GRN 60x80x10 NBR AO/TC Oil Seal is a double lip radial shaft seal designed for a 60 mm shaft, 80 mm housing bore and 10 mm installation width. Its spring-loaded primary lip helps retain lubricant, while the auxiliary dust lip helps protect the sealing interface against external contamination. NBR provides good resistance to many mineral oils and lubricating greases, making the seal suitable for numerous industrial rotating shaft applications.
GRN 60x80x10 NBR AO/TC Oil Seal is a double lip radial shaft seal designed for a 60 mm shaft, 80 mm housing bore and 10 mm installation width. The AO/TC configuration combines a spring-loaded primary sealing lip with an auxiliary dust lip. The primary lip helps retain lubricant within the assembly, while the additional lip helps protect the sealing interface against dust and external contamination. NBR nitrile rubber provides good resistance to many mineral oils and lubricating greases.

Application: Dynamic sealing of rotating shafts
The GRN 60x80x10 NBR AO/TC uses two functional sealing lips.
The primary sealing lip operates directly against the rotating shaft. A garter spring supports radial contact between the elastomer lip and shaft surface, helping maintain the primary sealing function.
The auxiliary dust lip is positioned toward the external environment. Its function is to provide an additional barrier against dust, dirt and other external contaminants.
This double lip arrangement is useful where both lubricant retention and additional protection of the primary sealing interface are required.
The three principal installation dimensions are:
d: 60 mm
D: 80 mm
B: 10 mm
The seal is therefore designed for a 60 mm nominal shaft diameter, 80 mm housing bore and 10 mm installation width.
When selecting a replacement, all three dimensions should be checked together with the NBR material and AO/TC double lip configuration.
A different seal with the same 60x80x10 dimensions is not necessarily functionally equivalent.
NBR, or nitrile butadiene rubber, is one of the most commonly used elastomers for industrial radial shaft seals.
It provides good resistance to many:
These properties make NBR suitable for many standard mechanical and industrial sealing applications.
Final material compatibility depends on the specific operating medium, additives, temperature and actual service conditions.
A radial shaft seal creates a dynamic sealing interface between a rotating shaft and stationary housing.
In this product, the primary sealing lip remains in controlled contact with the 60 mm shaft surface. The garter spring supports the required radial contact of the lip.
The seal primarily helps:
Correct performance also depends on shaft condition, surface finish, alignment, rotational speed, temperature, lubrication and installation accuracy.
The second lip provides an additional protective barrier on the atmospheric side of the seal.
It helps reduce the ingress of:
toward the primary sealing lip.
This can be particularly beneficial in machinery where the exposed shaft area operates in an environment containing normal industrial contamination.
The auxiliary lip does not replace specialized sealing systems required for heavily contaminated operating environments.
The GRN 60x80x10 NBR AO/TC oil seal can be used in appropriately designed:
The final application should always be evaluated according to operating speed, temperature, pressure, lubricant and environmental conditions.
The 60 mm shaft diameter makes this seal relevant to appropriately dimensioned rotating assemblies in industrial drive systems.
In gearboxes and reducers, a radial shaft seal can be used at shaft exit points to help retain lubricant inside the housing.
For these applications, correct shaft surface condition and alignment are particularly important because the sealing lip operates continuously against the rotating surface.
The AO/TC configuration differs from a typical single lip seal through the presence of an additional dust protection lip.
A single lip design primarily performs the main lubricant retention function.
The AO/TC design adds another barrier between the external environment and the primary sealing interface.
A single lip 60x80x10 seal should therefore not automatically be considered an equivalent replacement where a double lip configuration is specified.
Before selecting a replacement, verify:
Shaft Diameter: 60 mm
Housing Bore: 80 mm
Width: 10 mm
Material: NBR
Design: AO / TC
Lip Configuration: Double lip
Primary Lip: Spring-loaded
Auxiliary Dust Lip: Yes
Operating Medium: Compatible with NBR
Operating Temperature: Suitable for the specific NBR compound
Shaft Speed: Appropriate for the seal and application
Matching dimensions alone do not guarantee complete interchangeability.
The condition of the 60 mm shaft surface directly influences the operation of the sealing lip.
Before installation, the contact area should be inspected for:
The sealing lip should also be protected against damage during installation, particularly when passing over shaft edges, splines, threads or keyways.
Correct installation helps prevent premature leakage and damage to the elastomer lip.
Double lip AO/TC construction: combines lubricant retention with additional contamination protection.
NBR material: provides good resistance to many mineral oils and lubricating greases.
Spring-loaded primary lip: supports controlled contact between the sealing edge and rotating shaft.
Auxiliary dust lip: helps protect the primary sealing interface against external contaminants.
60x80x10 mm dimensions: provide clear installation identification for replacement selection.
GRN identification: allows the product variant to be clearly recognized for purchasing, maintenance and warehouse replenishment.

What are the dimensions of the GRN 60x80x10 oil seal?
The seal is designed for a 60 mm shaft and 80 mm housing bore, with an installation width of 10 mm.
Is GRN 60x80x10 AO/TC a double lip oil seal?
Yes. It has a primary sealing lip and an auxiliary dust protection lip.
Does the primary sealing lip have a spring?
Yes. A garter spring supports the primary sealing lip and helps maintain contact with the rotating shaft.
Is NBR suitable for mineral oils?
NBR provides good resistance to many mineral oils and lubricating greases. Compatibility should still be verified for the specific fluid and operating temperature.
What is the function of the second lip?
The auxiliary lip helps reduce the ingress of dust, dirt and other external contaminants toward the primary sealing interface.
Is this seal designed for a 60 mm shaft?
Yes. The first dimension in 60x80x10 identifies the nominal shaft diameter of 60 mm.
Can a single lip 60x80x10 seal replace the AO/TC version?
Not automatically. A single lip design does not provide the same auxiliary dust protection as the AO/TC double lip configuration.
Is the 60x80x10 dimension sufficient to select a replacement oil seal?
No. Material, lip configuration, operating medium, temperature, shaft speed and application requirements should also be verified.
What should be inspected on the shaft before installing a new seal?
Check the sealing contact area for wear grooves, corrosion, scratches and other surface damage that could affect the sealing lip.
Does the auxiliary lip retain the oil?
The primary spring-loaded lip performs the main lubricant retention function. The auxiliary lip is primarily intended to provide additional contamination protection.
Can NBR be used with every type of oil?
No. NBR is compatible with many mineral oils and greases, but compatibility should always be checked for the specific fluid, additives and operating temperature.
Why is correct installation important for a rotary shaft seal?
A damaged lip, incorrect installation angle or unsuitable shaft surface can cause premature leakage even when the seal dimensions and material are correct.
