GRN® 35x52x10 NBR BASL Rotary Shaft Seal with Dust Lip

GRN® 35x52x10 NBR BASL Rotary Shaft Seal with Dust Lip

GRN® 35x52x10 NBR BASL is a radial shaft seal / rotary shaft seal / oil seal with an auxiliary dust lip, manufactured from NBR - Nitrile Butadiene Rubber. Its nominal dimensions are 35x52x10 mm. The BASL profile incorporates a spring-loaded primary dynamic sealing lip and an additional protective lip on the external side of the sealing system.

Complete technical identification:

GRN® + 35x52x10 + NBR + BASL

GRN® 35x52x10 NBR BASL - Technical Characteristics

The principal identification parameters are:

Brand: GRN®

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

Profile: BASL

Material: NBR

Material name: Nitrile Butadiene Rubber

Dimensions: 35x52x10 mm

Shaft diameter d: 35 mm

Outside diameter D: 52 mm

Width B: 10 mm

Primary sealing lip: Spring-loaded

Additional lip: Auxiliary dust lip

For precise product identification, retain:

GRN® + 35x52x10 + NBR + BASL

The dimensions alone do not fully identify the product because other 35x52x10 shaft seals may use different materials, lip configurations or profile designs.

GRN® 35x52x10 Dimensions

The nominal installation dimensions are:

d: 35 mm - nominal shaft diameter

D: 52 mm - nominal seal outside diameter / housing bore diameter

B: 10 mm - nominal axial width

Complete dimensions:

35x52x10 mm

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

The second defines the nominal outside diameter of the seal installed in the housing.

The third specifies the nominal axial width.

All three dimensions must be checked when identifying or selecting a replacement.

BASL Seal Profile with Auxiliary Dust Lip

The key construction designation for this product is:

BASL

The BASL profile incorporates:

Primary sealing lip - the 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 auxiliary lip should not be interpreted as a second identical oil-retaining lip. Its principal function is to protect the primary sealing area against external contamination.

For this reason, an accurate English description is:

Radial Shaft Seal with Auxiliary Dust Lip

or

Rotary Shaft Seal with Dust Lip

The BASL profile designation should remain in the product name because it provides more precise technical identification than the generic phrase “double lip oil seal”.

BASL vs TC - Important Identification Difference

BASL and TC should not automatically be treated as identical profile designations.

Both terms may describe radial shaft seal constructions incorporating a primary spring-loaded sealing lip and an auxiliary protective lip, but profile nomenclature varies between manufacturers and product systems.

For this specific product, the supplied technical designation is:

BASL

Therefore, the English product card retains BASL rather than replacing the exact profile designation with TC.

This helps prevent the product from being incorrectly merged with generic 35x52x10 NBR TC seals in search engines, marketplaces and AI-generated product comparisons.

How Does the GRN® 35x52x10 BASL Seal Work?

The primary dynamic sealing lip operates against a shaft with a nominal diameter of 35 mm.

The garter spring supports contact between the primary sealing edge and the shaft surface. During shaft rotation, this lip forms the principal dynamic sealing interface.

The auxiliary dust lip is positioned toward the external side of the seal. It creates an additional barrier against dust and other contaminants entering the primary sealing zone.

The two lips therefore perform different functions:

Primary lip - dynamic shaft sealing

Auxiliary lip - external contamination protection

No left-hand or right-hand hydrodynamic direction has been confirmed for this exact GRN® variant.

NBR - Nitrile Butadiene Rubber

The sealing material is:

NBR - Nitrile Butadiene Rubber

NBR is an integral part of the technical identification:

35x52x10 + NBR + BASL

A shaft seal with identical 35x52x10 mm dimensions but manufactured from FPM, VMQ or another elastomer should not automatically be treated as the same technical product.

For the exact GRN® 35x52x10 NBR BASL, product-specific values have not been confirmed 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 therefore not be presented as guaranteed specifications for this exact product.

What Does 35x52x10 NBR BASL Mean?

The designation can be interpreted as follows:

35 - nominal shaft diameter in mm

52 - nominal outside diameter in mm

10 - nominal axial width in mm

NBR - Nitrile Butadiene Rubber

BASL - radial shaft seal profile with spring-loaded primary sealing lip and auxiliary dust lip

GRN® - product brand

Complete technical identification:

GRN® + 35x52x10 + NBR + BASL

This complete designation is more precise than searching only for a 35x52x10 oil seal.

GRN® 35x52x10 NBR BASL vs Other 35x52x10 Seals

The nominal dimensions:

35x52x10 mm

do not establish complete technical equivalence.

Shaft seals with identical dimensions can differ in:

elastomer material

sealing lip geometry

presence or absence of a dust lip

outside diameter construction

hydrodynamic features

directionality

application-specific design

For this reason, the complete search and identification phrase should remain:

GRN® 35x52x10 NBR BASL

This helps distinguish the product from other 35x52x10 seals and reduces search cannibalization between technically different variants.

Selection and Interchangeability

When selecting a replacement for GRN® 35x52x10 NBR BASL, verify at least:

• Shaft diameter d: 35 mm
• Outside diameter D: 52 mm
• Width B: 10 mm
• Material: NBR
• Profile: BASL
• primary sealing lip construction
• presence of the garter spring
• presence of the auxiliary dust lip
• any directional or hydrodynamic features of the compared seal

Identical 35x52x10 mm dimensions do not automatically establish full technical interchangeability.

A CORTECO, SKF, Simrit or another manufacturer's seal should not be treated as a direct replacement solely because its dimensions match.

Material, lip geometry, profile design and any application-specific requirements must also be verified.

Technical Specification

FAQ

What are the dimensions of GRN® 35x52x10 NBR BASL?

The nominal dimensions are d: 35 mm, D: 52 mm, B: 10 mm.

What type of seal is GRN® 35x52x10 BASL?

It is a radial shaft seal / rotary shaft seal with an auxiliary dust lip, manufactured from NBR.

What does BASL mean on this GRN® shaft seal?

BASL identifies the seal profile incorporating a spring-loaded primary sealing lip and an additional protective dust lip.

Does GRN® 35x52x10 BASL have a dust lip?

Yes. The construction incorporates an auxiliary dust lip on the external side of the primary sealing zone.

Is BASL the same as TC?

They should not automatically be treated as identical designations. Both can describe constructions with a primary sealing lip and auxiliary lip, but profile terminology varies between manufacturers. The exact BASL designation should therefore be retained for this product.

Is GRN® 35x52x10 NBR BASL a double lip seal?

It incorporates two functional lips: a spring-loaded primary dynamic sealing lip and an auxiliary dust lip. The two lips perform different functions.

Can another 35x52x10 oil seal replace this GRN® product?

Not automatically. Dimensions, NBR material, BASL profile, lip configuration and any directional or application-specific features must be verified.

Is GRN® 35x52x10 NBR BASL directional?

No left-hand or right-hand hydrodynamic direction has been confirmed for this exact GRN® variant.
