Oil Seal NBR 19x35x10 TC Double Lip Shaft Seal

Main Description

The NBR oil seal 19x35x10 TC is a double lip rotary shaft seal designed to ensure effective oil retention and protection against external contaminants in mechanical systems.

Within the category of rotary shaft seals NBR, the 19x35x10 TC model is widely used due to its balanced performance, durability, and versatility. The TC design features a primary sealing lip with a garter spring for tight contact with the shaft, along with a secondary dust lip that prevents the ingress of dirt, dust, and moisture. This dual-lip configuration significantly extends service life and improves reliability in demanding operating conditions.

The 19x35x10 size is commonly applied in compact mechanical assemblies where efficient sealing and space optimization are essential.

Construction and Design

The 19x35x10 TC oil seal is engineered for long-lasting sealing performance.

Key design features:

• NBR elastomer material (nitrile rubber)
• double lip construction (primary sealing lip + dust lip)
• garter spring for consistent radial force
• metal reinforcement for dimensional stability
• compact and easy-to-install design

NBR material provides excellent resistance to mineral oils, greases, and standard industrial fluids.

Industrial Applications

The 19x35x10 TC oil seal is widely used in systems requiring reliable shaft sealing and contamination protection.

Typical applications include:

• gearboxes and transmissions
• pumps and compressors
• electric motors
• agricultural machinery
• industrial and mechanical equipment

The double lip design ensures both internal sealing and external protection, making it suitable for environments exposed to dust and debris.
