FAQ

What is the difference between a single-lip and a double-lip shaft seal?

A single-lip shaft seal has one primary sealing lip that retains lubricant, while a double-lip seal includes an additional dust lip for improved protection against dirt, moisture and external contaminants. Double-lip designs are generally preferred for harsher operating environments.

Why is NBR commonly used for rotary shaft seals?

NBR (Nitrile Butadiene Rubber) offers excellent resistance to mineral oils, greases, fuels and mechanical wear while maintaining reliable sealing performance over a wide range of normal operating temperatures. It is one of the most widely used elastomers for automotive and industrial shaft seals.

How do I select the correct rotary shaft seal?

The correct seal should match the shaft diameter (inner diameter), housing bore (outer diameter) and seal width. Operating conditions such as lubrication type, temperature, shaft speed, pressure and environmental contamination should also be considered when selecting the appropriate sealing design.

Is CORTECO 19015047B suitable for contaminated environments?

Yes. The durable NBR material and robust TA2 / B2SL construction provide reliable performance in many industrial and automotive applications. For extremely dusty or highly contaminated environments, a seal with an additional dust lip may provide enhanced protection.
