Overview
The NBR Oil Seal 28x42x8 TC GRN is a double-lip radial shaft seal designed for a 28 mm shaft, 42 mm housing bore, and 8 mm installation width.
The TC design combines a spring-loaded primary sealing lip with an additional dust lip. The primary lip provides dynamic sealing against the rotating shaft, while the secondary lip helps protect the sealing area against dust, dirt and other external contaminants. This double-lip configuration is characteristic of TC radial shaft seals.

TC Double Lip Design
The TC profile is a widely used double-lip radial shaft seal configuration. It incorporates a spring-loaded primary lip for retaining lubricant and a secondary lip for additional protection against external contamination. TC seals typically feature a rubber-covered outside diameter.
Compared with a basic single-lip seal, the additional dust lip provides greater protection for the primary sealing area.
NBR Material
NBR (Nitrile Butadiene Rubber) is widely used for industrial radial shaft seals because of its good resistance to many mineral oils and lubricating greases.
NBR is commonly selected for gearboxes, pumps, motors and other mechanical systems. Final material selection should consider the operating medium, temperature, shaft speed and application conditions.
