GRN 115x140x13 NBR TC Double Lip Rotary Shaft Seal

GRN 115x140x13 NBR TC is a double-lip rotary shaft seal with an inside diameter of 115 mm, outside diameter of 140 mm and width of 13 mm. The seal is manufactured from NBR (nitrile butadiene rubber) and uses the TC double-lip configuration, combining the primary sealing lip with an additional dust lip.

GRN 115x140x13 NBR TC - Characteristics

The exact product identity is:

GRN -> 115x140x13 mm -> NBR -> TC -> double-lip rotary shaft seal -> dust lip

This combination is important when identifying the seal. A product with the same 115x140x13 mm dimensions but a different material or lip configuration is not automatically the same technical specification.

The GRN product is specifically listed as 115x140x13 NBR TC Oil Seal Double Lip.

Dimensions

The confirmed dimensions are:

Shaft / Inside Diameter: 115 mm
Housing / Outside Diameter: 140 mm
Width: 13 mm
Complete Size: 115x140x13 mm

These dimensions are confirmed for the exact GRN product.

The first dimension identifies the nominal shaft diameter, the second the nominal housing bore diameter and the third the seal width.

TC Double-Lip Construction

The TC designation identifies this product as a double-lip radial shaft seal. The construction combines a primary sealing lip with an additional protective or dust lip. Independent technical catalogues also identify TC 115x140x13 as a double-lip NBR oil-seal configuration.

The primary lip forms the dynamic sealing interface with the rotating shaft. The additional lip is positioned toward the external side and helps restrict contaminants from reaching the primary sealing area.

This distinction is important when comparing the TC version with a corresponding single-lip seal.

NBR Material

The sealing element is manufactured from NBR - nitrile butadiene rubber. The exact GRN product page confirms NBR as the material for this 115x140x13 mm TC seal.

NBR is widely used for radial shaft seals because of its useful mechanical properties and resistance to many mineral-oil-based oils and greases. The GRN technical information also identifies compatibility with several common oil and grease media while noting limitations with, among others, aromatic and chlorinated hydrocarbons and glycol-based brake fluids.

Material compatibility should always be checked against the actual lubricant, fluid and operating conditions.

Primary Sealing Lip and Dust Lip

The two lips of the GRN 115x140x13 NBR TC perform different functions.

The primary sealing lip operates against the rotating shaft and provides the principal dynamic sealing function.

The additional dust lip provides a secondary external barrier that helps limit the entry of dirt and other contaminants toward the primary sealing zone.

The presence of the dust lip is explicitly confirmed for the exact GRN 115x140x13 product.

Radial Shaft Sealing

GRN 115x140x13 NBR TC belongs to the group of radial shaft seals, also commonly described as rotary shaft seals or oil seals.

The seal is installed between a rotating shaft and stationary housing. For this reference, the nominal shaft diameter is 115 mm and the nominal housing bore diameter is 140 mm.

Unlike the CORTECO 20029785 discussed for the same nominal size, this GRN product is identified as a general NBR TC double-lip radial shaft seal rather than a PTFE directional crankshaft seal associated with a specific OE application.

GRN 115x140x13 NBR TC vs Single-Lip Seal

A single-lip and double-lip seal with identical dimensions should not automatically be considered the same product.

The GRN 115x140x13 NBR TC has an additional dust lip. Therefore, when replacing an existing seal, the required lip configuration should be checked in addition to the three nominal dimensions.

This is particularly important where the original sealing position requires additional protection of the primary sealing zone from external contamination.

Selection and Interchangeability

When selecting a replacement for GRN 115x140x13 NBR TC, compare:

• inside / shaft diameter: 115 mm
• outside / housing diameter: 140 mm
• width: 13 mm
• material: NBR
• design: TC
• construction: double lip
• additional dust lip
• actual operating medium and conditions

A dimensional match of 115x140x13 mm alone does not establish complete technical interchangeability.

For example, a 115x140x13 mm PTFE directional crankshaft seal and a 115x140x13 mm NBR TC general-purpose radial shaft seal have the same nominal dimensions but fundamentally different technical identities.

FAQ

What are the dimensions of GRN 115x140x13 NBR TC?

The seal measures 115x140x13 mm: 115 mm inside diameter, 140 mm outside diameter and 13 mm width.

What type of seal is GRN 115x140x13?

It is an NBR TC double-lip rotary shaft seal, also described as a radial shaft seal or oil seal.

What does TC mean in this GRN oil seal?

For this product, TC identifies the double-lip configuration, incorporating the primary sealing lip and an additional protective dust lip.

What material is the GRN 115x140x13 TC seal made from?

It is manufactured from NBR - nitrile butadiene rubber.

Does GRN 115x140x13 NBR TC have a dust lip?

Yes. The exact GRN product is specified as a shaft seal with a dust lip.

What shaft diameter is this seal designed for?

Its nominal inside diameter is 115 mm, corresponding to a nominal 115 mm shaft size.

What housing bore corresponds to this seal?

The nominal outside diameter is 140 mm, corresponding to the housing bore dimension used for seal selection.

Can any 115x140x13 oil seal replace this GRN TC seal?

Not automatically. In addition to dimensions, verify the NBR material, TC double-lip construction, dust lip and compatibility with the actual operating conditions.
