Rotary Shaft Seal 85x105x13 FPM/FKM A/SC GRN Single Lip Oil Seal

GRN 85x105x13 FPM/FKM A/SC Single Lip Oil Seal

GRN 85x105x13 FPM/FKM A/SC is a single lip radial shaft oil seal manufactured from fluoroelastomer.

Brand: GRN

Reference: 85X105X13 A FPM

Product type: Radial shaft oil seal

Design: A/SC

Seal type: Single lip

Dimensions: 85x105x13 mm

Inside diameter d: 85 mm

Outside diameter D: 105 mm

Width B: 13 mm

Material: FPM/FKM - Fluoroelastomer

Primary sealing lip: Spring-loaded

Additional dust lip: No

Sales unit: 1 piece

The complete technical identification combines the 85x105x13 mm dimensions, FPM/FKM material and A/SC single lip construction.

GRN 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 housing bore and 13 mm to the seal width.

All three dimensions should be verified when selecting a replacement.

Matching the shaft diameter alone does not establish complete technical interchangeability.

A/SC Single Lip Oil Seal Design

The sealing configuration is:

Design: A/SC

Seal configuration: Single lip

Primary sealing lip: Spring-loaded

Additional dust lip: No

The A/SC construction uses a primary spring-loaded sealing lip to form the main sealing interface against the rotating shaft.

Unlike an AO/TC double lip oil seal, this version does not incorporate an additional dust lip.

The sealing profile should therefore be considered together with dimensions and material when comparing possible replacements.

Spring-Loaded Primary Sealing Lip

The primary sealing lip incorporates a spring.

Primary sealing lip: Spring-loaded

Nominal shaft diameter: 85 mm

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

This construction is characteristic of a conventional radial shaft oil seal and is an important parameter when selecting a corresponding replacement.

Single Lip Oil Seal Without Additional Dust Lip

Seal type: Single lip

Primary sealing lip: Yes

Additional dust lip: No

This distinction is important when comparing the product with double lip 85x105x13 oil seals.

Identical dimensions do not mean that a single lip A/SC seal and a double lip AO/TC seal are structurally identical.

FPM/FKM Fluoroelastomer

The sealing material is:

Material: FPM/FKM - Fluoroelastomer

FPM and FKM are technical designations used for the fluoroelastomer material family under different nomenclature systems.

Fluoroelastomers are used in sealing technology where their specific material properties are required for the operating medium and conditions.

Exact compatibility should always be verified for the specific medium, additives, temperature and actual operating conditions.

FPM/FKM vs Viton Oil Seal

The technical material designation for this product is:

Material: FPM/FKM - Fluoroelastomer

FPM/FKM seals are also frequently searched for as Viton oil seals.

However, Viton® is a trademark for specific fluoroelastomer materials. The FPM/FKM designation alone does not establish that a particular seal is manufactured from genuine Viton® branded compound.

For technical identification, FPM/FKM is therefore the appropriate material designation unless the exact compound manufacturer is confirmed.

85x105x13 FPM Oil Seal

The complete product identification is:

Dimensions: 85x105x13 mm

Material: FPM/FKM

Design: A/SC

Seal type: Single lip

Primary sealing lip: Spring-loaded

Additional dust lip: No

Using the complete specification 85x105x13 FPM/FKM A/SC provides more precise product identification than searching only for an 85x105x13 oil seal.

85x105x13 FKM Rotary Shaft Seal

The terms FPM and FKM refer to the fluoroelastomer material family under different technical nomenclature systems.

For this product:

Shaft diameter: 85 mm

Housing diameter: 105 mm

Width: 13 mm

Material: FPM/FKM

Design: A/SC

Seal configuration: Single lip

This allows the product to be identified naturally as both an 85x105x13 FPM oil seal and an 85x105x13 FKM oil seal.

85x105x13 A/SC vs AO/TC Oil Seal

The sealing configurations are different.

A/SC: Single lip

A/SC additional dust lip: No

AO/TC: Double lip

AO/TC additional dust lip: Yes

The A/SC version uses the spring-loaded primary sealing lip without the additional dust lip found in the AO/TC configuration.

Therefore, an 85x105x13 AO/TC double lip oil seal should not automatically be considered structurally identical to this 85x105x13 A/SC single lip seal.

85x105x13 FPM/FKM vs NBR Oil Seal

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

This product: FPM/FKM

Alternative material: NBR

Dimensions: 85x105x13 mm

FPM/FKM and NBR belong to different elastomer families.

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

How to Select an 85x105x13 Oil Seal

When selecting a corresponding radial shaft seal, verify:

• shaft diameter 85 mm
• outside diameter 105 mm
• width 13 mm
• material FPM/FKM
• design A/SC
• single lip construction
• spring-loaded primary sealing lip
• absence of an additional dust lip
• operating medium
• actual operating conditions
• shaft and housing condition

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

What material is the seal made from?

Material: FPM/FKM - Fluoroelastomer

Are FPM and FKM the same material family?

Yes. FPM and FKM are designations used for the fluoroelastomer material family under different nomenclature systems.

Not automatically. Although the dimensions may be identical, the sealing lip configurations are different.

Can an NBR 85x105x13 oil seal replace the FPM/FKM version?

Not automatically. NBR and FPM/FKM are different elastomer materials, so material compatibility must be verified for the specific application.
