To fully meet with the bearing capacity and bearing (or thrust bearing shaft ring back ring) the entire circumference, must be fully supported by strong and uniform, bearing surfaces may be cylindrical or conical surface, the bearing shaft ring and ring, with a flat surface. Therefore, the surface of the bearing ring with the processing must reach a certain accuracy, and should not be any groove, hole or other discontinuous shape. In addition, the flange bearing ring must be securely fixed in order to prevent the load under the effect of the bearing ring in the rotation between the mating surface.
1, using the site: joint bearings for radial and axial load to accommodate radial loads, usually bearing two pairs to use, primarily in the car front and rear wheel, bevel gear, differential gear, reducer and other transmission parts.
2, allow the speed: in the installation of the correct, well lubricated environment, allowing for INA bearing limit speed of 0.3-0.5 times. Under normal circumstances, to 0.2 times the maximum speed is the most appropriate.
3, allow the tilt angle: flange bearings generally do not allow the tilt axis relative shell hole, if tilt is less than 2.
4, allowing the temperature: under the normal load, and the lubricant has high temperature resistance, and the full lubrication conditions, the general bearing allows the -30 C -150 C.
INA bearing removed after the intended to continue to use, should choose the appropriate removal tool. Interference with the demolition of the rings, can only increase tension in the ring, must not be allowed to pass through the rolling force demolition, otherwise the roller and the raceway will be crushed.
In general, it is necessary to have a suitable amount of interference, the bearing ring can be fixed in the radial direction and be enough to support. If the bearing ring is not correct or fully fixed, it is easy to cause damage to the flange bearing and related parts. But sometimes in order to facilitate the installation and removal, or INA bearings due to the floating end with the need to have the function of axial movement, you can not use the interference fit. In some cases the clearance fit, need to take some special measures to reduce peristalsis caused by wear, such as surface hardening bearing fitting surface and shoulder, with the surface through special lubricating oil to lubricate and remove the wear particles, or the use of locating key bearing side of the bearing is fixed.
