GRN® 265x290x16 NBR Oil Seal – Technical Characteristics

The GRN® 265x290x16 is a large-diameter radial shaft seal designed for rotating shaft applications where the required specification corresponds to:

265x290x16 mm

NBR

AO/TC

double-lip construction

additional dust lip

All these parameters should be considered when selecting a replacement.

Matching the dimensions alone does not confirm complete technical interchangeability.

265x290x16 Oil Seal Dimensions

Exact nominal dimensions:

The correct international dimensional designation is:

265x290x16 mm

The 265 mm inside diameter corresponds to the nominal shaft diameter, while the 290 mm outside diameter corresponds to the nominal seal housing diameter.

AO/TC Double-Lip Oil Seal Design

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

The construction incorporates:

Primary sealing lip – the main sealing element acting on the rotating shaft.

Auxiliary dust lip – an additional lip located on the external side of the primary sealing area.

This auxiliary lip distinguishes the AO/TC double-lip design from the corresponding single-lip A/SC configuration.

For international technical searches, the common designation is:

TC oil seal 265x290x16

while the GRN® product designation is:

AO/TC 265x290x16

NBR – Nitrile Butadiene Rubber

The sealing material is:

NBR – Nitrile Butadiene Rubber

NBR is widely used for radial shaft seals operating with many common oils and lubricants.

However, compatibility should always be verified for the actual medium and operating conditions of the machine.

A universal temperature, pressure or maximum shaft-speed value should not be assigned to this specific GRN® seal without the corresponding compound-specific technical data.

Large-Diameter 265 mm Rotary Shaft Seal

With a nominal shaft diameter of 265 mm, this product belongs to the category of large-diameter rotary shaft seals.

Large oil seals of this type are used in industrial rotating equipment when the machine requires the corresponding dimensions, material and sealing-lip configuration.

The product may be relevant for industrial maintenance, machinery repair, MRO departments, workshops and equipment manufacturers requiring an exact:

265x290x16 NBR double-lip oil seal

The seal should not, however, be assigned to a particular gearbox, pump, motor or machine solely on the basis of its dimensions.

Additional Dust Lip

The second lip in the AO/TC construction acts as an:

auxiliary dust lip

It creates an additional barrier between the primary sealing area and the external environment.

This feature is important when comparing the product with other 265x290x16 mm rotary shaft seals.

A single-lip seal with identical dimensions should not automatically be considered equivalent to this double-lip AO/TC version.

AO/TC vs A/SC 265x290x16

Rotary shaft seals with identical dimensions may be available in different lip configurations.

265x290x16 AO/TC – double-lip design with an additional auxiliary/dust lip.

265x290x16 A/SC – single-lip design without the additional dust lip.

The correct version should be selected according to the original seal specification and operating requirements.

Therefore:

265x290x16 AO/TC ≠ automatically interchangeable with 265x290x16 A/SC

even though their nominal dimensions may be identical.

How to Select a 265x290x16 Replacement Oil Seal

When selecting a replacement for GRN® 265x290x16 NBR AO/TC, verify at least:

Shaft diameter: 265 mm

Housing diameter: 290 mm

Seal width: 16 mm

Material: NBR

Profile: AO/TC

Construction: Double lip

Auxiliary dust lip: Yes

The complete technical identification is therefore:

265x290x16 + NBR + AO/TC + double lip

Dimensions alone should not be used as the only interchangeability criterion.
