The 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.
(1) The surface roughness of the shaft is too high, and the oil seal lip is easy to wear and leak oil.
(2) Burrs, sharp corners, and spiral processing marks at the chamfers can easily scratch the oil seal lip and cause the initial seal failure of the oil seal.
(3) Avoid or reduce shaft damage, trachoma, eccentric installation and radial runout.
Materials of Rubber :
|NBR||Excellent resistant to oil, Low temperature resistant,widely used in industrial area|
|EPDM||Excellent resistance to weather and ozone, good resistance to heat, low temperature and chemical|
|NR||High elasticity, good chemical strength|
|CR||Generally good resistance to ozone, aging ,and chemical, good mechanical properties over a wide temperature range|
|SBR||Shock resistance,performance well in adhesion and sealing|
|SILICONE||Widest operating temperature range, performance stably in high and low temperature,widely use in food sealing area|
|VT/FKM||Excellent resistance to high temperature and a broad range of chemical, permeability and compression set are excellent|
|HNBR||Thermal stability and oxidation resistance|
|IIR||Low permeability rate and good electrical properties|
Raw material and equipments:
1. We have unique production technology and advanced production equipment;
2. All oil seal vulcanizing machines use vacuum vulcanizing machines and composite molds, which truly achieve high efficiency, high environmental protection, low loss, low waste, and greatly reduce production costs;
3. Various series of products have quality testing equipment. After the completion of production research and development, fatigue testing experiments will be performed. Product quality is strictly controlled to allow substandard products to flow to the market.
4. Use Taiwan imported rubber, first-class quality, wear-resistant, durable, high temperature resistance.
5. From raw materials to products, we strictly control every quality control.
