NBR 10x22x6/6.5 AO/TC Double-Lip Rotary Shaft Seal

NBR 10x22x6/6.5 AO/TC Double-Lip Rotary Shaft Seal

NBR 10x22x6/6.5 AO/TC is a double-lip rotary shaft seal / oil seal with a nominal size designation of 10x22x6/6.5 mm. It is manufactured from NBR - Nitrile Butadiene Rubber. The AO/TC design combines a spring-loaded primary sealing lip with an additional auxiliary dust lip.

For this particular variant, the complete 6/6.5 mm dimension should be retained. It should not automatically be simplified to a standard 6 mm width.

NBR 10x22x6/6.5 AO/TC - Technical Characteristics

Key identification data:

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

Design: AO/TC

Shaft diameter d: 10 mm

Housing bore diameter D: 22 mm

Construction height: 6/6.5 mm

Primary sealing lip: Yes

Garter spring: Yes

The key product identification is:

The complete dimensional designation, elastomer material and sealing-lip configuration should all be retained when selecting a replacement.

10x22x6/6.5 Oil Seal Dimensions

Nominal dimensional identification:

d = 10 mm - nominal shaft diameter

D = 22 mm - nominal housing bore diameter

Construction height = 6/6.5 mm

Complete designation:

10x22x6/6.5 mm

Unlike a straightforward 10x22x6 mm seal designation, this variant contains the dual value 6/6.5 mm.

Without a dimensional drawing for the specific manufactured seal, the additional 0.5 mm should not be arbitrarily assigned to a particular feature of the profile.

For technical identification and replacement searches, the safest approach is to retain the complete 10x22x6/6.5 mm designation.

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 and performs the main sealing function.

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

Spring-Loaded Primary Sealing Lip

The primary sealing lip operates directly against the nominal 10 mm shaft.

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

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

The garter spring acts on the primary dynamic sealing lip, not on the auxiliary dust lip.

Additional Dust Lip

The AO/TC construction incorporates an additional auxiliary dust lip.

This lip is positioned on the external side of the primary sealing arrangement.

Its main purpose is to create an additional barrier between the surrounding environment and the primary sealing lip, helping to limit the ingress of dust and other external contamination into the main sealing area.

The auxiliary lip should not be interpreted as a second identical spring-loaded primary sealing lip.

NBR - Nitrile Butadiene Rubber

Seal material:

NBR - Nitrile Butadiene Rubber

NBR is widely used as an elastomer material in rotary shaft sealing applications.

The material forms part of the complete product identification:

10x22x6/6.5 + NBR + AO/TC

A seal with identical dimensions manufactured from FKM/FPM, silicone or another elastomer represents a different material variant.

The exact NBR compound used for this seal 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 properties.

How Does a 10x22x6/6.5 Rotary Shaft Seal Work?

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

The nominal shaft diameter is:

10 mm

The nominal housing bore diameter is:

22 mm

The primary sealing lip operates dynamically against the shaft surface, while the garter spring helps maintain contact at the sealing edge.

The additional AO/TC lip creates an external protective barrier around the primary sealing area.

Actual sealing performance also depends on shaft surface condition, runout, alignment, rotational speed, temperature, lubrication, sealed medium and installation quality.

10x22x6/6.5 vs 10x22x6 Oil Seal

These two designations should not automatically be treated as the same product.

Both have:

d = 10 mm

D = 22 mm

but their third dimensional designation differs:

10x22x6/6.5: construction height = 6/6.5 mm

10x22x6: width B = 6 mm

The complete 6/6.5 mm value should therefore be retained when identifying this variant.

Without the specific manufacturer's dimensional drawing, automatic interchangeability between the two versions should not be assumed.

10x22x6/6.5 vs 10x22x5 Oil Seal

Both variants have:

d = 10 mm

D = 22 mm

but their construction heights differ:

10x22x6/6.5: 6/6.5 mm

10x22x5: 5 mm

They should therefore be treated as separate dimensional variants.

The complete third dimension should always be checked before replacement.

AO/TC vs A/SC

The principal difference is the 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, identical dimensions and NBR material alone do not establish interchangeability when the sealing-lip configuration differs.

Selection and Interchangeability

When selecting a replacement, verify:

d = 10 mm

D = 22 mm

complete 6/6.5 mm dimensional designation

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

It is particularly important not to shorten the 10x22x6/6.5 designation to 10x22x6 when searching for or specifying a replacement.

FAQ

What are the dimensions of this oil seal?

The complete dimensional designation is 10x22x6/6.5 mm, with a nominal 10 mm shaft diameter, 22 mm outside diameter and a 6/6.5 mm construction height designation.

Can this seal be described simply as 10x22x6?

It is better not to simplify it. The 6/6.5 mm value is part of the complete dimensional identification and should be retained.

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 seal made from?

It is manufactured from NBR - Nitrile Butadiene Rubber.

Is 10x22x6/6.5 the same as 10x22x6?

Not necessarily. The two products have different complete dimensional designations, so automatic interchangeability should not be assumed.

Is 10x22x6/6.5 the same as 10x22x5?

No. Although the 10 mm and 22 mm diameters are the same, their third dimensional specifications differ.

Does this seal have an additional dust lip?

Yes. The additional auxiliary dust lip is a characteristic feature of the AO/TC configuration.

Are both lips spring-loaded?

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

Engineer FAQ

What exactly does the 6/6.5 mm dimension represent?

Without a dimensional drawing for this specific seal, the exact geometrical interpretation should not be assumed. The complete 6/6.5 mm designation should be retained for technical identification.

Can a 10x22x6 seal replace a 10x22x6/6.5 seal?

Not automatically. The installation geometry and complete seal profile should be verified before substitution.

Can an exact NBR operating temperature be specified?

Not without confirmation of the exact NBR compound. Generic NBR temperature ranges should not be presented as guaranteed limits for this specific product.

Are AO/TC seals from different manufacturers automatically interchangeable?

No. Exact lip geometry, elastomer compound, spring characteristics and other construction details can differ between manufacturers.

Does D = 22 mm identify the housing bore?

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