Rotary Shaft Seal GRN 17x35x12 TC NBR Oil Seal - Double Lip

GRN 17x35x12 TC NBR Oil Seal - Double Lip

GRN® 17x35x12 TC NBR is a double-lip rotary shaft oil seal manufactured from nitrile rubber (NBR). It has a 17 mm shaft diameter, 35 mm outside diameter and 12 mm width. The TC design incorporates a primary sealing lip and an additional dust lip that helps protect the sealing area against external contamination.

Technical Data

17x35x12 mm Dimensions

The designation 17x35x12 defines the principal dimensions of the oil seal:

• 17 mm - shaft diameter

• 35 mm - outside diameter

• 12 mm - seal width

Complete product identification:

GRN® 17x35x12 TC NBR

All three dimensions should be verified before selecting the oil seal for a specific housing and shaft.

NBR - Nitrile Rubber

The seal is manufactured from NBR - nitrile butadiene rubber, one of the most commonly used elastomers for rotary shaft seals.

NBR provides good resistance to many:

• mineral oils

• lubricating greases

• mineral-oil-based fluids

For this reason, NBR oil seals are widely used in machinery, drives, gearboxes, motors and other mechanisms with rotating shafts.

Material compatibility should always be checked against the specific operating medium and actual working conditions.

TC - Double-Lip Oil Seal Design

The GRN 17x35x12 uses a double-lip design identified internationally as:

TC

The seal incorporates:

• a primary sealing lip

• an additional dust lip

The primary lip provides the main sealing function against the rotating shaft.

The additional lip helps limit the ingress of dust, dirt and other external contaminants into the primary sealing area.

AO / TC Profile Designations

Rotary shaft seal profile designations are not completely standardized between manufacturers and markets.

The designation:

AO

is encountered in European technical terminology for this type of double-lip construction.

The designation:

TC

is widely used internationally for a double-lip rotary shaft oil seal with a rubber-covered outside diameter, primary sealing lip and additional dust lip.

For international searches, this product can therefore be identified primarily as:

17x35x12 TC NBR Oil Seal

Alternative search terminology may include:

17x35x12 AO NBR

When comparing products from different manufacturers, the actual seal construction should always be verified rather than relying only on the profile code.

GRN® 17x35x12 Oil Seal

GRN® technical seals have been included in the TG Ersatzteile Polska product range since 2007.

The:

17x35x12 TC NBR

version combines a standard rotary shaft seal size with a double-lip construction and NBR elastomer.

It is intended for industrial users, maintenance departments, workshops and B2B customers selecting rotary shaft seals by dimensions, material and profile.

Applications

GRN 17x35x12 TC NBR is designed for radial sealing of rotating shafts in appropriately designed machinery and mechanical assemblies.

The double-lip construction is useful where the primary sealing function is combined with additional protection against external contamination.

Suitability for a specific application depends on:

• operating medium

• operating temperature

• shaft speed

• pressure

• shaft surface condition

• housing design

• environmental conditions

17x35x12 vs 17x35x10 - Important Difference

A:

17x35x12

oil seal should not automatically be replaced with a:

17x35x10

oil seal.

Both products have the same 17 mm shaft diameter and 35 mm outside diameter, but their widths differ:

• 17x35x12 - width 12 mm

• 17x35x10 - width 10 mm

The 2 mm difference may affect the position of the sealing lip on the shaft, installation depth and overall compatibility with the sealing arrangement.

How to Select a 17x35x12 Oil Seal

Before purchasing, verify:

1. Shaft diameter 17 mm.

2. Housing bore diameter 35 mm.

3. Width 12 mm.

4. NBR material.

5. TC double-lip construction.

6. Presence of the additional dust lip.

7. Operating medium.

8. Operating temperature.

9. Shaft speed.

10. Actual operating conditions.

Matching the 17x35x12 mm dimensions alone is not sufficient to confirm full interchangeability.

Installation

Before installation:

• thoroughly clean the shaft and housing bore

• inspect the shaft sealing surface

• remove dirt, corrosion and burrs

• protect the sealing lip from sharp edges

• protect the lip when passing over threads and grooves

• use an appropriate installation tool

• press the seal evenly into the housing

• avoid deformation of the seal body

• verify the correct installation orientation

The condition of the shaft surface and correct installation directly affect sealing performance and service life.

FAQ

What are the dimensions of the GRN 17x35x12 oil seal?

The seal has a 17 mm shaft diameter, 35 mm outside diameter and 12 mm width.

What material is the GRN 17x35x12 oil seal made from?

It is manufactured from NBR - nitrile rubber.

Is the GRN 17x35x12 TC oil seal double-lip?

Yes. The TC construction incorporates a primary sealing lip and an additional dust lip.

What does TC mean on an oil seal?

TC is a widely used international designation for a double-lip rotary shaft oil seal with a primary sealing lip and an additional dust lip.

What does NBR mean?

NBR stands for nitrile butadiene rubber, one of the most commonly used elastomers in rotary shaft seals.

Is NBR suitable for oil?

NBR provides good resistance to many mineral oils and lubricating greases. Compatibility should nevertheless be checked against the specific fluid and operating conditions.

Are AO and TC the same?

AO and TC are profile designations encountered in different seal nomenclature systems for similar double-lip constructions. Because profile codes are not fully standardized between manufacturers, the actual construction should always be checked when selecting an equivalent.

Can a 17x35x10 oil seal replace a 17x35x12 oil seal?

Not automatically. The seals differ in width by 2 mm, which may affect installation depth and the position of the sealing lip on the shaft.

Are all 17x35x12 oil seals interchangeable?

No. Oil seals with identical dimensions can differ in elastomer, lip configuration, outer diameter construction and operating characteristics.
