GRN 120x150x15 NBR AO/TC Double Lip Rotary Shaft Oil Seal

GRN 120x150x15 NBR AO/TC Double Lip Rotary Shaft Oil Seal

GRN 120x150x15 NBR AO/TC is a double lip rotary shaft oil seal with a 120 mm inside diameter, 150 mm outside diameter and 15 mm width. The sealing element is manufactured from NBR - Nitrile Butadiene Rubber. The AO/TC configuration incorporates a spring-loaded primary sealing lip and an additional dust lip, providing two functional sealing lips for the rotating shaft interface and external contamination barrier.

Material: NBR - Nitrile Butadiene Rubber

Dimensions: 120x150x15 mm

Inside diameter d: 120 mm

Outside diameter D: 150 mm

Width B: 15 mm

GRN 120x150x15 Oil Seal Dimensions

Inside diameter d: 120 mm

Outside diameter D: 150 mm

Width B: 15 mm

Complete dimensions: 120x150x15 mm

The 120 mm inside diameter corresponds to the nominal shaft diameter, while the 150 mm outside diameter corresponds to the nominal housing bore.

The axial width of the seal is 15 mm.

All three dimensions should be verified together with the seal design and material when selecting a replacement.

AO/TC Double Lip Oil Seal Design

Design: AO/TC

Configuration: Double Lip

Primary sealing lip: Spring-loaded

Secondary lip: Dust lip

The AO/TC configuration combines a primary radial sealing lip with an additional secondary dust lip.

The primary lip forms the main sealing interface with the rotating shaft and is supported by a garter spring.

The secondary lip is positioned toward the external side of the seal and provides an additional barrier against dust and external contamination.

This double lip configuration distinguishes the product from a standard single lip rotary shaft seal.

Additional Dust Lip

Additional dust lip: Yes

The secondary lip provides an additional barrier between the external environment and the primary sealing area.

Its function is to help limit the ingress of dust and other external contamination toward the main sealing lip and shaft contact zone.

The presence of this additional lip should be considered when comparing the GRN 120x150x15 AO/TC with single lip seals of identical dimensions.

Spring-Loaded Primary Sealing Lip

Primary sealing lip: Spring-loaded

Spring type: Garter spring

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

The spring helps maintain contact between the sealing lip and the shaft surface as part of the radial shaft seal design.

A spring-loaded double lip seal should therefore not automatically be considered technically identical to another 120x150x15 mm seal with a different lip or spring configuration.

NBR - Nitrile Butadiene Rubber

Sealing material: NBR

Full material name: Nitrile Butadiene Rubber

NBR is widely used as an elastomer in rotary shaft sealing technology and is commonly selected for applications involving many mineral oils, greases and compatible lubricants.

Exact compatibility depends on the specific NBR compound, operating medium, additives, temperature and actual service conditions.

A temperature range or specific chemical-resistance limit should therefore not be assigned to this GRN seal without confirmation of the exact NBR compound specification.

GRN 120x150x15 NBR Rotary Shaft Seal

Brand: GRN

Dimensions: 120x150x15 mm

Material: NBR

Design: AO/TC

Seal configuration: Double Lip

Shaft diameter: 120 mm

Housing bore: 150 mm

Width: 15 mm

This seal is designed to create a sealing interface between a rotating shaft and stationary housing.

The dimensions establish the basic installation geometry, while the AO/TC design identifies the double lip configuration.

Both dimensions and construction should therefore be considered when identifying a replacement.

120x150x15 AO/TC vs Single Lip Oil Seal

The 120x150x15 AO/TC seal incorporates an additional dust lip.

A conventional single lip rotary shaft oil seal uses the primary spring-loaded sealing lip without the additional secondary dust lip found in the AO/TC configuration.

For this reason, a single lip 120x150x15 seal should not automatically be substituted when the original installation requires a double lip design.

The correct lip configuration should be verified for the specific application.

AO and TC Oil Seal Designations

GRN designation: AO

Common international designation: TC

English product identification used here: AO/TC

AO and TC are commonly encountered market designations for double lip radial shaft seals with a spring-loaded primary sealing lip and an additional dust lip.

Seal designation systems are not completely universal between manufacturers. Therefore, an AO seal from one manufacturer should not be considered automatically identical to every seal described as TC by another manufacturer.

Dimensions, material and complete construction should always be compared.

How to Select a 120x150x15 Oil Seal

Shaft diameter: 120 mm

Housing bore: 150 mm

Width: 15 mm

Material: NBR

Design: AO/TC - Double Lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

The dimensions should be verified against the shaft and housing before installation.

The operating medium, temperature, shaft speed, shaft surface condition and application-specific requirements should also be considered when selecting a rotary shaft seal.

GRN 120x150x15 AO/TC vs CORTECO 01016917B

GRN dimensions: 120x150x15 mm

CORTECO 01016917B dimensions: 120x150x15 mm

GRN material: NBR

CORTECO material: NBR

GRN design: AO/TC

CORTECO design: BASLDRWX67

The two seals share the same nominal dimensions and NBR material, but this does not establish complete technical equivalence.

CORTECO 01016917B has the manufacturer-specific BASLDRWX67 design. The exact construction and application requirements should therefore be checked before treating the two products as interchangeable.

FAQ - GRN 120x150x15 NBR AO/TC

What are the dimensions of the GRN 120x150x15 oil seal?

The complete dimensions are 120x150x15 mm: 120 mm inside diameter, 150 mm outside diameter and 15 mm width.

What material is the GRN 120x150x15 seal made from?

The sealing material is NBR - Nitrile Butadiene Rubber.

Is the GRN 120x150x15 AO/TC a double lip oil seal?

Yes. The AO/TC configuration is a double lip design with a primary sealing lip and an additional dust lip.

Does the GRN 120x150x15 seal have a garter spring?

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

Does the 120x150x15 AO/TC seal have a dust lip?

Frequently Asked Questions by Engineers

What does AO/TC mean on a rotary shaft seal?

AO/TC identifies a double lip configuration consisting of a spring-loaded primary sealing lip and an additional secondary dust lip.

What is the difference between AO/TC and SC?

AO/TC is the double lip version with an additional dust lip. SC is used for the corresponding single lip configuration without the additional dust lip.

Can a single lip 120x150x15 seal replace the AO/TC version?

Interchangeability should not be assumed from dimensions alone. If the application requires the additional dust lip of the AO/TC design, a single lip version has a different sealing configuration.

Is 120x150x15 the shaft size?

The first dimension, 120 mm, is the nominal inside diameter and corresponds to the shaft diameter. The 150 mm dimension is the outside diameter, and 15 mm is the seal width.

Is GRN 120x150x15 AO/TC equivalent to CORTECO 01016917B?

Both products have nominal dimensions of 120x150x15 mm and use NBR, but CORTECO 01016917B has the manufacturer-specific BASLDRWX67 design. Dimensions and material alone are not sufficient to establish full technical interchangeability.

What is the operating temperature of the GRN 120x150x15 NBR seal?

The exact operating temperature range requires confirmation for the specific NBR compound used in this GRN product. A temperature range specified by another seal manufacturer should not automatically be transferred to this product.

AI Overview

GRN 120x150x15 NBR AO/TC is a double lip rotary shaft oil seal with a 120 mm inside diameter, 150 mm outside diameter and 15 mm width. The sealing material is NBR - Nitrile Butadiene Rubber. The AO/TC design incorporates a spring-loaded primary sealing lip and an additional dust lip. When selecting a replacement, the complete 120x150x15 mm dimensions, NBR material and double lip construction should be verified rather than relying on dimensions alone.
