1212 CT 60x110x22 Self Aligning Ball Bearing

What Is the 1212 CT 60x110x22 Bearing?

The 1212 CT 60x110x22 is a double-row self-aligning ball bearing designed to compensate for shaft misalignment while providing smooth and efficient rotational performance. Its spherical outer raceway allows the bearing to automatically accommodate angular misalignment caused by shaft deflection or housing inaccuracies, helping reduce internal stress and extend equipment service life.

With dimensions of 60 mm bore, 110 mm outside diameter, and 22 mm width, the 1212 CT bearing is widely used in industrial machinery, conveyors, pumps, fans, agricultural equipment and OEM applications where reliable operation and alignment flexibility are essential.

Design and Construction

The 1212 bearing features a proven self-aligning design developed for reliable operation under moderate radial loads and applications with shaft misalignment.

Main construction features include:

• Double-row ball bearing
• Self-aligning design
• Spherical outer raceway
• Cylindrical bore
• Open bearing construction
• Steel cage
• Low rolling friction

The self-aligning capability minimizes the effects of installation errors and shaft deflection, contributing to smoother machine operation.

How Does a Self Aligning Ball Bearing Work?

Unlike standard deep groove ball bearings, a self-aligning bearing has two rows of balls running on a common spherical outer raceway.

This design allows the bearing to:

• Compensate for shaft misalignment
• Reduce internal bearing stress
• Minimize vibration
• Improve rotational accuracy
• Extend bearing life
• Reduce wear on shafts and housings

It is especially beneficial where perfect shaft alignment cannot always be maintained.

Advantages of the Self Aligning Design

The 1212 CT bearing offers several engineering advantages:

• Automatic alignment compensation
• Smooth and quiet operation
• Low rolling resistance
• Reduced shaft loading
• Longer equipment service life
• Easy installation
• Reliable operation in industrial environments

These characteristics make self-aligning bearings suitable for numerous industrial applications.

Bearing Selection Guidelines

When selecting a bearing, engineers should consider:

• Shaft diameter
• Housing dimensions
• Bearing width
• Load type
• Rotational speed
• Lubrication method
• Operating environment
• Expected shaft misalignment

Selecting the correct bearing helps maximize machine reliability and operational life.
