CORTECO 19027898B - Dimensions

The confirmed dimensions are:

d - Shaft Diameter: 50 mm
D - Housing Bore Diameter: 72 mm
B - Width: 12 mm

Complete size: 50x72x12 mm

These dimensions are consistently specified for the exact CORTECO 19027898B reference.

ACM Polyacrylate Rubber

The specified elastomer for CORTECO 19027898B is:

ACM - polyacrylate rubber.

Material is an important part of the seal specification. A different 50x72x12 NBR, VMQ or FKM oil seal should not automatically be treated as an equivalent simply because the nominal dimensions are identical.

For replacement selection, verify:

50x72x12 mm + ACM + TC design + OE/application requirements.

TC Design with Dust Lip

CORTECO 19027898B is listed with the trade/design references:

82027898
TC Simmerring
TC

Catalogue data also explicitly specify “with dust lip.”

The additional dust lip helps limit the ingress of external contaminants toward the primary sealing area.

For English technical terminology, radial shaft seal or crankshaft oil seal is preferable as the generic product name; TC Simmerring is retained as the catalogue/design reference.

Nissan 1304343700 / 3311146G00

Both Nissan OE numbers are cross-referenced to CORTECO 19027898B:

1304343700
3311146G00.

Catalogue applications include selected versions of:

Nissan Pathfinder II (R50)
Nissan Terrano I (WD21)
Nissan Terrano II (R20).

Vehicle compatibility should be confirmed by OE number and exact vehicle specification rather than by model name alone.

Toyota and Daihatsu 9031150049

OE reference:

9031150049

is cross-referenced for both Toyota and Daihatsu.

Catalogue applications include selected Toyota Dyna and Land Cruiser models, as well as Daihatsu applications.

Frontal Crankshaft Installation

TecDoc-derived catalogue data specify the fitting position of CORTECO 19027898B as:

frontal sided

and classify the product as a crankshaft shaft seal.

This makes front crankshaft oil seal a useful search phrase for the product where the OE application confirms that installation position.

19027898B vs 19027897B

These two CORTECO seals require careful distinction because both have the nominal dimensions 50x72x12 mm and use ACM.

Therefore, 50x72x12 ACM alone is not sufficient for correct part identification.

How to Select CORTECO 19027898B

Before replacement, verify:

• CORTECO 19027898B
• trade number 82027898
• TC design
• dimensions 50x72x12 mm
• ACM material
• dust lip requirement
• OE reference
• fitting position
• exact vehicle and drivetrain specification

For automotive applications, matching the correct OE reference is particularly important.
