FULL DESCRIPTION

GRN 85x105x13 NBR AO/TC Double Lip Oil Seal

GRN 85x105x13 NBR AO/TC is a double lip radial shaft oil seal manufactured from Nitrile Butadiene Rubber.

Brand: GRN

Product type: Radial shaft oil seal

Dimensions: 85x105x13 mm

Inside diameter d: 85 mm

Outside diameter D: 105 mm

Width B: 13 mm

Material: NBR - Nitrile Butadiene Rubber

Design: AO/TC

Profile: BASL

Seal type: Double lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

Sales unit: 1 piece

The complete technical identification combines the 85x105x13 mm dimensions, NBR material and AO/TC double lip construction.

85x105x13 Oil Seal Dimensions

The principal dimensions are:

Inside diameter d: 85 mm

Outside diameter D: 105 mm

Width B: 13 mm

Complete dimensions: 85x105x13 mm

The 85 mm dimension corresponds to the nominal shaft diameter, 105 mm to the outside diameter of the seal and 13 mm to its width.

All three dimensions should be verified when selecting a replacement.

Matching the 85 mm shaft diameter alone does not establish technical interchangeability.

AO/TC Double Lip Oil Seal Design

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 dust lip.

The primary lip forms the main sealing interface against the rotating shaft, while the additional lip provides an extra barrier on the external side of the principal sealing area.

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

BASL Oil Seal Profile

Profile: BASL

Seal configuration: Double lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

BASL identifies a radial shaft sealing configuration incorporating a primary sealing lip and an additional protective lip.

Depending on the manufacturer and nomenclature system, similar double lip radial shaft seal constructions can be identified using terms such as AO, TC or BASL.

These designations should not, however, be treated as universally interchangeable without checking the exact seal construction.

Spring-Loaded Primary Sealing Lip

Primary sealing lip: Spring-loaded

Nominal shaft diameter: 85 mm

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

The spring-loaded primary lip performs the principal sealing function of the radial shaft seal.

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 and helps restrict external contaminants from reaching the main sealing interface.

This additional lip distinguishes the AO/TC double lip configuration from a corresponding single lip A/SC oil seal.

NBR Nitrile Butadiene Rubber

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

85x105x13 NBR Oil Seal

Complete identification:

Dimensions: 85x105x13 mm

Material: NBR

Design: AO/TC

Profile: BASL

Seal type: Double lip

Primary sealing lip: Spring-loaded

Additional dust lip: Yes

Using the complete specification 85x105x13 NBR AO/TC provides more precise technical identification than searching only for an 85x105x13 oil seal.

85x105x13 Double Lip Rotary Shaft Seal

Shaft diameter: 85 mm

Outside diameter: 105 mm

Width: 13 mm

Material: NBR

Seal configuration: Double lip

The primary sealing lip and additional dust lip form the two-lip configuration of this radial shaft seal.

The complete construction should be considered when comparing alternative 85x105x13 rotary shaft seals.

85x105x13 AO/TC vs A/SC Oil Seal

The two versions differ in sealing lip configuration.

AO/TC: Double lip

AO/TC additional dust lip: Yes

A/SC: Single lip

A/SC additional dust lip: No

The 85x105x13 AO/TC version should therefore not automatically be considered structurally identical to an 85x105x13 A/SC oil seal.

The nominal dimensions may be identical, but the sealing configurations are different.

85x105x13 NBR vs FPM/FKM Oil Seal

This product: NBR

Alternative material: FPM/FKM

Dimensions: 85x105x13 mm

NBR and FPM/FKM are different elastomer families.

An 85x105x13 FPM/FKM oil seal should therefore not automatically be considered materially equivalent to this NBR version solely because the nominal dimensions are identical.

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

How to Select an 85x105x13 NBR Oil Seal

When selecting a corresponding radial shaft seal, verify:

• shaft diameter 85 mm
• outside diameter 105 mm
• width 13 mm
• material NBR
• design AO/TC
• double lip configuration
• spring-loaded primary sealing lip
• additional dust lip
• operating medium
• actual operating conditions
• shaft and housing condition

Matching the 85x105x13 mm dimensions alone does not establish complete technical interchangeability.

FAQ

What are the dimensions of the GRN 85x105x13 oil seal?

Inside diameter d: 85 mm

Outside diameter D: 105 mm

Width B: 13 mm

Complete dimensions: 85x105x13 mm

What does 85x105x13 mean?

The dimensions identify a seal with a nominal 85 mm shaft diameter, 105 mm outside diameter and 13 mm width.

Is the GRN 85x105x13 NBR oil seal double lip?

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

What does BASL mean for this oil seal?

BASL identifies a radial shaft sealing profile with a primary sealing lip and an additional protective lip.

Does the primary sealing lip have a spring?

Yes. The primary sealing lip is spring-loaded.

Does the 85x105x13 AO/TC oil seal have a dust lip?

Yes. It incorporates an additional dust lip.

What material is the oil seal made from?

Material: NBR - Nitrile Butadiene Rubber

What is the difference between AO/TC and A/SC?

AO/TC is a double lip configuration with an additional dust lip. A/SC is a single lip configuration without the additional dust lip.

Is 85x105x13 NBR the same as 85x105x13 FPM/FKM?

No. The dimensions may be identical, but NBR and FPM/FKM are different elastomer materials.

Can any 85x105x13 oil seal replace this product?

Not necessarily. The dimensions, NBR material, double lip construction and sealing profile should all be considered when selecting a replacement.

Is the GRN 85x105x13 oil seal sold individually?

Yes. The sales unit is 1 piece.

How do I select a replacement for the GRN 85x105x13 NBR AO/TC oil seal?

Verify the 85x105x13 mm dimensions, NBR material, AO/TC double lip construction, spring-loaded primary sealing lip, additional dust lip and requirements of the specific application.
