Self-Aligning Ball Bearing (2311 K) This type of ball bearing is recommended when alignment of the shaft and housing is difficult and the shaft may flex. The outer ring has a spherical raceway and its centre of curvature coincides with that of the bearing; Therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. Pressed steel and polyamide cages are available. Since the contact angle is small, the axial load capacity is low. The permissible dynamic misalignment is approximately 0.07 to 0.12 radian (4 to 7 degrees) under normal loads. Product Features and Benefits: A: High quality Steel - Ultra clean steel to extend bearing life by up to 80%. B: Advanced Grease Technology - NSK lubricants that can extend grease life and performance. C: High Grade Balls - Quiet and smooth operation even at high speed. Super Finished Raceways - Specially honed to minimise noise and improve lubricant distribution and life. D: Sealed versions available Inquiry: 1).
