Rotary Shaft Seal 38x57x7 NBR TC Oil Seal Double Lip

The Rotary Shaft Seal 38x57x7 NBR Double‑Lip TC Oil Seal is engineered for high-demand automotive and industrial applications. Crafted from tough Nitrile Butadiene Rubber (NBR), it delivers outstanding resistance against oil, wear, and elevated temperatures. The TC double-lip design includes a spring-loaded primary sealing lip and a secondary lip for optimal dust and contaminant defense.

Key Features:

• Dimensions: 38 mm inner diameter x 57 mm outer diameter x 7 mm width—standard precision sizing for compatibility with common shaft assemblies.

• Material (NBR): Excellent oil resistance and mechanical durability, offering reliable performance in rotating machinery environments.

• TC Double‑Lip Construction: Delivers a superior seal by combining a spring‑supported primary lip with a dust‑exclusion secondary lip—boosting lubrication retention, reducing leakage, and extending service life.

• Robust Durability: Suitable for shafts in engines, gearboxes, pumps, and industrial assemblies under strenuous conditions.

This seal effectively prevents lubricant loss and excludes debris, ensuring smooth mechanical operations and minimizing maintenance costs.
