Product Description

The NSK 1205 is a double-row self-aligning ball bearing designed to automatically accommodate misalignment between the shaft and housing.

Self-Aligning Capability

• Outer ring has a spherical raceway
• Both rows of balls can pivot freely
• Misalignment does not cause high stress or reduce performance

Operating Characteristics

• Lowest friction among all rolling-element bearing types
• Low operating temperature even at high speed
• High radial load capacity
• Can handle light axial loads in both directions

This makes it ideal for applications where shaft deflection, assembly inaccuracy, or misalignment is present.

Typical Applications

• Electric motors
• Fans and blowers
• Agricultural machinery
• Conveyor systems
• Industrial equipment with shaft flex or alignment issues
• Textile machinery
