1307 ETN9: Self-Aligning Ball Bearing

Self-aligning ball bearing with extended inner ring

Self-aligning ball bearings, with extended inner ring, 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 insensitive to angular misalignment of the shaft relative to the housing. The extended inner ring enables use of commercial grade shafting and axially location on the shaft by means of a slot at one end of the inner ring.

• Accommodate static and dynamic misalignment
• Excellent high-speed performance
• Excellent light load performance
• Low friction
• Extended inner ring facilitates ease of mounting
