Like (20000 CC) spherical roller bearing is what mean?
Spherical roller bearing with two rollers, mainly bear radial load, but also can withstand axial load in either direction. With high radial load capacity, especially for heavy load or vibration load, but can not withstand pure axial load. The raceway of the bearing outer race is spherical shape, so the self-aligning performance is good, and the coaxiality error can be compensated. Spherical roller bearing has two columns of 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. General allowed aligning angle is 1~2.5 degrees, the bearing capacity is large, 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 low working speed.
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 early production of spherical roller bearings can withstand axial load, the greater the operating temperature of the bearing 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 are without inner ring ribs and the use of steel stamping cage, the characteristics of CA type bearing inner ring for Trent on both sides of the wall and the used car business entity retainer in order to improve the bearing lubrication, can be provided to the user Spherical roller bearing for the outer ring 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, self-aligning roller bearings can also be provided with an inner hole taper, taper taper 1:12 the code for the 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, also with the help of compact sets or unloading sleeve bearings are mounted in a cylindrical shaft neckType CC is the most common type of small and medium self-aligning roller with retainer type, and is generally made of 08AL steel punching retainerLarge and extra large CAECAMB retainers are commonly used
