NBR Oil Seal 32x47x10 TC - Double Lip Rotary Shaft Seal

Overview

The NBR Oil Seal 32x47x10 TC is a double-lip radial shaft seal with a 32 mm shaft diameter, 47 mm housing bore and 10 mm width.

The TC design combines a spring-loaded primary sealing lip with an auxiliary dust lip. The primary lip provides dynamic sealing against the rotating shaft and helps retain lubricant within the assembly, while the additional lip helps protect the main sealing area against dust, dirt and other external contaminants.

TC Double-Lip Design

The TC profile uses two functional lips.

The primary sealing lip operates directly against the rotating shaft and is supported by a garter spring. This provides the main sealing function and helps prevent lubricant leakage.

The auxiliary dust lip provides an additional barrier between the external environment and the primary sealing area, helping reduce the ingress of contaminants.

Compared with an SC single-lip seal, the TC configuration provides additional external contamination protection.

NBR Material

NBR (Nitrile Butadiene Rubber) is one of the most widely used elastomers for industrial radial shaft seals.

It provides good resistance to many mineral oils, lubricating greases and compatible technical fluids. NBR is therefore commonly used in gearboxes, pumps, motors and general industrial machinery.

Final suitability should be determined according to the operating medium, temperature, shaft speed and actual application conditions.

Dimensions of the 32x47x10 Oil Seal

The principal installation dimensions are:

d: 32 mm
D: 47 mm
B: 10 mm

When selecting a replacement, all three dimensions should be verified together with the TC double-lip configuration and NBR material.

An oil seal with the same 32x47x10 mm dimensions but a different material or lip design should not automatically be considered interchangeable.

Industrial Applications

The NBR 32x47x10 TC oil seal can be used in appropriately designed:

• Gearboxes
• Pumps
• Electric motors
• Drive systems
• Industrial machinery
• Agricultural equipment
• Rotating mechanisms
• Mechanical assemblies

Operational Advantages

• 32x47x10 mm dimensions.
• TC double-lip construction.
• NBR nitrile rubber material.
• Spring-loaded primary sealing lip.
• Auxiliary dust protection lip.
• Suitable for industrial rotating equipment.

FAQ

What are the dimensions of the NBR 32x47x10 TC oil seal?

The seal has a 32 mm shaft diameter, 47 mm housing bore diameter and 10 mm width.

What does TC mean on an oil seal?

TC identifies a double-lip radial shaft seal with a spring-loaded primary sealing lip and an auxiliary dust lip.

Does the 32x47x10 TC oil seal have a dust lip?

Yes. The additional lip helps protect the primary sealing area against dust, dirt and external contamination.

Does the primary sealing lip have a spring?

Yes. The primary sealing lip is supported by a garter spring.

What material is the 32x47x10 seal made from?

The seal 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.

Can any 32x47x10 oil seal be used as a replacement?

Not necessarily. The dimensions, material, lip configuration and operating requirements should all be verified before replacement.
