NBR 146x163x7 TC Double Lip Rotary Shaft Seal

Construction and design

NBR 146x163x7 TC is a compact rotary shaft seal designed for industrial applications requiring efficient oil retention and protection against external contamination.

The TC design represents a double lip sealing configuration with a primary sealing lip supported by a garter spring and an additional dust lip. This ensures effective sealing performance in dynamic applications while preventing the ingress of dirt, dust and moisture.

The seal is manufactured from NBR elastomer, providing reliable resistance to oils, greases and typical industrial fluids. Its slim 7 mm width allows installation in applications with limited mounting space.
