Rotary Shaft Oil Seal 11x17x4 mm NBR TC Double Lip with Garter Spring

Main Description

The Rotary Shaft Oil Seal 11x17x4 mm NBR TC Double Lip with Garter Spring is a compact radial shaft sealing solution designed for reliable oil retention and protection against contamination in rotating mechanical systems. Manufactured from durable NBR nitrile rubber, this oil seal provides excellent resistance to mineral oils, lubricants, and standard industrial operating conditions.

The TC construction features a double lip sealing design consisting of a primary oil sealing lip and an additional dust protection lip. This configuration improves sealing efficiency and protects internal mechanical components against dust, moisture, and external contaminants. The integrated garter spring maintains constant radial pressure on the shaft surface, ensuring stable sealing performance even during dynamic operation and varying rotational speeds.

The 11x17x4 mm size belongs to the category of compact rotary shaft seals widely used in electric motors, pumps, gearboxes, agricultural equipment, industrial automation systems, and lightweight drivetrain assemblies. TC type oil seals are commonly selected for applications requiring enhanced contamination protection and long operational service life.

NBR material provides a good balance between flexibility, wear resistance, and oil compatibility, making this seal suitable for a broad range of industrial and technical applications.
