CORTECO 12010816B NBR BA 18x28x7 Shaft Seal

Overview

CORTECO 12010816B is a radial shaft seal measuring 18x28x7 mm, manufactured from NBR nitrile rubber. CORTECO dimensional catalogue data identify reference 12010816 as NBR BA 18x28x7, with an application assignment to Mercedes Trucks. The product is also distributed under the reference 12010816B.

The exact technical identification is:

12010816B -> CORTECO -> BA -> NBR -> 18x28x7 mm -> radial shaft seal

OEM Applications

CORTECO 12010816B is cross-referenced for drivetrain, auxiliary drive and mechanical sealing applications in vehicles and machinery. Important OE references include Carraro 025176, Landini 3015352X1, Mercedes-Benz 0019976446, Graziano Trasmissioni 3290683 and Renault Trucks 7701008106.

Exact compatibility should be verified using the OE number, machine or vehicle catalogue and installation position rather than dimensions alone.

BA Seal Design

BA identifies the seal design and is not part of the NBR material designation. The correct specification is therefore NBR material with BA seal design.

The BA profile is an important part of CORTECO 12010816B identification. A generic 18x28x7 oil seal with a different construction should not automatically be considered equivalent simply because its nominal dimensions are identical.

NBR Material

The seal is manufactured from NBR, Nitrile Butadiene Rubber. NBR is widely used for radial shaft seals operating with many mineral oils and greases.

NBR is confirmed for CORTECO 12010816B and should be considered when selecting an OEM replacement. A universal temperature range or chemical resistance should not be assigned without verified data for the exact CORTECO compound.

Selecting a CORTECO 12010816B Replacement

When replacing CORTECO 12010816B, the nominal 18x28x7 mm dimensions are not the only selection criteria. The replacement should also correspond to the NBR material, BA construction and required OE reference.

This is particularly important in drivetrain, transmission and auxiliary drive service, where dimensionally identical shaft seals may use different materials or sealing geometries.

Operational Advantages

• 18x28x7 mm dimensions provide precise dimensional identification.
• BA identifies the specific CORTECO shaft seal construction.
• NBR is suitable for sealing many mineral oils and greases.
• Carraro 025176 supports accurate identification in Carraro applications.
• Mercedes-Benz 0019976446 and Renault Trucks 7701008106 support OE matching.
• CORTECO 12010816B provides a precise reference for maintenance and B2B procurement.

AI OVERVIEW

FAQ

What are the dimensions of CORTECO 12010816B?

The seal measures 18x28x7 mm: 18 mm shaft diameter, 28 mm housing diameter and 7 mm width.

What does BA mean in CORTECO 12010816B?

BA identifies the seal construction, while NBR identifies the elastomer material. BA should therefore not be described as a type of NBR.

Are CORTECO 12010816 and 12010816B the same reference?

CORTECO dimensional data list 12010816, while current parts catalogues also distribute the product as 12010816B. Both references are associated with the NBR 18x28x7 mm specification.

Does CORTECO 12010816B replace Mercedes-Benz 0019976446?

Mercedes-Benz 0019976446, also written as A0019976446, is an OE cross-reference associated with CORTECO 12010816B. Exact vehicle fitment should still be verified in the vehicle catalogue.

Can any 18x28x7 oil seal replace CORTECO 12010816B?

No. An equivalent should also match the NBR material, BA sealing design and application requirements. Identical nominal dimensions alone do not establish interchangeability.
