Oil seal commonly used materials are: nitrile rubber, fluorine rubber, silicone rubber, acrylic rubber, polyurethane, ptfe and so on. NBR nitrile rubber (NBR) It has good heat resistance, wear resistance, resistance to all kinds of lubricat...
1, be sure to install correctly Improper installation will greatly shorten the service life of self-lubricating bearings. This is almost universally understood, so do not easily try to install their own, should be by professional technical...
The advantages of self-lubricating bearings (oil-free bearings), most of the bearings used in various machinery industries are ball bearings, needle rolls and so on, but a small part of the use of self-lubricating bearings, I believe that i...
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...
