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.
