Precise double row angular contact ball bearing 5309 bearing

Advantages and disadvantages of double row angular contact ball bearings

Double-row angular contact ball bearings can withstand large radial and axial combined radial and axial loads and moment loads. They are mainly used in components that limit axial displacement of the shaft and the housing in both directions. For example: [SKF double row angular contact ball bearings are similar in design to two single row contact ball bearings arranged back to back, but the width is slightly narrower than two single row bearings. Compared with single-row bearings, it has better rigidity and can withstand overturning moment. The bearings are non-detachable. Particularly suitable for applications with high rigidity requirements.

It is widely used in the front wheel hubs of cars (some models also use double-row tapered roller bearings of the same size). Double-row angular contact ball bearings have limited tiltability between the inner and outer rings. The allowable tilt angle depends on the bearing's internal clearance, bearing size, internal design, and forces and moments acting on the bearing. No excessively high stress is generated in the bearing. If there is an inclination angle between the inner and outer rings of the bearing, it will affect the life of the bearing, and at the same time, the accuracy of the bearing will decrease, and the operating noise will increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing double row angular contact ball bearings, care should be taken. Although the bearing can withstand bidirectional axial loads, if there is a ball gap on one side, care should be taken not to let the main axial load pass through the groove side of the gap. When the bearing is used, care should be taken to make the raceway on the side without the ball notch bear the main load.
