Rotary Shaft Seal 60x70x8 NBR AO/TC GRN Double Lip Oil Seal

GRN 60x70x8 NBR AO/TC Double Lip Oil Seal

GRN 60x70x8 NBR AO/TC is a double lip radial shaft oil seal manufactured from Nitrile Butadiene Rubber.

Brand: GRN

Reference: 60X70X8

Product type: Radial shaft oil seal

Design: AO/TC

Seal type: Double lip

Dimensions: 60x70x8 mm

Inside diameter d: 60 mm

Outside diameter D: 70 mm

Width B: 8 mm

Material: NBR - Nitrile Butadiene Rubber

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

Sales unit: 1 piece

The complete product identification combines the 60x70x8 mm dimensions, NBR material and double lip AO/TC construction.

GRN 60x70x8 Oil Seal Dimensions

The principal dimensions are:

Inside diameter d: 60 mm

Outside diameter D: 70 mm

Width B: 8 mm

Complete dimensions: 60x70x8 mm

The 60 mm inside diameter corresponds to the nominal shaft diameter, the 70 mm outside diameter to the housing bore, and the 8 mm value to the seal width.

All three dimensions should be verified when selecting a corresponding replacement.

Matching the 60 mm shaft diameter alone does not establish technical interchangeability.

AO/TC Double Lip Oil Seal Design

The sealing configuration is:

Design: AO/TC

Seal configuration: Double lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

The AO/TC construction combines the primary sealing lip with an additional lip on the external side of the main sealing interface.

The primary lip performs the principal sealing function against the rotating shaft, while the additional dust lip provides an additional barrier against external contamination.

This lip configuration is an important part of the technical identification of the seal.

Spring-Loaded Primary Sealing Lip

The primary sealing lip incorporates a spring.

Primary sealing lip: Spring-loaded

Nominal shaft diameter: 60 mm

The spring helps maintain contact between the primary sealing edge and the shaft surface.

A replacement should therefore be selected not only according to dimensions but also according to the required sealing lip configuration.

Additional Dust Lip

GRN 60x70x8 AO/TC incorporates an additional dust lip.

Additional dust lip: Yes

Seal configuration: Double lip

The additional lip provides an extra barrier on the external side of the primary sealing area.

This characteristic distinguishes the AO/TC double lip version from a corresponding single lip seal.

NBR Nitrile Butadiene Rubber

The sealing material is:

Material: NBR - Nitrile Butadiene Rubber

NBR is one of the most widely used elastomers in radial shaft sealing technology.

It is commonly used in sealing applications involving many mineral oils, lubricating greases and other compatible technical media.

Exact material compatibility depends on the specific medium, additives, temperature and actual operating conditions.

60x70x8 NBR Oil Seal

The complete dimensional and material identification is:

Dimensions: 60x70x8 mm

Material: NBR

Design: AO/TC

Seal type: Double lip

Additional dust lip: Yes

Searching by the complete specification is more precise than searching only for a 60x70x8 oil seal because seals with identical dimensions can be available in different materials and sealing configurations.

60x70x8 Double Lip Rotary Shaft Seal

GRN 60x70x8 AO/TC is designed as a radial shaft sealing element.

Shaft diameter: 60 mm

Housing diameter: 70 mm

Seal width: 8 mm

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

The double lip configuration should be considered when comparing this product with alternative rotary shaft seals of the same nominal dimensions.

60x70x8 AO/TC vs Single Lip Oil Seal

The principal difference is the sealing lip configuration.

AO/TC version: Double lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

A corresponding single lip oil seal does not have the same two-lip configuration.

A single lip 60x70x8 oil seal should therefore not automatically be considered structurally equivalent to the AO/TC version solely because the dimensions are identical.

60x70x8 NBR vs FKM Oil Seal

Oil seals with identical dimensions can be manufactured from different elastomers.

This product: NBR

Alternative material: FPM/FKM

Dimensions: 60x70x8 mm

NBR and FPM/FKM are different sealing materials and should not automatically be considered materially interchangeable.

Material selection should be based on the operating medium and actual operating conditions.

How to Select a 60x70x8 Oil Seal

When selecting a corresponding radial shaft seal, verify:

• shaft diameter 60 mm
• outside diameter 70 mm
• width 8 mm
• material NBR
• design AO/TC
• double lip construction
• spring-loaded primary sealing lip
• additional dust lip
• operating medium
• actual operating conditions
• shaft and housing condition

Matching the 60x70x8 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of the GRN 60x70x8 oil seal?

Inside diameter d: 60 mm

Outside diameter D: 70 mm

Width B: 8 mm

Complete dimensions: 60x70x8 mm

What does 60x70x8 mean?

The dimensions identify a seal for a nominal 60 mm shaft diameter, 70 mm housing bore and 8 mm seal width.

Is the GRN 60x70x8 AO/TC oil seal double lip?

Yes. The AO/TC construction is double lip, incorporating a primary sealing lip and an additional dust lip.

Does the primary sealing lip have a spring?

Yes. The primary sealing lip is spring-loaded.

Does the 60x70x8 AO/TC oil seal have a dust lip?

Yes. It incorporates an additional dust lip on the external side of the primary sealing area.

What material is the GRN 60x70x8 oil seal made from?

Material: NBR - Nitrile Butadiene Rubber

What is the difference between AO/TC and a single lip oil seal?

The AO/TC version incorporates a spring-loaded primary sealing lip plus an additional dust lip. A single lip version does not have the same two-lip configuration.

Can an FKM 60x70x8 oil seal replace this NBR seal?

Not automatically. Although the dimensions may be identical, NBR and FPM/FKM are different elastomer materials. Material compatibility should be verified for the specific application.

Can any 60x70x8 oil seal replace this product?

Not necessarily. Matching dimensions alone do not confirm complete interchangeability. The NBR material, AO/TC design and double lip configuration should also be considered.

Is the GRN 60x70x8 oil seal sold individually?

Yes. The sales unit is 1 piece.

How do I select a replacement for GRN 60x70x8 NBR AO/TC?

Verify the 60x70x8 mm dimensions, NBR material, AO/TC double lip construction, primary spring-loaded sealing lip, additional dust lip and requirements of the specific application.
