GRN® 90x160x13 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x160x13 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x160x13 NBR TC is a double lip radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 90x160x13 mm, manufactured from NBR - Nitrile Butadiene Rubber. The TC configuration combines a spring-loaded primary sealing lip with an additional auxiliary dust lip.

The principal dimensions are d: 90 mm, D: 160 mm and B: 13 mm.

Complete product identification:

GRN® + 90x160x13 mm + NBR + TC

All three dimensions should be retained when identifying this product, particularly the 160 mm outside diameter and 13 mm axial width.

GRN® 90x160x13 Dimensions

The nominal installation dimensions are:

d: 90 mm - nominal shaft diameter

D: 160 mm - nominal outside diameter / housing bore diameter

B: 13 mm - nominal axial width

Complete dimensions:

90x160x13 mm

The first dimension corresponds to the nominal shaft diameter on which the primary dynamic sealing lip operates.

The second dimension defines the nominal outside diameter of the seal and corresponding housing bore.

The third dimension specifies the axial width.

All three dimensions must be checked when selecting a replacement.

TC Double Lip Seal Design

The English design designation for this GRN® product is:

TC

TC identifies a double lip radial shaft seal configuration.

The construction incorporates:

Primary sealing lip - the main dynamic sealing element operating against the rotating shaft surface and supported by a circumferential garter spring.

Auxiliary dust lip - an additional lip positioned on the external side of the primary sealing zone.

The two sealing lips perform complementary functions.

The primary lip provides the principal dynamic sealing function, while the auxiliary lip creates an additional barrier against external contamination.

This construction is commonly described in English as a:

TC double lip oil seal

or

TC double lip rotary shaft seal

How Does the GRN® TC Oil Seal Work?

The primary sealing lip operates dynamically against the rotating shaft.

A circumferential garter spring supports radial contact between the primary sealing edge and the shaft surface.

The additional auxiliary lip is positioned toward the external environment and provides a secondary contamination barrier.

The TC construction therefore combines:

primary dynamic shaft sealing

with

additional external protection of the sealing zone

No left-hand or right-hand hydrodynamic direction is assigned to this exact GRN® variant because such directionality has not been confirmed.

NBR - Nitrile Butadiene Rubber

The specified material is:

NBR - Nitrile Butadiene Rubber

NBR is a widely used elastomer family in radial shaft sealing technology.

For this product, the material forms an integral part of the exact identification:

90x160x13 + NBR + TC

However, the designation NBR alone does not identify the exact elastomer compound used by GRN®.

Without exact product-specific documentation, no fixed values are assigned for:

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum operating pressure

Maximum rotational speed

Maximum shaft surface speed

Generic NBR parameters should not be presented as guaranteed operating limits for this exact product.

What Does 90x160x13 NBR TC Mean?

The designation can be interpreted as follows:

90 - nominal shaft diameter in mm

160 - nominal outside diameter in mm

13 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

TC - double lip seal design

GRN® - product brand

Complete identification:

GRN® + 90x160x13 + NBR + TC

For the English product page, TC should be used instead of the Polish/internal AO designation.

90 mm Shaft Diameter

The nominal shaft diameter for this seal is:

d: 90 mm

This dimension defines the nominal rotating shaft surface on which the primary sealing lip operates.

A shaft seal with a different inside diameter should not be considered dimensionally interchangeable, even if its outside diameter and width are identical.

160 mm Outside Diameter

The nominal outside diameter is:

D: 160 mm

This is a particularly important identification parameter for this product.

The difference between the outside diameter and shaft diameter is 70 mm.

This indicates a relatively large radial cross-section compared with shaft seals where the outside diameter is much closer to the shaft diameter.

However, the dimensional proportions alone should not be used to infer a specific machine or application.

13 mm Axial Width

The nominal axial width is:

B: 13 mm

This dimension distinguishes the product from other 90x160 shaft seals that may have widths such as 12 mm, 14 mm or 15 mm.

For example:

90x160x12 is not dimensionally identical to 90x160x13.

Likewise:

90x160x15 is not dimensionally identical to 90x160x13.

The complete three-dimensional specification should always be retained.

GRN® 90x160x13 vs 90x160x12

If a 90x160x12 variant is being considered, the critical difference is the axial width.

The width difference is 1 mm.

The two dimensions should therefore not be treated as identical.

Material, seal design and other construction characteristics must also be verified before considering interchangeability.

GRN® 90x160x13 vs 90x160x15

A 90x160x15 seal shares the same first two nominal dimensions but has a different axial width.

The width difference is 2 mm.

A 15 mm wide seal should therefore not automatically be considered a replacement for the 13 mm variant.

Selection and Interchangeability

When selecting a replacement for GRN® 90x160x13 NBR TC, verify at least:

• Shaft diameter d: 90 mm
• Outside diameter D: 160 mm
• Width B: 13 mm
• Material: NBR
• Design: TC
• Configuration: Double lip
• Primary lip: Spring-loaded
• Additional lip: Auxiliary dust lip

Matching only the shaft diameter and outside diameter is not sufficient.

The complete 90x160x13 mm dimensions, NBR material and TC design should be considered together.

A seal with identical dimensions but a different material or sealing design should not automatically be treated as technically interchangeable.

FAQ

What are the dimensions of GRN® 90x160x13 NBR TC?

The nominal dimensions are 90x160x13 mm, with a 90 mm shaft diameter, 160 mm outside diameter and 13 mm axial width.

Is GRN® 90x160x13 TC a double lip oil seal?

Yes. The TC design is a double lip radial shaft seal configuration.

What material is GRN® 90x160x13 TC made from?

The specified material is NBR - Nitrile Butadiene Rubber.

Does GRN® 90x160x13 TC have a dust lip?

Yes. The TC configuration incorporates an additional auxiliary dust lip.

Does the primary sealing lip have a spring?

Yes. The primary dynamic sealing lip is supported by a circumferential garter spring.

Can a 90x160x12 seal replace 90x160x13?

Direct interchangeability should not be assumed. The products differ in axial width by 1 mm.

Can a 90x160x15 seal replace 90x160x13?

Not automatically. The 15 mm variant is 2 mm wider, and its material and seal design must also be verified.

What is the operating temperature range of this NBR seal?

An exact temperature range cannot be established from the NBR designation alone. It depends on the specific elastomer compound used by the manufacturer.
