Imported NAK NOK framework oil seal rotating shaft lip seal tc45*78*12
Framework oil seal is a mechanical component for sealing, also known as rotary shaft lip seal ring
The friction part of the machine has oil entering during the operation of the machine
In order to prevent the oil from leaking from the gap of the machine, an oil seal is used
With the development of mechanical technology, in addition to oil, it is also necessary to prevent the leakage of water and chemical solution and the invasion of dust, soil and sand from the outside
At this time, oil seals should also be used

The oil seal usually has four parts:
1
lip end: it is in the shape of an inclined wedge, which acts as a sealing fluid according to the pressure shaft surface at the end

2
sealing lip: the sealing lip is a flexible elastomer, which is designed to maintain a stable sealing effect under the influence of mechanical vibration and pressure change of sealing fluid, and to maintain a stable contact state between the lip and the shaft surface
In addition, the spring can increase the pressing force of the sealing lip to the shaft and maintain the pressing force

3
dust lip: the dust lip is the auxiliary lip that does not contact with the spring
It plays a role in preventing dust intrusion

4
fitting part: the fitting part is used to prevent fluid leakage and invasion from the contact surface between the outer peripheral surface of the oil seal and the inner surface of the cavity while the oil seal is fixed in the cavity hole
In addition, the metal framework plays a protective role when the oil seal is fixed in the cavity
