Self-aligning ball bearings can withstand a larger radial load, but
also can withstand a certain axial load. This type of bearing outer
ring raceway
It is a spherical shape, it has self-aligning properties when the
axis bending or tilt the inner ring and the centerline of the outer
ring inner ring relative tilt does not exceed 1 ° ~ 2.5 °, the
bearings can work.
Self-aligning ball bearings bore cylindrical and conical two.
Cone-shaped hole in the taper of 1: 1 2 or 1:30. In order to
strengthen the bearing lubrication performance, in the bearing
outer ring on the processing of an annular oil tank and three oil
holes are evenly distributed.

Spherical Roller Bearing Information:
(Universal Series 12xx, 13xx, 22xx, 23xx)
1. Roller bearings use rolling elements to maintain the separation
between moving parts to reduce rotational friction and support
radial and axial loads.
These elements can be one of the following types: ball,
cylindrical, spherical, barrel, needle, spindle, or tapered.
2. All roller bearings are open, shielded, or sealed.
3. Sealed bearings are lubricated with oil or grease in the bearing
factory, while open and shielded bearings are meant to be
lubricated in place, with periodic reapplication of lubrication,
based on use.
4. The shield protects the working parts of the bearing from
environmental debris that may be introduced and could reduce the
ball bearing speed and lifespan.
5. This structure of type is Cylindrical and tapered holes.
Advantage:
1. Easily compensate for the error of the heart ball bearing by
different degrees of heart and shaft deflection.
2. Radial loads while also withstanding certain axial loads
3. Large temperature range
Application:
Suitable for precision instruments, low noise motors, automobiles,
motorcycles, and general machinery, etc. It is the most widely used
type of bearing in the machinery industry.
