Spherical roller bearings: rolling body is convex or concave spherical roller tune heart to heart bearing. Convex spherical roller bearings, spherical outer ring has a raceway; there are concave roller bearings, the inner ring has a spherical raceway. Thrust roller bearings: rolling body is a roller thrust bearing. Thrust cylindrical roller bearings: rolling body is a cylindrical roller thrust bearing. Thrust tapered roller bearings: rolling body is tapered roller thrust bearing. Thrust needle roller bearings: rolling body is thrust needle roller bearing. Shun GF bearing warm remind customers, due to the bearing through anti-rust treatment and be packaged, and therefore can not not open the package just before installation. In addition, anti-rust coating on the bearing oil has good lubricating properties, for general purpose bearings or bearing grease filling can be used directly without washing. But for instrument bearing or bearings for high-speed rotation, application of clean rust oil cleaning oil will wash away the boards bearing, then the bearings easily rust, can not place a long time. Not by removing the check, you can identify or predict whether the operation of the bearing failure, to improve productivity and economy is very important. The main identification methods are as follows: 1) identification by voice recognition is required by sound experience. Must be able to identify adequate training to achieve the sound bearing and non-bearing sound. To this end bearing cheapest board should try to carry out this work by hand. Attached to the bearing shell can clearly hear the sound by listening or listening stick. 2) to identify the method by comparing the operating temperature belongs to identify the best method of circuit boards bearing manufacturers, is limited to use in the state do not change the operation of the occasion. Bearing low price board this end, the temperature must be continuously recorded. When a fault occurs, not only the temperature rises, there will be irregular changes. 3) to identify the state of the lubricant through the lubricant sampling and analysis, to judge whether the degree by which dirty foreign substance or metal powder. This method can not be close to the observed large bearing or bearings are particularly effective.
