What Is The Features of Motorcycle Bearings ? Firstly,the motorcycle bearing raw materials are with corrosion resistance. Secondly, to analyze the operating characteristics of motorcycle bearing specifications, because in the production process, it is necessary to maintain the operating conditions for a long time, so the common raw materials need to have certain wear resistance and high-quality ab...

We will choose bearing grease according to bearings working conditions such as speed, operating temperature, load, etc. If there are no special requirements, lithium-based grease or molybdenum disulfide grease is generally used to meet the needs. If there are special requirements, such as high temperature resistance, low temperature resistance, high load, high speed, high load, it is recommended t...

ZZ bearing means that it has metallic shields (yellow metal shield) on both the sides. With ZZ bearings ,bearings can long working life .because it can protect bearings far away from dust,and outside impurities go into bearing inside . We also have 2RS bearing (rubber seals ) You can choose what you need .

C codes for degree of bearing clearance The C code of bearings at the rear follows the complete coding. Here you will find all the characteristics of the bearings in terms of material, lubrication and therefore also the degree of internal bearing clearance. These are the 5 most common C codes for internal bearing play: C1, C2, C3, C4 and C5. If a bearing has a C code, it offers extra internal clea...

The main causes of bearing corrosion: 1. Metal surface  (corrosion of batteries with poor oxygen concentration). 2. The chemical composition and structure of the metal material itself. 3. The composition and pH value of the solution in contact with the metal surface. 4. Ambient temperature and humidity. 5. Various environmental media in contact with the metal surface. 6. Human sweat is also t...

The pillow block bearings are consist with Chrome steel Gcr15 insert ball bearing and cast  iron bearing unit . The internal structure of the pillow block bearings are the same as the deep groove ball bearing, but the inner ring of this bearing is wider than the outer ring. The outer ring has a truncated spherical outer surface, which can be automatically aligned with the concave spherical su...
