Bearing alloy corrosion general area for lubricants impure, lubricants in the chemical impurities (acidic oxide, etc.) of the bearing alloy oxidation and produce acidic substances, causing the bearing alloy par ts fall off, forming irregular tiny hole or small concave pit. The bearing alloy corrosion mainly due to improper selection of lubricant, bearing materials and corrosion resistance, or the operation of the engine and crude, the temperature is too high. big ball bearing
All bearings in the anti-friction bearings are basically contains two hardened steel ring, a plurality of hardened balls or rollers, as well as a separation of the separation of the rollers or the roller frame or holder. These types in use is divided into many types. Some types, such as bearings, needle column may not be the inner ring, the rollers directly hardened shaft movement.
In practice it is necessary to use more than the recommended amount of grease is yes. Only need very little grease can be done when the required torque is low, the lubrication of the bearing. Very low speed and bearing exposed to dust or moisture in the bearings m ight almost be filled. Bearings in high-speed and high-temperature conditions require more frequent lubrication is usually higher than the general case. grinding spindle
