Description
This rotary shaft seal has an internal diameter of 55 mm, an external diameter of 75 mm and a 12 mm width. It is used to seal rotating machine components.
This seal consists of an NBR ring with a reinforcement plate and a worm spring made of spring steel. The external rubber-elastic jacket provides stable sealing and tight fit. Suitable for a shaft circumferential speed of up to 14 m/s.
Changing the seal frequently prevents damage to the housing hole. The seal must be assembled according to DIN 3760 to function optimally.
Pros:
- Suitable for temperatures from -30 to 100°C (-22 to 212°F)
- There is no frictional corrosion thanks to the rubber-elastic jacket
