NBR Design A Rotary Shaft Seal 22x40x7mm [10 Pieces]

This rotary shaft seal has an internal diameter of 22 mm, an external diameter of 40 mm and a 7 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 when exposed to high temperatures and high pressures. 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
