Bearings must be installed in the dry、Carried out under clean environmental conditions。The mating surface of the shaft and housing should be carefully checked before installation、Convex shoulder end face、Machining quality of grooves and joint surfaces。All mating surfaces must be carefully cleaned and burrs removed，The raw surface of the casting must be cleaned of molding sand。
Butter the cylinder pad when installing it Some repairmen install cylinder gaskets，Likes to put a layer of butter on the cylinder pad，It is thought that this will increase the tightness of the engine。Hardly realize，This is not only unhelpful，Rather harmful。
First of all，Spindle bearing in spindle when running,To ensure adequate lubrication，And according to the actual use of regular lubricating oil，Do not cut off oil for a long time。therefore，For the user enterprise，Should choose better、More suitable spindle oil。
In order to maintain the bearings original performance in good condition for as long as possible，Must be maintained、overhaul、To prevent accidents before they happen，Ensure the reliability of operation，Increase productivity、economy。
CAD/CAMThe system already plays an important role in many ways，This paper combines the development practice of tooling management system of Wafangdian Bearing Co., LTD，The general structure of the system and the entry of the tooling list are emphasized、search、edit、printout、Version management、The realization of electronic signature and other functions，It is hoped that comrades who carry out similar development work can play a reference role。
In order to enableNSKThe service life of bearings is longer，We are going to share it with you todayNSKBearings use life cycle extension methods，I hope you can help

For using bearings，Making noise is quite common。Even ifNSKThe same is true of low-noise bearings in bearings。In that way，Why the noise
Industrially developed countries as early as20In the 1960s and 1970s, push-rod and roll-bottom isothermal spheroidizing annealing furnaces were fully promoted，Shorten annealing cycle，Save energy，Improve annealing quality。With the development of bearing parts processing technology，Precision forging and precision rolling(Cold forging)Process adoption，The machining precision of parts blank is getting higher and higher，Gradually promote less and no turning technology，This brings the demand for protective atmosphere annealing。
Does not pass disassembly inspection，It can identify or predict the bearing failure in operation，It is very important to improve productivity and economy。
