RWDR-KOMBI - Corteco Seal Design

The most important design identifier for Corteco 12018740B is:

RWDR-KOMBI

This designation is part of the technical specification of the seal and should be considered when selecting an equivalent.

The correct identification is:

148x170x14 mm + NBR + RWDR-KOMBI

A standard radial shaft seal measuring 148x170x14 mm should not automatically be considered equivalent to Corteco 12018740B.

RWDR-KOMBI vs Standard Oil Seal

The dimensions 148x170x14 mm define the basic installation size, but dimensions alone do not fully identify this product.

Corteco 12018740B uses the specific RWDR-KOMBI configuration.

For accurate replacement selection, verify:

Corteco 12018740 / 12018740B
RWDR-KOMBI design
NBR material
148x170x14 mm dimensions
DANA OE 2780603201

This is more reliable than selecting a generic oil seal by dimensions alone.

DANA 2780603201

Corteco 12018740B corresponds to:

DANA OE 2780603201

Cross reference:

DANA 2780603201 -> Corteco 12018740B -> NBR RWDR-KOMBI -> 148x170x14 mm

The DANA OE number is an important identification parameter when selecting this seal for a specific axle or assembly.

DANA / HURTH AXLE Application

Corteco dimensional catalogue data associate reference 12018740 with:

HURTH AXLE

The OE cross reference is:

DANA 2780603201

This makes the combination of the Corteco reference and DANA OE number particularly useful when identifying the correct seal for axle applications.

For a specific axle model or machine, compatibility should be verified using the OE reference.

What Does 148x170x14 Mean?

The dimensions specify:

148 mm - inside diameter
170 mm - outside diameter
14 mm - seal width

All three dimensions must match the installation.

For Corteco 12018740B, the dimensions should always be considered together with the:

RWDR-KOMBI design

and:

DANA OE 2780603201

NBR Nitrile Rubber

Corteco 12018740B is manufactured from:

NBR - Nitrile Butadiene Rubber

NBR is widely used in shaft sealing applications and offers good compatibility with many common mineral oils, greases and lubricants.

Actual suitability depends on the specific lubricant, temperature and operating conditions.

For Corteco 12018740B, the confirmed elastomer is NBR.

No Twist Design

Catalogue data specify Corteco 12018740B as:

No twist

This means the seal does not use a specified directional twist configuration.

This characteristic provides an additional identification parameter when comparing Corteco 12018740B with other shaft seals.

Corteco 12018740 vs Other 148x170x14 Seals

An oil seal with the same dimensions is not necessarily the same product.

For this Corteco reference, the relevant combination is:

12018740 -> NBR -> RWDR-KOMBI -> 148x170x14 mm

Therefore, replacement selection should not be based only on the 148 mm shaft diameter, 170 mm housing diameter and 14 mm width.

The RWDR-KOMBI design and DANA OE reference should also be verified.
