GJP Wheel Double Row Angular Contact Ball Bearing DAC42800042

Description- GJP Double Row Angular Contact Ball Bearing DAC42800042(Size42x80x42mm)

GJP Bar Code Number: 6935329839335

GJP first general automotive bearing is made of double row angular contact ball bearing, which has one outer ring and one split inner race, its widely used on all type of automotive rear axle, and helps the wheel reduce the friction and have better rotation, it’s double row structure benefits for bigger loading capacity when your automotive is running time to time, because of it’s easy design, when install this wheel bearing into the hub or the knukle, it requires better equipment and advanced technology, this item has the size of 42 bore, 80mm outer diameter and 42mm width, and the application car model is Volkswagon TRANSPORTER III Bus, TRANSPORTER III Flatbed / Chassis, Porsche 944, BMW 730 etc.

GJP advantage

1. Using bearing dynamic simulation analysis could tell the internal stress of the bearing and optimize the bearing design dimensions. With this method we can design bearings and control the bearing internal stress below 2000MPa and avoid early failures.
2. Guiding by the simulation software, can find a better bearing pre-tightening force to mount the bearing on a car.
3. Guiding by the simulation software, can optimize the bearing design and prolong the bearing life 15~20% better.
4. Analysis the bearing life with dynamic simulation software could shorten our sample design and develop period in 60 days.

The design of double row angular contact ball bearings is basically the same as that of single row angular contact ball bearings, but only takes up less axial space. Double row angular contact ball bearings can withstand radial loads and axial loads acting in two directions, it can limit the bidirectional axial displacement of the shaft or housing, and the contact angle is 30 degrees. High rigidity bearing arrangements are available and can withstand overturning moments.

Scope of application of  double row angular contact ball bearing

Compared with single row angular contact ball bearings, double row angular contact ball bearings have better rigidity and can withstand overturning moments. Bearings are non-separable. Especially 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).

Performance characteristics of double row angular contact ball bearing

The tiltability between the inner and outer rings of a double row angular contact ball bearing is limited. The allowable tilt angle depends on the internal clearance of the bearing, bearing size, internal design and the force and moment acting on the bearing. The maximum allowable tilt angle should be guaranteed Excessive additional stress is not generated in the bearing.

If there is an inclination angle between the inner and outer rings of the bearing, the service life of the bearing will be affected, and at the same time, the running accuracy of the bearing will decrease and the running noise will increase. Double row angular contact ball bearings generally use nylon cages or brass solid cages. When installing the double row angular contact ball bearing, it should be noted that although the bearing can bear bidirectional axial load, if there is a gap for the ball on one side, care should be taken not to let the main axial load pass through the groove on the side with the gap. When the bearing is used, care should be taken to make the raceway on the side without the ball-loading notch bear the main load
