GRN 10x30x10 NBR TC Oil Seal - Double Lip Rotary Shaft Seal

Overview

The GRN 10x30x10 NBR TC Oil Seal is a double-lip radial shaft seal with a 10 mm shaft diameter, 30 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 operates directly against the rotating shaft, providing the main dynamic sealing function and helping retain lubricant within the assembly. The additional lip helps protect the primary sealing area against dust, dirt and other external contaminants.

Manufactured from NBR - Nitrile Butadiene Rubber, this GRN oil seal is intended for appropriately selected industrial and mechanical sealing applications.

TC Double-Lip Design

The TC configuration incorporates two functional sealing lips.

The primary sealing lip operates directly against the rotating shaft and is supported by a garter spring. This provides the primary sealing function and helps retain lubricant within the mechanical assembly.

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

Compared with an SC single-lip seal, the TC configuration provides an additional protective lip.

Dimensions of the GRN 10x30x10 Oil Seal

The principal installation dimensions are:

d: 10 mm
D: 30 mm
B: 10 mm

The seal is designed for a 10 mm nominal shaft diameter and a 30 mm housing bore, with an axial width of 10 mm.

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

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. This makes NBR suitable for numerous standard industrial sealing applications.

Final suitability depends on the operating medium, temperature, shaft speed, pressure conditions and actual application requirements.

Industrial Applications

The GRN 10x30x10 NBR TC oil seal can be used in appropriately designed:

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

Operational Advantages

• 10x30x10 mm installation dimensions.
• TC double-lip construction.
• NBR nitrile rubber material.
