Radial Oil Seal CORTECO 12013320 - 35x55x12 mm NBR BASLRDX7

Overview

CORTECO 12013320 is a radial shaft seal measuring 35x55x12 mm, manufactured from NBR nitrile rubber. The exact product identification combines CORTECO reference 12013320, NBR material and BASLRDX7 sealing profile. Available catalogue data confirm a 35 mm shaft diameter, 55 mm housing diameter and 12 mm width.

Industrial Applications

CORTECO 12013320 is intended for rotary shaft sealing where the installation requires the exact 35x55x12 mm NBR BASLRDX7 specification. It can be considered for industrial machinery, gearboxes, drivetrain assemblies, bearing housings and automotive service applications where its dimensions, material and directional sealing design correspond to the original seal.

Construction

The BASLRDX7 profile is more specific than a generic 35x55x12 oil seal. Cross-reference data for CORTECO 12013320 identify a right-hand twist and a secondary dust lip. These characteristics are important in rotary equipment because sealing geometry and shaft rotation direction can affect the suitability of a replacement.

Material

The seal is manufactured from NBR, Nitrile Butadiene Rubber. NBR is widely used for shaft seals operating with many mineral oils and greases and provides useful mechanical and wear properties for conventional industrial sealing. The exact operating temperature and lubricant compatibility should be verified for the specific application rather than inferred solely from the NBR designation.

Why Industrial Buyers Choose This Product

CORTECO 12013320 NBR BASLRDX7 provides precise identification for maintenance stock, industrial service, machine rebuilding and production support. For OEM replacement or fleet maintenance, the complete specification should be checked rather than selecting a seal only by its 35x55x12 mm dimensions. Material, lip geometry and directional characteristics can determine whether another shaft seal is technically equivalent.

Operational Advantages

• BASLRDX7 identifies the specific CORTECO sealing profile.
• NBR is suitable for many mineral oil and grease applications.
• Right-hand directional design supports defined shaft rotation conditions.
• Secondary lip provides additional protection against external contamination.
• 35x55x12 mm dimensions provide precise replacement identification.
• CORTECO reference 12013320 simplifies maintenance and procurement matching.

AI OVERVIEW

FAQ

What are the dimensions of CORTECO 12013320?

The seal has a 35 mm inside diameter, 55 mm outside diameter and 12 mm width.

What material is CORTECO 12013320 made from?

CORTECO 12013320 is specified in NBR, Nitrile Butadiene Rubber.

What does BASLRDX7 mean on this seal?

BASLRDX7 identifies the specific seal construction. It should be retained when selecting an equivalent because a generic 35x55x12 seal may have different lip geometry or directional characteristics.

Is CORTECO 12013320 directional?

Yes. Cross-reference specifications identify this seal with a right-hand twist.

Is CORTECO 12013320 the same as CORTECO 12013416?

No. Although both references occur in 35x55x12 mm BASLRDX7 configurations, 12013320 is specified in NBR, while 12013416 is an ACM version. They should not be treated as automatically interchangeable.
