Where This Is Used
- Automotive: Front wheel bearings, transmissions, differential pinion shaft.
- Electrical: High frequency motors.
- Industrial Equipment: Machine tool spindles, pumps, gas turbines, centrifugal separators, and Printing equipment.
Features
- Features Deep Groove Radial Bearing.
- The contact angle between the bearing balls and rings is normally 15, 30, or 40 degrees.
- The larger contact angle bearings have greater thrust load capacity.
- Single row bearings can accommodate radial load and axial load in one direction only.
- Double row matched bearings can accommodate radial load and axial load in either direction.
- The DT double tandem arrangement should be used for higher axial loads.
- Angular contact bearings can provide a high degree of accuracy and are capable of running at high speed.
- Cages can be pressed steel, machined copper alloy, molded polyamide, and machined synthetic resin.
