22315 22316 22317 CA/C3W33 Brass Cage Spherical Roller Bearings

The Self-Aligning Roller Bearing Has A Double Row Of Rollers, The Outer Ring Has A Common Spherical Raceway, The Inner Ring Has Two Raceways And Is Tilted At An Angle Relative To The Bearing Axis. This Clever Structure Makes It Have Automatic Aligning Performance, So It Is Not Easy To Be Affected By The Angle Of Shaft And Bearing Box Seat On The Error Or Shaft Bending, And Is Suitable For Installation Error Or Shaft Deflection Caused By Angle Error Occasions. In Addition To The Radial Load, The Bearing Can Also Bear The Axial Load Of Bidirectional Action.

Self-Aligning Roller Bearings Are Divided Into Two Different Structures According To The Roller Cross Section Shape: Symmetrical Spherical Roller Bearings And Asymmetric Spherical Roller Bearings. Asymmetric Self-Aligning Roller Bearings Are Early Products, Mainly For The Maintenance Service Of The Main Engine. When Designing The New Main Engine, Symmetrical Self-Aligning Roller Bearings Are Rarely Used. It Can Withstand Greater Axial Load, And The Operating Temperature Of This Bearing Is Lower, So It Can Adapt To The Requirements Of Higher Speed
