spherical roller Bearing 22232
Designs and variants
Spherical roller bearings with two rows of rollers, which mainly bear radial
load, but also can withstand axial load in either direction. High radial load
capacity, especially suitable for heavy loads or vibration,but unable to bear
pure axial load. This kind of bearing outer ring raceway is spherical shape, so
its self-aligning performance is good, can compensate concentricity error.
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
bearing axis, with good aligning performance,when the axial force bending or
installation of the bearing can be normally used are not concentric, adjustable
mind with bearing sizesvary, the general allow aligning angle is 1~2.5 degrees,
the bearingload capacity is greater, the axial load can bear radial load
bearingcan bear bidirectional, with good impact resistance, generallyspherical
roller bearings are allowed to work low speed.
Spherical roller bearings are divided into symmetrical spherical roller and non
symmetrical spherical roller two different structure according to roller shape,
non symmetric spherical roller bearing is the early products, primarily for the
host computer repair service,the new design is rarely used host symmetrical
spherical roller bearings, through comprehensive improvement of internal
structureoptimization design and parameter, compared with the spherical roller
bearing early production, can bear axial load larger, the operating temperature
of the bearing is low, so it can adapt to highspeed requirements, according to
the inner ring without ribs and theholder is not the same can be divided into C
type and CA type two,C type bearings without inner ring rib and is use steel
stamping cage, characteristics of CA Trent bearing is on both sides of theinner
ring rib and car solid cage lubrication in order to improve thebearing, spherical
roller bearing outer ring to provide users withannular oil groove and three oil
hole, the bearing rear code /W33 said, according to the requirements of the
user can also supplyspherical roller bearings with inner ring oil hole, in order to
facilitatecustomer handling and replacement of bearings, self-aligning roller bearing
shaft can be provided with a taper hole of the bearing,taper taper After
the 1:12 named K said, in order to meet the special requirements of users can
also provide hole taper of 1:30bearing, the rear code for K30 bore tapered
bearing lock nutbearing can be mounted directly on the tapered shaft neck, or
with the help of compact sets or unloading sleeve will bearing installationin the
cylindrical shaft neck
Factors that influence spherical roller bearing performance
Bearing performance is not only determined by load or speed ratings. There
are a number of other factors that contribute to bearing performance. To a
large extent, performance is influenced by the geometry of the rollers,
raceways and cages, the heat treatment, as well as the surface finish of all
contact surfaces.
Main factors which influence spherical roller bearing performance include,
but are not limited to:
1.Symmetrical rollers
Symmetrical rollers self-adjust, providing optimal load distribution along the
roller length. This keeps stresses low under all load conditions and extends
bearing service life.
2.Roller tolerances
The rollers in an spherical roller bearing are manufactured to extremely
tight tolerances for dimension and form. Each roller is virtually identical in size
and shape to the other rollers in the set. This optimizes load distribution over
the rollers to maximize bearing service life.
3.Special roller profile
The roller profile determines the stress distribution in the roller/raceway
contact area. The special profile distributes loads more evenly along the
rollers and prevents stress peaks at the roller ends to extend bearing service life.
