirements, according to the inner ring without ribs and the cage can be divided into C type and CA type two, C type bearings without inner ring ribs and is made of steel plate stamping cage, CA type bearings for Trent on both sides of the wall and the inner used car business entity retainer in order to improve the bearing lubrication, the outer ring can provide to the user Spherical roller bearing with an annular oil groove and three oil holes, the bearing post code /W33 said, according to the requirements of users can also supply roller bearings with inner ring oil hole, in order to facilitate customer handling and replacement of bearings, roller bearing bearings can also provide inner hole with taper hole, the taper of 1:12 after the code K said, in order to meet the special requirements of users are also available in the taper hole of 1:30 bearing, the rear code for K30 hole taper bearing locking nut bearing can be mounted directly on the tapered shaft neck, or with the help of compact sets or unloading sleeve bearings are mounted on the cylindrical shaft neck.
