GRN® 90x130x13 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x130x13 NBR TC Double Lip Rotary Shaft Seal

GRN® 90x130x13 NBR TC is a double lip radial shaft seal / rotary shaft seal / oil seal with nominal dimensions of 90x130x13 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: 130 mm

B: 13 mm

Complete product identification:

GRN® + 90x130x13 mm + NBR + TC

The complete dimensional designation is important because other GRN® seals for a 90 mm shaft are available with different outside diameters and widths.

GRN® 90x130x13 NBR TC - Technical Characteristics

The principal identification parameters are:

Brand: GRN®

Product type: Radial shaft seal / rotary shaft seal / oil seal

Design: TC

Configuration: Double lip

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 90x130x13 mm

Shaft diameter d: 90 mm

Outside diameter D: 130 mm

Width B: 13 mm

Primary sealing lip: Spring-loaded

Additional lip: Auxiliary dust lip

For precise technical identification, retain:

GRN® + 90x130x13 + NBR + TC

GRN® 90x130x13 Dimensions

The nominal installation dimensions are:

d: 90 mm - nominal shaft diameter

D: 130 mm - nominal outside diameter / housing bore diameter

B: 13 mm - nominal axial width

Complete dimensions:

90x130x13 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 identifying a replacement.

TC Double Lip Seal Design

The design designation 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.

Garter spring - supports radial contact between the primary sealing edge and the shaft surface.

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

The primary lip performs the principal dynamic sealing function, while the auxiliary lip provides additional protection against external contamination.

This configuration is commonly described 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 surface with a nominal diameter of 90 mm.

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

The auxiliary lip provides an additional barrier between the main sealing zone and the external environment.

The TC configuration therefore combines dynamic shaft sealing with additional protection of the sealing area.

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 sealing material is:

NBR - Nitrile Butadiene Rubber

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

For this product, the material forms part of the complete identification:

90x130x13 + NBR + TC

However, the NBR designation alone does not identify the exact elastomer compound used in this specific GRN® seal.

Without product-specific documentation, no fixed values should therefore be assigned for:

Shore A hardness

Minimum operating temperature

Maximum operating temperature

Maximum operating pressure

Maximum rotational speed

Maximum shaft surface speed

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

What Does 90x130x13 NBR TC Mean?

The designation can be interpreted as follows:

90 - nominal shaft diameter in mm

130 - 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® + 90x130x13 + NBR + TC

90 mm Shaft Diameter

The nominal shaft diameter is:

d: 90 mm

This is the nominal rotating surface on which the primary sealing lip operates.

A 90 mm inside diameter alone is not sufficient to identify the correct shaft seal because multiple outside diameters and widths may be available for the same nominal shaft size.

130 mm Outside Diameter

The nominal outside diameter is:

D: 130 mm

This is a particularly important identification parameter for this product.

Other GRN® variants may also use a 90 mm shaft diameter but have outside diameters of 140 mm or 160 mm.

Therefore:

90x130x13

must not be simplified to a generic "90 mm oil seal".

GRN® 90x130x13 vs GRN® 90x140x13

These variants share the same shaft diameter and axial width but differ in outside diameter.

The critical difference is:

D: 130 mm vs D: 140 mm

The outside diameter differs by 10 mm.

The two products are therefore not dimensionally identical and should remain separate product references.

GRN® 90x130x13 vs GRN® 90x140x12

There are two dimensional differences between these variants:

The differences are:

Outside diameter: 130 mm vs 140 mm

Width: 13 mm vs 12 mm

These are distinct dimensional variants.

GRN® 90x130x13 vs GRN® 90x160x13

Both variants have:

d: 90 mm

B: 13 mm

However, their outside diameters differ substantially:

GRN® 90x130x13 - D: 130 mm

GRN® 90x160x13 - D: 160 mm

The difference is 30 mm.

They are not dimensionally interchangeable.

Why Is the 130 mm Outside Diameter Important?

When searching for a shaft seal, the shaft diameter is often used as the first selection parameter.

However, a 90 mm shaft diameter alone does not identify this seal.

For this product, the complete dimensions are:

90x130x13 mm

The 130 mm outside diameter distinguishes it from other GRN® variants designed for a 90 mm shaft, including:

90x140x13

90x140x12

90x160x13

The complete three-dimensional specification should always be retained during product selection.

Selection and Interchangeability

When selecting a replacement for GRN® 90x130x13 NBR TC, verify at least:

• Shaft diameter d: 90 mm
• Outside diameter D: 130 mm
• Width B: 13 mm
• Material: NBR
• Design: TC
• Configuration: Double lip
• Primary sealing lip: Spring-loaded
• Additional lip: Auxiliary dust lip

Matching the 90 mm shaft diameter alone is not sufficient.

A 90x140x13 seal has an outside diameter 10 mm larger, while a 90x160x13 seal has an outside diameter 30 mm larger.

A product with identical dimensions but a different elastomer or sealing design should also not automatically be considered technically interchangeable.
