- Introduction： THE INSTALLATION OF THE SLIDING BUSHING AND THE HOUSING
- Physical and mechanical properties:
The lnstaallation of SF Bush
SF bushes should de cleaned in kerosene or diesel oil first, immersed in engine oil and then dried up. When the bush is installed into housing, make sure the bush not rotating in thehousing or moving in the axial direction and at the same time make the outer surface fully contact to the base hole, generally guarantee the contact area over 70%,thus to improve load capacity and transmission of friction heat. The inner surface steel backing.The friction coefficient of steel to steel is bigger that of steel to plastic. So we should choose the lightgraded tight fit, preventing the axle sleeve from moving in the base when working, and also preventing the inner holes from getting deformed and too big because of the large tight fit of the outer diameter.
Out circle of the axle sleeve should be avoided in the high-pressure working conditions. Two methods are recommended here.:
1、increase the outer dia meter of the axle sleeve, and the deformation of inner holes can be calibrated with calibrating core stick
2、When installing, apply ZY 801 Oxygen-hatred glue in the housing to streng then the combination strength between the axle sleeve and base hole. For bush (outer diameter＜55mm),press the bush into the hous- ing gently and carefully using an core axle with a handle. Fig A. For bush (outer dimeter＞55mm), press the bush into the hous- ing gently and carefully using a handle with a shoulder, an "O" ring and an assisting circle. Fig B.
