FREQUENT Q/A
Plastic coated bearings generally refer to a layer of plastic on the outer surface of the bearing. The plastic material is generally nylon PA, polyformaldehyde POM and engineering plastics polypropylene and PP. The outer plastic has certain...
Flange bearings mainly bear radial loads, but also bear radial and axial loads at the same time. But for the life of flange bearings are not very well understood, the following three measures to extend the life of bearings: (1) In order to...
Method one: open the window to listen to whether the sound comes from outside the car; Method two: after improving the speed (when the buzz is larger) will gear in neutral to let the vehicle taxi, observe whether the noise comes from the en...
Hub bearing (hub bearing) is the main role of bearing and provide accurate guidance for the rotation of the hub, it bears both axial load and radial load, is a very important part of the traditional car wheel with bearings is composed of tw...
The method of distinguishing high-speed bearings and low-speed bearings is as follows :1. It's different from the rotational speed. 2. Differentiate by appearance. 3. Separate from the material. 4. Separate from the end. ...
1. Precision plastic bearings Precision plastic bearing, compared with traditional plastic bearing precision and tolerance improved. The inner and outer rings, rolling body and cage are generally made of materials suitable for precision mac...
Advantages of plastic bearings 1. Plastic bearings as a whole are lubricating materials with long service life. 2, plastic bearings will not rust in the application and corrosion resistance, and metal materials bearing rust can not be used...

The function of thrust bearing is to bear the axial thrust of rotor in operation, and to determine and maintain the axial mutual position between turbine rotor and cylinder. Thrust bearing can be set as a separate type, but also can be comb...
The fit of thrust bearing and shaft is generally transition fit, and the fit of seat ring and bearing seat hole is generally clearance fit. The middle shaft ring of bi-directional thrust bearing should be fixed on the shaft to prevent rotat...
