CORTECO 19019964 18.7x35x7 NBR BASLSF Simmerring® Radial Shaft Seal

CORTECO 19019964 18.7x35x7 NBR BASLSF Simmerring® Radial Shaft Seal

CORTECO 19019964 is a Simmerring® radial shaft seal with nominal dimensions 18.7x35x7 mm, manufactured from NBR and identified by the CORTECO profile BASLSF. The reference is listed in CORTECO catalogue data within the power steering seal range.

The complete technical identity is:

CORTECO + 19019964 + 18.7x35x7 + NBR + BASLSF

CORTECO 19019964 – Technical Characteristics

CORTECO 19019964 Dimensions

The nominal dimensions are:

d: 18.7 mm – shaft diameter

D: 35 mm – outside diameter

B: 7 mm – nominal width

Complete dimensional designation:

18.7x35x7 mm

The 18.7 mm shaft diameter is particularly important when identifying this seal. It should not be rounded to 18 mm or 19 mm when searching for a replacement.

Some catalogue material also shows the dimensional notation 18.7x35x7/7.5 mm. The primary product designation remains 18.7x35x7 mm, while the additional 7.5 mm value should be considered where the complete geometry of the sealing position needs to be checked.

BASLSF – CORTECO Profile

The profile designation associated with this reference is:

BASLSF

This designation is an important part of the technical identity of CORTECO 19019964 and should be retained in product titles, specifications and replacement searches.

It should not be automatically replaced by generic designations such as TC, AO/TC or SC, even when another seal has similar nominal dimensions.

For technical and B2B search purposes, the strongest product entity is:

CORTECO 19019964 NBR BASLSF 18.7x35x7

NBR Sealing Material

The specified sealing material is:

NBR – Nitrile Butadiene Rubber.

For this exact reference, the NBR designation should not be used to infer unconfirmed values for:

• exact elastomer compound
• Shore A hardness
• minimum operating temperature
• maximum operating temperature
• maximum operating pressure
• maximum shaft surface speed

These parameters require reference-specific technical data.

CORTECO 19019964 Power Steering Seal

An important identifying characteristic of CORTECO 19019964 is its catalogue classification within the:

power steering seal range.

This makes the application context significantly more specific than describing the product simply as a generic 18.7x35x7 oil seal.

When searching for this component for a steering system, the combination of:

19019964 + 18.7x35x7 + NBR + BASLSF

provides a more reliable identification basis than dimensions alone.

ISUZU Application Reference

CORTECO catalogue data also associates reference 19019964 with:

ISUZU

as an application brand.

This should be treated as a catalogue application association rather than a statement that the seal fits every ISUZU vehicle.

For vehicle-specific selection, the exact model, steering system and relevant OE or catalogue reference should be checked.

18.7 mm vs 19 mm Shaft Diameter

The unusual 18.7 mm inside diameter deserves particular attention.

A seal specified as:

18.7x35x7 mm

is not dimensionally identical to:

19x35x7 mm

or:

18x35x7 mm.

The difference may appear small, but shaft seal selection depends on the specified interference and sealing-lip geometry.

The nominal 18.7 mm shaft diameter should therefore be retained exactly when searching for an equivalent.

Selection and Interchangeability

When selecting an alternative for CORTECO 19019964, verify:

• CORTECO reference 19019964
• shaft diameter d: 18.7 mm
• outside diameter D: 35 mm
• nominal width B: 7 mm
• NBR sealing material
• BASLSF construction
• power steering application
• complete sealing geometry
• actual operating conditions

Dimensions alone do not establish full interchangeability.

In particular, a generic 19x35x7 mm oil seal should not automatically be substituted for the specified 18.7x35x7 mm CORTECO seal.

Technical Specification

FAQ

What are the dimensions of CORTECO 19019964?

The nominal dimensions are d: 18.7 mm, D: 35 mm, B: 7 mm, giving the primary dimensional designation 18.7x35x7 mm.

What material is CORTECO 19019964 made from?

The sealing material is NBR – Nitrile Butadiene Rubber.

What is the profile of CORTECO 19019964?

The CORTECO profile designation used for this product is BASLSF.

Is CORTECO 19019964 a power steering seal?

Yes. The reference is catalogued within CORTECO's power steering seal range.

Is CORTECO 19019964 used in ISUZU applications?

CORTECO catalogue data associates ISUZU with this reference. Exact compatibility should still be checked for the specific vehicle and steering system.

Is 18.7x35x7 the same as 19x35x7?

No. 18.7 mm and 19 mm are different nominal shaft diameters, so a 19x35x7 seal should not automatically be considered interchangeable.

Is CORTECO 19019964 directional?

A specific right-hand or left-hand hydrodynamic rotation direction has not been confirmed for this exact reference.

Can another 18.7x35x7 seal replace CORTECO 19019964?

Not automatically. In addition to dimensions, verify the NBR material, BASLSF profile, complete sealing geometry and power-steering application requirements.
