Self-aligning ball bearings

Self-aligning ball bearings have two rows of balls, a common sphered raceway in the outer ring and two deep uninterrupted raceway grooves in the inner ring.
They are available open or sealed. The Aligning bearing are insensitive to angular misalignment of the shaft relative to the housing , which can be caused, for example, by shaft deflection.
By the two tracks of the inner ring and the raceway for the spherical surface between the outer ring, assembled with a round ball ball bearing Aligning bearing Spherical ball bearings have cylindrical hole and tapered hole two kinds of structure, the material of cage has steel plate, synthetic resin, etc..
Its characteristic is that the outer ring raceway is spherical, with self-aligning, can compensate for the error caused by different heart and shaft deflection, but its inner and outer ring relative tilt shall not exceed 3 degrees Aligning bearing.

Features and Benefits

Accommodate static and dynamic misalignment
The Aligning bearing are self-aligning like spherical roller bearings or CARB bearings.
Excellent high-speed performance
Aligning bearing generate less friction than any other type of rolling bearing, which enables them to run cooler even at high speeds.
Minimum maintenance
Because of low heat generation, the bearing temperature is lower, leading to extended bearing life and maintenance intervals.
Low friction
Very loose conformity between balls and outer ring keeps friction and frictional heat at low levels.
Excellent light load performance
Self-aligning ball bearings have low minimum load requirements.
Low noise
Self-aligning ball bearings can reduce noise and vibration levels, for example, in fans.

Applications

Self-aligning ball bearings are suitable for bearing heavy loads and impact loads,
precision instruments, low-noise motors, automobiles, motorcycles, metallurgy, rolling mills, mining, petroleum,
paper, cement, sugar and other industries and general machinery, etc.

FAQ

What are radial and axial loads?

Loads are defined by their direction. Loads perpendicular to the shaft are called radial loads and loads parallel to the shaft are called axial (thrust) loads.

What is the difference between deep groove ball bearings (DGBB) and angular contact ball bearings?

DGBB can carry axial loads in both directions, whereas angular contact ball bearings can only carry axial loads in one direction.

What is the difference between open, sealed and shielded deep groove ball bearings?

Seals and shields provide additional protection for the bearing components and help to improve and maintain lubrication.
In terms of sealing performance, sealed bearings rank best, followed by shielded bearings and finally open bearings.

What is the right deep groove ball bearing for your machine?

Deep groove ball bearings are available in a large number of sizes with different seals, shields, cages, and greases.

How to mount and dismount your bearing?

Successful mounting is critical to the life cycle of your bearing. Proper bearing dismounting can safeguard other machine components and maintenance workers.

Bearing failure and how to prevent it

The bearing is at the heart of all rotating equipment, and the condition of the bearing often reflects how well a machine is running.
