NBR Design CS Rotary Shaft Seal 190x220x12mm

This rotary shaft seal has an internal diameter of 190 mm, an external diameter of 220 mm and a 12 mm width. It is used to seal rotating machine components.

This seal consists of an NBR ring with an external reinforcement plate and a worm spring made of spring steel. The plate has a reinforcing cap. Sealing and assembly are the same as design B. Preferably used in harsh operating conditions and for larger dimensions. Suitable for a shaft circumferential speed of up to 14 m/s.

Pros:

• Suitable for temperatures from -30 to 100°C (-22 to 212°F)
• Less sensitive to assembly errors thanks to the reinforcing cap
• Provided with a dust lip for protection from dirt and corrosion
