The NBR Oil Seal 28x47x5 TC is a compact double-lip radial shaft seal designed for a 28 mm shaft, 47 mm housing bore, and 5 mm installation width.
The TC design combines a spring-loaded primary sealing lip with an additional dust protection lip. The primary lip provides dynamic sealing against the rotating shaft, while the auxiliary lip helps protect the main sealing area against dust, dirt and other external contaminants.
The compact 5 mm width makes this seal particularly relevant for assemblies with limited axial installation space.

The TC profile is a double-lip radial shaft seal configuration.
The primary sealing lip operates against the rotating shaft and is supported by a garter spring to maintain sealing contact.
The auxiliary dust lip provides an additional barrier between the primary sealing area and external contamination.
Compared with a single-lip SC seal, the TC configuration provides additional protection against contaminants entering from the outside.
One of the distinguishing features of the 28x47x5 TC oil seal is its compact axial width.
At only 5 mm wide, the seal can be used in appropriately designed assemblies where installation space is restricted but a double-lip sealing configuration is required.
When selecting a replacement, all three dimensions should be verified. A 28x47 mm seal with a different width should not automatically be considered interchangeable.
NBR (Nitrile Butadiene Rubber) is widely used for radial shaft seals due to its good resistance to many mineral oils, lubricating greases and compatible technical fluids.
It is commonly used in general industrial machinery, drive systems and rotating mechanical equipment.
Actual suitability depends on the operating medium, temperature, shaft speed and application conditions.

What are the dimensions of the NBR 28x47x5 TC oil seal?
The seal has a 28 mm shaft diameter, 47 mm housing bore diameter and 5 mm width.
What does TC mean?
TC identifies a double-lip radial shaft seal with a primary spring-loaded sealing lip and an additional dust protection lip.
Does the 28x47x5 TC have a dust lip?
Yes. The auxiliary lip helps protect the primary sealing area against external contamination.
Does the primary sealing lip have a spring?
Yes. The main sealing lip is supported by a garter spring.
Why is the 5 mm width important?
The compact 5 mm width allows installation in appropriately designed assemblies with limited axial space. The correct width should always be verified when selecting a replacement.
What material is the seal made from?
It is manufactured from NBR - Nitrile Butadiene Rubber.
What is the difference between TC and SC?
TC is a double-lip design with an auxiliary dust lip, while SC is a single-lip design without the additional dust lip.
