Self-Aligning Roller Bearing

A self-aligning roller bearing is a type of bearing with double row rollers, a shared spherical raceway on the outer ring, and two raceways on the inner ring that are inclined at a certain angle relative to the bearing axis. This design enables self-aligning roller bearings to have automatic self-aligning performance, which can adapt to angle errors caused by installation errors or shaft deflection, and is particularly suitable for situations that require bearing radial loads and bidirectional axial loads. There are two types of inner holes for self-aligning roller bearings: cylindrical and conical. The taper of the conical inner hole is usually 1:30 or 1:12. This design allows the bearing to be easily assembled on the optical axis or stepped machine shaft. Spherical roller bearings are widely used in fields such as papermaking machinery and speed reducers. Due to their ability to withstand large radial and bidirectional axial loads, as well as their excellent impact and vibration resistance, they are a very widely used type of bearing in the mechanical industry. ‌

The main characteristics of self-aligning roller bearings include:

Automatic self-aligning performance: Due to the spherical shape of the outer raceway, self-aligning roller bearings can automatically adjust the angle error caused by shaft or housing deflection, ensuring the normal operation of the bearing.

Enduring Heavy Load: Designed to withstand heavy radial loads and bidirectional axial loads, suitable for working environments with heavy loads or vibration loads.

Diverse structures: Spherical roller bearings have two types of structures: symmetrical spherical rollers and asymmetrical spherical rollers. The internal structure has been optimized to withstand greater axial loads and adapt to higher speed requirements.

Widely used: Widely used in various mechanical equipment in industries such as steel, mining, papermaking, shipbuilding, textile machinery, coal mills, and electricity, it is the most widely used type of bearing in the machinery industry.
