Oil seals and other seals there are those strengths?
An oil seal structure is simple, easily manufactured. Simple oil seal once can be molded even the most complex oil seal, the manufacturing process is not complicated. Metal skeleton oil seal only through stamping, adhesive bonding, mosaic, molding and other processes can be of metal and rubber to the requirements of the oil seal.
2, oil seal, light weight, supplies. Each of oil seals are thin-walled metal parts and rubber parts combination, the material cost little, and thus the weight of each oil seal is very light.
3, the oil seal installation location, small size, axial, and easily processed and compact machine.
4, the sealing function of oil seal, and longer life. Eccentricity on the vibration of the machine spindle has a certain degree of adaptability.
5, oil seal disassembly is easy, to facilitate inspection.
6 cheap oil seal.
The oil seals the disadvantage is that can not withstand high pressure, we can only make the sealing of the bearing lubricant.
Oil seal of the scope of work as follows:
A working pressure of the oil seal ~ 0.3MPa
2, the oil seal sealing surface linear velocity of low-speed type <4m / s, high speed 4 ~ 15m / s
3, the oil seal operating temperature -60 to 150 ° C (with rubber types)
4, oil seal combined medium oil, water and weak erosion of liquid
5, seal life 500 ~ 2000h
