FAQ

What does the TC designation mean?

TC indicates a double lip oil seal with a primary sealing lip and an additional dust lip for improved contamination protection.

Is this seal suitable for gearboxes?

Yes. The TC design is commonly used in industrial and automotive gearboxes where lubricant retention is critical.

Can this oil seal be used in electric motors?

Yes. Rotary shaft seals are frequently installed in electric motors to protect bearings and retain lubrication.

What lubricant types are compatible with NBR?

NBR is compatible with most mineral oils, greases and many standard hydraulic fluids.

Why is a double lip seal preferred?

The secondary lip helps keep dirt, dust and moisture away from the sealing area, increasing equipment reliability.
