Distinguish between INA universal joint bearing quality three methods and the use of choice

The size of the restrictions. INA bearings can usually install space is restricted. In most cases, the diameter of axle ( Or bearing inside diameter) Based on mechanical design or other design constraints. So bearing type and size of the choice is based on the universal joint of the inner diameter of the bearing. Thus, the main dimensions of the scale bearing table compiled by the diameter is according to the international scale. Scales the size of the bearing form is various, in machinery design is best used when scale bearing ( This design to the bearing is easy to purchase, just as an aside, here on some universal joint bearing catalogue models do have, but some non-standard bearings in mainland China there is no spot, futures will be a long time, sometimes to consider the time when INA bearing selection so the source of capital and the replacement of the late) Bearing load, the load on the bearing, the nature, size, direction is changeable. Usually, the basic load rating on dimension table are displayed. Axial load and radial load, and so on, but also important factors is to select a suitable bearing. When the size of the ball and needle bearing of proportion, needle roller bearing is usually have higher load capacity and bear the larger vibration and shock loads. Speed, promised to speed is according to INA bearing type, size, precision, cage type, load, lubrication, and cooling way. Universal joint bearing table lists the dimension precision bearings under oil lubrication and grease lubrication promised to speed. Usually, deep groove ball bearings, automatic self-aligning ball bearings and cylindrical roller bearings are used in high speed occasions. 1, through the surface of the bearing quality I found in the sales process of INA bearings many clients said that as long as the universal joint bearing surface brightness is of good quality, this is wrong. Light should be on the surface of the bearing is a kind of raven, of the cause of the raven is whether used in bearing steel standard and its cutting fluid used in the grinding process and etc, produced by the two before. 2, chamfering whether light bearing chamfer does not decide the quality of the bearing, but it reflects the universal joint bearing processing method. Chamfering is black, the heat treatment such as quenching, so increase the hardness of bearing, and some people think the chamfering is black not good-looking is not process completely, this is a myth. 3, one cage is better than two body, although the new process using one cage, but it is just to save material, and performance than the difference between the two bodies such as the rotary. In general, the service life of the universal joint bearing has relationship with three factors, one is the quality of the INA bearing itself. The second is using the environment. Three is to install method.
