Design and Advantages - NBR Double Lip Oil Seal

Manufactured from NBR (nitrile butadiene rubber), this rotary shaft seal offers:

• excellent resistance to oils and grease,

• stable sealing performance under standard automotive operating temperatures,

• good wear resistance and material durability.

The double lip (TBW) construction combines an oil-retaining sealing lip with an external dust lip, significantly extending service life by preventing contamination of the sealing zone. This makes the seal suitable for industrial applications, automotive powertrains, and machinery operating in dusty or variable conditions.
