NBR'S Advantages:
NBR is the wildly used oil resistance compound nowadays. It has a
great resistance to wear. The –CN contains in Acrylonitrile can
affect physical characteristics other than oil resistance. The
higher the Acrylonitrile content, the better the resistance to oil.
However, the lower the acrylonitrile content, the better the
resistance to low temperature. NBR is used at temperature between
-25°C~100°C. The life time of rubber will shorten when temperature
exceeds 100°C.
Requirements of the oil seal on the assembly shaft:
1. The surface roughness of the shaft is in accordance with the
provisions of GB1801. The shaft surface in contact with the oil
seal should be ground to a surface roughness Ra0.2 ～ 0.63um and
Rmax = 0.8 ~ 2.5um.
2. The diameter tolerance of the shaft shall not exceed h11
according to GB1801.
3. The chamfer width is according to GB13871-92.
4. Surface hardness: The material of the shaft is preferably carbon
steel and alloy steel. The recommended hardness is HRC45 or higher.
When the medium is dirty and has contaminated impurities from the
outside or the linear speed of the shaft is ≥12m / s, the surface
hardness of the
shaft It should be HRC50 ～ 60, and the depth of quenching layer
should be ≥0.3mm.
5. The shaft is chamfered at 30 degrees (maximum). There should be
no burrs, sharp corners, and spiral processing marks on the
chamfer. The roughness of the chamfered surface Ra ≦ 3.2um. The
heat-treated carbonized layer must be polished and removed.
