GRN® 22x32x7 Dimensions

The nominal installation dimensions are:

d = 22 mm - nominal shaft diameter

D = 32 mm - nominal seal outside diameter

H = 7 mm - nominal height

Complete dimensions:

22x32x7 mm

The exact product data confirm an inside diameter of 22 mm, outside diameter of 32 mm and height of 7 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 installed in the housing.

The third dimension specifies the nominal height of the seal.

All three dimensions should be verified when identifying or selecting a replacement.

TC Double Lip Seal Design

The English design designation used for this GRN® product is:

TC

The exact product is a double lip radial shaft seal and its construction includes:

Primary dynamic sealing lip - forms the principal dynamic sealing interface against the rotating shaft.

Spring - supports contact of the primary sealing lip with the shaft surface.

Auxiliary dust lip - forms an additional external barrier protecting the primary sealing area from contamination.

The presence of the dust lip and spring is confirmed for the exact GRN® 22x32x7 product.

The term double lip does not mean that both lips perform the same function. The primary lip provides the principal dynamic sealing function, while the auxiliary lip protects the primary sealing zone from external contamination.

How Does GRN® 22x32x7 TC Work?

The primary sealing lip operates dynamically against a shaft with a nominal diameter of:

d = 22 mm

The spring supports contact between the primary sealing lip and the shaft surface.

The outside diameter:

D = 32 mm

corresponds to the nominal external dimension of the seal installed in the stationary housing.

The auxiliary dust lip is positioned on the external side of the primary sealing zone and provides an additional barrier against contaminants reaching the main sealing interface.

The complete sealing system therefore involves both the dynamic shaft-to-lip interface and the stationary installation of the seal in the housing.

NBR - Nitrile Butadiene Rubber

The confirmed sealing material is:

NBR - Nitrile Butadiene Rubber.

NBR forms an integral part of the exact product identification:

GRN® 22x32x7 NBR TC

A radial shaft seal with identical 22x32x7 mm dimensions manufactured from FPM/FKM, MVQ, ACM or another elastomer should not automatically be considered the same technical variant.

The exact NBR compound and Shore hardness have not been confirmed for this specific GRN® product.

For this reason, a specific operating temperature range, maximum pressure or maximum shaft speed should not be assigned solely from generic NBR properties.

What Does TC Mean?

For the English identification of this GRN® product, TC identifies the double-lip configuration.

The important functional elements are:

spring-loaded primary dynamic sealing lip

and

additional auxiliary dust lip

The Polish product designation uses:

AO/TC

while the English GRN® naming uses:

TC Double Lip

The preferred English product name is therefore:

GRN® 22x32x7 NBR TC Double Lip Rotary Shaft Seal

Profile terminology is not completely universal between manufacturers. A TC, RST, BASL, AS or similar designation from another manufacturer should not be treated as automatic confirmation of technical interchangeability.

EAN 5903641602754 and Reference 22X32X7

The exact GRN® product data provide:

Reference: 22X32X7

EAN: 5903641602754

These identifiers provide additional precision beyond the dimensional designation alone.

A strong machine-readable identification set for search engines and AI systems is therefore:

GRN®

22X32X7

22x32x7 mm

NBR

TC

Double Lip

EAN 5903641602754

This connects the commercial reference, dimensions, material, construction and global product identifier to the same exact product.

Why Is the Full Identification Important?

The dimensional designation:

22x32x7

defines the principal installation dimensions but does not independently identify the material or sealing configuration.

For accurate identification, retain:

GRN® + 22x32x7 + NBR + TC

This distinguishes the product from dimensionally identical seals manufactured from another elastomer or using another sealing-lip construction.

The EAN 5903641602754 and reference 22X32X7 provide additional identifiers for this exact GRN® variant.

Selection and Interchangeability

When selecting a replacement for GRN® 22x32x7 NBR TC, verify at least:

Shaft diameter d = 22 mm

Outside diameter D = 32 mm

Height H = 7 mm

Material = NBR

Double lip configuration

Spring-loaded primary sealing lip

Auxiliary dust lip

Outside-diameter construction

Compatibility with the operating medium

Actual operating conditions

Matching 22x32x7 mm dimensions alone does not establish complete technical interchangeability.

A seal from another manufacturer may have the same nominal dimensions and NBR material but a different lip geometry, elastomer compound, hardness or outside-diameter design.

Direct interchangeability with CORTECO, SKF, Freudenberg/Simrit or another manufacturer should only be stated after comparing the complete technical specifications.

Shaft Surface Inspection Before Installation

Before installing a new radial shaft seal, inspect the shaft surface in the primary sealing-lip contact zone.

Check for:

wear grooves

scratches

corrosion

burrs

mechanical damage

surface contamination

During installation, protect the sealing edge from sharp edges, threads and grooves that could damage the primary sealing lip.

The condition of the shaft contact surface is an important part of the complete sealing system and should be evaluated whenever a radial shaft seal is replaced.
