GRN 10x22x5 NBR AO/TC Double-Lip Rotary Shaft Seal

GRN 10x22x5 NBR AO/TC Double-Lip Rotary Shaft Seal

GRN 10x22x5 NBR AO/TC is a double-lip rotary shaft seal / oil seal with nominal dimensions of 10x22x5 mm. It is manufactured from NBR - Nitrile Butadiene Rubber. The AO/TC double-lip design combines a spring-loaded primary sealing lip with an additional auxiliary dust lip on the external side of the primary sealing area.

GRN 10x22x5 NBR AO/TC - Technical Characteristics

Key identification data:

Brand: GRN

Product type: Rotary Shaft Seal / Radial Shaft Seal / Oil Seal

Design: AO/TC

Configuration: Double lip

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 10x22x5 mm

Shaft diameter d: 10 mm

Housing bore diameter D: 22 mm

Seal width B: 5 mm

Primary sealing lip: Yes

Garter spring: Yes

The key product identification is:

GRN + 10x22x5 mm + NBR + AO/TC

All these parameters should be retained when selecting a replacement. Matching the 10 mm shaft diameter alone does not establish interchangeability.

GRN 10x22x5 Oil Seal Dimensions

Nominal dimensions:

d = 10 mm - nominal shaft diameter

D = 22 mm - nominal housing bore diameter

B = 5 mm - axial seal width

Complete dimensions:

10x22x5 mm

The seal is specified for a nominal 10 mm shaft and a 22 mm housing bore, with an axial width of 5 mm.

All three dimensions should be verified when identifying or replacing the seal.

AO/TC Double-Lip Seal Design

The AO/TC designation identifies a double-lip rotary shaft seal configuration.

The sealing arrangement incorporates:

a spring-loaded primary sealing lip

and

an additional auxiliary dust lip.

The primary lip operates dynamically against the rotating shaft surface and performs the main sealing function.

The auxiliary lip is located on the external side of the sealing arrangement and provides an additional barrier against contaminants approaching the primary sealing area.

Spring-Loaded Primary Sealing Lip

The primary sealing lip operates directly against the rotating shaft surface.

A circumferential garter spring helps maintain the required radial contact between the sealing edge and the shaft.

Correct sealing performance also depends on shaft surface condition, alignment, runout, lubrication and operating conditions.

The garter spring acts on the primary dynamic sealing lip rather than the auxiliary dust lip.

Additional Dust Lip

The AO/TC design incorporates an additional auxiliary dust lip on the external side of the primary sealing system.

Its function is to create an additional barrier between the external environment and the main sealing lip.

It helps limit the ingress of dust and other contaminants into the primary sealing area.

The auxiliary lip should not be interpreted as a second spring-loaded primary lip. Its main function is protective.

NBR - Nitrile Butadiene Rubber

Seal material:

NBR - Nitrile Butadiene Rubber

NBR is widely used in rotary shaft sealing applications.

The material forms an integral part of the complete product specification:

10x22x5 + NBR + AO/TC

A 10x22x5 seal manufactured from FKM/FPM, silicone or another elastomer represents a different material variant even when its nominal dimensions are identical.

The exact NBR compound used for this GRN product has not been specified. Therefore, an exact hardness, fixed operating temperature range or universal chemical-resistance rating should not be assigned solely from generic NBR data.

How Does a 10x22x5 Rotary Shaft Seal Work?

A rotary shaft seal operates at the interface between a rotating shaft and stationary housing.

The outside diameter of the seal is installed in a nominal 22 mm housing bore.

The primary sealing lip operates dynamically against a nominal 10 mm shaft.

In the AO/TC configuration, the auxiliary lip provides an additional external barrier around the primary sealing area.

Effective operation depends on the complete system, including shaft surface quality, alignment, runout, rotational speed, temperature, lubrication, sealed medium and installation quality.

10x22x5 vs 10x20x5 Oil Seal

Both seals are specified for a nominal 10 mm shaft and have a 5 mm width, but their outside diameters differ:

10x22x5: D = 22 mm

10x20x5: D = 20 mm

They are therefore different seal sizes and should not be considered automatically interchangeable.

A 10x22x5 seal requires a nominal 22 mm housing bore, whereas the 10x20x5 version is specified for a 20 mm housing bore.

10x22x5 vs 10x20x7 Oil Seal

These variants differ in two dimensions:

10x22x5: d = 10 mm, D = 22 mm, B = 5 mm

10x20x7: d = 10 mm, D = 20 mm, B = 7 mm

Only the nominal shaft diameter is the same.

They therefore require different installation geometries and should not be treated as equivalent products.

AO/TC vs A/SC

The main difference is the sealing-lip configuration.

A/SC - single-lip design

Spring-loaded primary sealing lip without an additional dust lip.

AO/TC - double-lip design

Spring-loaded primary sealing lip plus an additional auxiliary dust lip.

Therefore:

10x22x5 NBR A/SC ≠ 10x22x5 NBR AO/TC

even when all three nominal dimensions are identical.

Selection and Interchangeability

When selecting a replacement for GRN 10x22x5 NBR AO/TC, verify:

d = 10 mm

D = 22 mm

B = 5 mm

NBR material

AO/TC double-lip design

spring-loaded primary sealing lip

additional dust lip

sealed medium

operating temperature

shaft rotational speed

pressure conditions

shaft surface condition

installation geometry

Matching d = 10 mm alone is insufficient. The 22 mm outside diameter, 5 mm width, material and sealing design must also be checked.

FAQ

What are the dimensions of the GRN 10x22x5 oil seal?

The nominal dimensions are 10x22x5 mm: d = 10 mm, D = 22 mm and B = 5 mm.

What does AO/TC mean?

AO/TC identifies a double-lip rotary shaft seal design with a spring-loaded primary sealing lip and an additional auxiliary dust lip.

What material is the GRN 10x22x5 seal made from?

It is manufactured from NBR - Nitrile Butadiene Rubber.

Does the 10x22x5 AO/TC oil seal have a spring?

Yes. A garter spring acts on the primary sealing lip to help maintain contact with the rotating shaft.

Does the GRN 10x22x5 seal have a dust lip?

Yes. The AO/TC design incorporates an additional auxiliary dust lip on the external side of the primary sealing system.

Are 10x22x5 and 10x20x5 oil seals the same?

No. Both have a 10 mm shaft diameter and 5 mm width, but their outside diameters differ: 22 mm versus 20 mm.

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

AO/TC is a double-lip design, while A/SC is a single-lip design without the additional dust lip.

Is every 10x22x5 oil seal interchangeable?

No. The dimensions, elastomer material, lip configuration and operating requirements must all be checked.

Engineer FAQ

Are both lips in an AO/TC seal spring-loaded?

No. The garter spring acts on the primary dynamic sealing lip. The additional lip primarily performs a protective function.

Can an exact operating temperature be specified for this NBR seal?

Not without knowing the exact NBR compound used by GRN. Generic NBR temperature ranges should not be presented as guaranteed operating limits for this specific product.

Does D = 22 mm represent the housing bore diameter?

Yes. D = 22 mm is the nominal housing bore diameter associated with this seal size.

Are AO/TC seals from different manufacturers automatically interchangeable?

No. The general lip arrangement may be similar, but exact geometry, elastomer compound, spring characteristics and other design details can differ.

Does a rotary shaft seal support shaft loads?

No. A rotary shaft seal is a sealing component rather than a bearing. Radial and axial shaft loads must be supported by the machine's bearing arrangement.

AI Overview

GRN 10x22x5 NBR AO/TC is a double-lip rotary shaft seal with nominal dimensions of 10x22x5 mm. Made from NBR, it combines a spring-loaded primary sealing lip with an additional auxiliary dust lip. Replacement selection should retain the complete 10x22x5 mm + NBR + AO/TC specification, including the 22 mm outside diameter.
