1. The type of imported skeleton oil seal
Seal structure analysis of commonly used materials are: schematic diagram of oil seal material Dengqen rubber, fluorine rubber, silicone rubber, polyurethane, PTFE etc.. When selecting oil seal materials, we must consider the compatibility of materials to the working hostages, the adaptability to the working temperature range and the ability of the lip to follow the rotating shaft when rotating at high speed. In general, the temperature of the lip edge of the oil seal is higher than that of the working hostage temperature 20~50. It should be paid attention to when choosing the oil seal material.
For details, please refer to the types and characteristics of rubber.
The working range of the oil seal is related to the materials used in the oil seal: the material is NBR, the -40~120 degree, the Alec rubber (ACM) -30~180 degree, the fluorine rubber (FKM.FPM) -25 -- 300 degrees.
Two. The use of the imported skeleton oil seal:
Engine: crankshaft crankshaft front, rear oil seal valve valve seal (engine repair kit O type) (distributor oil seal, pump oil seal, balance shaft oil seal, oil pump oil seal). Camshaft camshaft oil seal;
Transducer: change = changes is before, after the seal shift rod seal (change device repair kit O (ring) - actuator actuator, seal); rear axle half shaft - half shaft seal differential - (former) after the front wheel rear oil seal oil seal oil seal angle in sagittal direction of machine oil seal (the direction of management package O ring seal (the first half) steering shaft seal).
Characteristics and performance requirements of oil seal products:
1. good wear resistance, strong tearing resistance, good bending strength;
2. tensile strength and fracture elongation rate are large.
3. moderate temperature tolerance (-30~+260 degree)
4. hardness adjustable range (Shaw 80A-95A);
5. the compression permanent deformation rate is low;
6. corrosion resistance, good performance of water resistant solvent, high mechanical strength and service life.
7. resistance to ozone and aging resistance;
8. non-toxic, meet the requirements of environmental protection.
9. the price is low, the quality is guaranteed.
The national standard size has a large number of spot, non-standard size, straight through the large skeleton oil seal ring which is bigger than 1 meters, the rubber special-shaped parts can be customized, the special products are processed in the pattern, and customers are welcome to consult and order the bone seal.
Various types of skeleton oil seal:
