A self-aligning bearing with a tapered bore is a specialized type of rolling bearing designed to accommodate both misalignment and tapered shaft mounting.

A self-aligning bearing has an inner ring with two rows of balls and a common spherical outer raceway in the outer ring. This allows the bearing to automatically compensate for shaft misalignment or deflections.

Key Features:

• Automatic alignment in case of shaft deflection or housing misalignment.
• Typically used in applications where alignment is difficult to maintain.
• Common types: Self-aligning ball bearings and self-aligning roller bearings (spherical roller bearings).

Applications

• Electric motors
• Conveyors
• Pumps
• Agricultural machinery
• Fans and blowers
