INA bearing heating and maintenance and lubrication knowledge - bearing

A lot of people want to learn some knowledge about the INA bearing, after all, China is now equipped with INA bearings of the mechanical equipment is very much, in the machinery industry to mix to master some knowledge of INA bearings technology is necessary. The following we will introduce INA bearings of knowledge. Causes of the INA bearing heating INA bearing installation askew, will cause the ball is not in the correct position of the bearing raceway rolling, and even cause larger ball end face and INA bearing inner race and the outer race against Taiwan axial force, bearing caused by overheating. Sometimes due to the size of the diameter of axle and bearing hole measurement inaccuracy or cooperate with surface roughness, do not meet the standard requirements to cause excessive interference fit, the bearing race is being squeezed from a large, leading to the INA bearing itself radial clearance is reduced, difficult to rotate the INA bearing, fever, wear or jammed, caused serious bearing inner and outer race during installation. INA bearing maintenance all INA bearing friction resistance of the bearing basically contains two hardened steel rings, multiple hardening of ball or roller, roller or roller and a separation or maintaining aircraft separation. These types are in use is divided into many types. Some types, such as bearings, needle column may not have the internal ring, roller directly on hardening axis movement. INA bearing lubrication in practice, it is necessary to use there is more than the recommended amount of grease. When the required torque low, only need a very small amount of grease lubrication of bearings will be finished. When the speed is very low and INA bearings exposure in dust or moisture, bearing may almost be filled. Bearing under the condition of high speed and high temperature usually need more frequent than in general lubrication.
