24122CA / W33

Description

The aligning roller bearing has two rows of rollers, one shared spherical
raceway in the outer ring and two raceways in the inner ring and is inclined to
an Angle relative to the bearing axis. This clever structure makes it with
automatic aligning performance, so it is not easy to be affected by the Angle
of shaft and bearing box seat on the error or shaft bending, suitable for
installation error or shaft deflection caused by Angle error occasions. The
bearing can bear not only radial load, but also two-way axial load.



Structure

Spherical roller bearings with tapered bore bore with the rear code K and K30
installed on the matching adapter sleeve become rear code K+H type and K30+H
type bearings. These bearings can be mounted on a smooth shaft without a
shoulder and are suitable for applications where the bearing needs to be
mounted and dismounted frequently. In order to improve the lubrication
performance of the bearing, there are annular oil grooves in the outer ring of
the bearing and three evenly distributed oil holes are drilled, the post-code
is W33.

Advantages

1. The radial load capacity is large. Easy to install, can be installed
directly or use the tight sleeve, assembly cylinder installed on the
cylindrical shaft.

2. Can bear a certain axial load. The outer ring raceway of this kind of
bearing is spherical and can bear large radial load. Therefore, it has the
aligning performance, which is not affected by the misalignment of shaft and
bearing box or shaft deformation and deflection, and can compensate the
coaxiality error.

3. With two rows of spherical rollers, the outer ring has a common concave
spherical raceway, the inner ring has two concave raceway inclined to an Angle
with the bearing axis, the center of curvature of the outer ring raceway is
consistent with the bearing center.

4. In addition to bear radial load, but also can bear two-way axial load and
its combined load. The bearing capacity is large, and it has good vibration
resistance and impact resistance.
5. The roller can be adjusted freely in the spherical raceway in the outer
ring, so that the shaft deformation and the misalignment error of the bearing
seat can be compensated. This kind of bearing combines the characteristics of a
variety of design, in many cases, can not be completely replaced. The number,
length and diameter of rollers in the centering roller bearings are the maximum
allowable values for the structure. The close contact between the raceway and
the roller ensures the uniform stress distribution and makes the bearing have
high bearing capacity.
6. Due to the unique internal design of spherical roller bearings, they can
bear very heavy axial loads, even pure axial loads.

How to Install Spherical Roller Bearing?

Spherical roller bearings are bearings equipped with drum rollers between the
inner ring with two raceways and the outer ring with spherical raceways. The
center of curvature of the raceway surface of the outer ring is the same as the
center of the bearing, so it has the same aligning function as self-aligning
ball bearings. When the shaft and housing are deflected, the load can be
automatically adjusted and the axial load in both directions can be adjusted.
Large radial load capacity, suitable for heavy load and shock load. Bearings
with an inner diameter of the inner ring are tapered bores and can be mounted
directly. Or use the adapter sleeve, disassembly cylinder to install on the
cylindrical shaft. The cage uses steel stamped cage, polyamide formed cage and
copper alloy turning cage.

For self-aligning bearings, the use of an intermediate mounting ring prevents
the outer ring from tilting and rotating when loading bearings with shafts into
the housing shaft bore. It should be remembered that the balls of some sizes of
self-aligning ball bearings protrude from the sides of the bearing, so the
middle mounting ring should be recessed to prevent damage to the balls. A large
number of bearings are generally mounted mechanically or hydraulically press-
in.

For separable bearings, the inner and outer rings can be mounted separately,
which simplifies mounting, especially if both the inner and outer rings require
an interference fit. When fitting a shaft with the inner ring in place into a
bearing housing with the outer ring, care must be taken to see that the inner
and outer rings are properly aligned to avoid scratching the bearing raceways
and rolling elements. If cylindrical and needle roller bearings have an inner
ring without flanged flange or an inner ring with a flange side on one side, a
mounting sleeve is recommended. The outer diameter of the sleeve should be
equal to the inner ring raceway diameter F, and the tolerance standard for
machining should be d10. Stamped outer ring needle roller bearings are best
mounted with a mandrel shaft.

Universal Failure Modes

1. The bearing is damaged when the aligning Angle is exceeded during
installation.

2. When installing the bearing inner ring with the press, avoid the support
under the outer ring to prevent the installation of the bearing when the
bearing is pressed down, resulting in the crushing of the outer ring edge.

3. The installation axial was preloaded which causes damage to the aligning
roller bearing.

4. Fracture of inner ring caused by large installation interference.

5. Poor lubrication leads to early wear of bearing raceway.
