GRN® 170x200x15 NBR TC Double-Lip Rotary Shaft Seal

GRN® 170x200x15 NBR TC Double-Lip Rotary Shaft Seal

GRN® 170x200x15 NBR TC is a double-lip rotary shaft seal (oil seal) manufactured from NBR nitrile rubber. It has a 170 mm inside diameter, 200 mm outside diameter and 15 mm width. The TC design combines a spring-loaded primary sealing lip with an additional dust lip.

GRN® 170x200x15 NBR TC - Technical Characteristics

Dimensions

The exact dimensions are:

d = 170 mm - nominal shaft diameter

D = 200 mm - outside seal diameter

H = 15 mm - axial width

Full dimensional designation:

170x200x15 mm

All three dimensions must correspond to the shaft and housing geometry. Dimensions alone, however, are not sufficient to establish complete interchangeability.

TC Double-Lip Design

The international designation for this GRN® seal is:

TC

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

It incorporates a:

spring-loaded primary sealing lip

and an:

auxiliary dust lip.

The primary lip forms the dynamic sealing interface with the rotating shaft, while the additional lip provides an auxiliary barrier on the external side of the sealing area.

This construction distinguishes a TC double-lip oil seal from basic single-lip configurations.

Spring-Loaded Primary Sealing Lip

The primary sealing lip operates directly against the rotating shaft surface.

A garter spring supports radial contact of the sealing lip with the shaft.

The seal is therefore designed for an arrangement consisting of a:

rotating shaft

and:

stationary housing.

The suitability of the seal for a specific machine must additionally be evaluated against the actual operating medium, temperature, shaft speed and other operating conditions.

Auxiliary Dust Lip

The second lip acts as an additional external barrier.

Its function is to help limit the ingress of contaminants such as:

dust

dirt

and:

fine external particles

towards the primary sealing area.

For this reason, a 170x200x15 TC double-lip seal should not automatically be replaced by a single-lip seal solely because the installation dimensions are identical.

NBR Nitrile Rubber

The sealing material is:

NBR - nitrile butadiene rubber.

NBR is widely used for rotary shaft seals operating with many mineral oils and greases.

Compatibility must nevertheless be checked against the specific lubricant or medium used in the application, together with the actual operating temperature and shaft conditions.

A specific maximum temperature, pressure or shaft speed should not be assigned to this exact seal solely from the generic properties of NBR.

How Does the 170x200x15 Oil Seal Work?

The seal is installed between a:

rotating shaft with a nominal diameter of 170 mm

and:

stationary housing corresponding to the 200 mm outside seal diameter.

The primary spring-loaded lip runs against the shaft surface and forms the dynamic sealing interface.

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

TC vs Single-Lip Oil Seal

Rotary shaft seals with identical:

170x200x15 mm

dimensions can have different sealing configurations.

The TC version is a double-lip design.

A single-lip seal should therefore not automatically be considered an equivalent replacement for this GRN® TC seal.

The additional dust lip is part of the seal construction and may be important where the primary sealing area requires additional protection from external contamination.

Selection and Interchangeability

Before selecting GRN® 170x200x15 NBR TC, verify:

shaft diameter - 170 mm

housing bore / seal outside diameter - 200 mm

seal width - 15 mm

material - NBR

design - TC

double-lip configuration

operating medium

operating temperature

shaft speed

shaft sealing surface condition

and:

environmental conditions.

Matching 170x200x15 mm dimensions alone does not guarantee full technical interchangeability.

Technical Specification

FAQ

What are the dimensions of the GRN® 170x200x15 TC oil seal?

The exact dimensions are 170x200x15 mm: inside diameter d = 170 mm, outside diameter D = 200 mm and width H = 15 mm.

What does TC mean on this rotary shaft seal?

For this product, TC identifies the double-lip seal configuration, consisting of a spring-loaded primary sealing lip and an auxiliary dust lip.

What material is the GRN® 170x200x15 seal made from?

The seal is manufactured from NBR - nitrile butadiene rubber.

Is the GRN® 170x200x15 TC a double-lip oil seal?

Yes. It has a primary dynamic sealing lip with a garter spring and an additional dust lip.

What shaft diameter is this seal designed for?

The nominal inside diameter is 170 mm, corresponding to a nominal shaft diameter of 170 mm for the intended installation geometry.

Can a single-lip 170x200x15 seal replace this TC seal?

Interchangeability should not be assumed. The replacement should meet the application's requirements for the TC double-lip configuration, material and operating conditions.

Are all 170x200x15 oil seals interchangeable?

No. Seals with identical dimensions can differ in material, lip configuration, spring design, directional features and operating capabilities.

How should I select a 170x200x15 rotary shaft seal?

Check the 170x200x15 mm dimensions, NBR material, TC design, operating medium, temperature, shaft speed, shaft surface and environmental conditions.
