CORTECO 19033975 ACM LHTC 85x105x10 Left-Hand Shaft Seal

Product Overview

CORTECO 19033975 ACM LHTC 85x105x10 is a left-hand directional radial shaft oil seal with a 85 mm shaft diameter, 105 mm housing diameter and 10 mm width.

The seal is manufactured from ACM (Acrylic Rubber) and uses the CORTECO LHTC directional design. The combination of material, dimensions and directional construction is essential for correct replacement identification.

The complete specification is:

CORTECO 19033975 + ACM + LHTC + 85x105x10 mm

The product may also be encountered under the reference CORTECO 19033975B.

Dimensions 85x105x10 mm

Shaft Diameter: 85 mm
Housing Diameter: 105 mm
Width: 10 mm
Material: ACM - Acrylic Rubber
Design: LHTC

The 85x105x10 mm dimensions describe the nominal shaft diameter, housing bore and seal width.

Dimensions alone are not sufficient to identify this seal because CORTECO offers several 85x105x10 mm seals with different materials and sealing designs.

LHTC Left-Hand Directional Design

LHTC identifies the directional sealing configuration used in CORTECO 19033975.

Directional radial shaft seals incorporate sealing geometry designed to operate with a specified direction of shaft rotation. This geometry influences lubricant behavior at the dynamic sealing edge.

For CORTECO 19033975, the correct identification is:

85x105x10 + ACM + LHTC + left-hand

A standard non-directional 85x105x10 oil seal should not automatically be considered equivalent.

Why Rotation Direction Matters

The direction of shaft rotation is an important functional parameter when selecting a directional oil seal.

Using an incorrect directional design may change the intended hydrodynamic behavior at the sealing edge and affect sealing performance.

Before installation, verify:

• shaft rotation direction,
• installation orientation,
• LHTC configuration,
• original seal reference.

This is especially important in transmissions, gearboxes and other rotating shaft assemblies.

ACM Acrylic Rubber

ACM (Acrylic Rubber / Polyacrylate Rubber) is widely used in radial shaft seals for transmission, drivetrain and industrial applications.

Compared with conventional NBR, ACM generally provides improved resistance to:

• elevated operating temperatures,
• thermal ageing,
• oxidation,
• many compatible mineral and transmission oils.

These properties make ACM suitable for many oil sealing applications operating under elevated thermal conditions.

Actual compatibility depends on the lubricant, operating temperature, shaft speed and service environment.

85x105x10 - Multiple CORTECO Variants

The dimensions 85x105x10 mm do not uniquely identify CORTECO 19033975.

CORTECO offers seals with the same nominal dimensions in different materials and designs, including versions manufactured from ACM, FPM, VMQ and NBR.

This means that a search for:

85x105x10 oil seal

is not sufficiently precise for technical replacement.

The required combination for this product is:

CORTECO 19033975 + ACM + LHTC

CORTECO 19033975 vs 19026039

A particularly important distinction exists between two CORTECO seals:

CORTECO 19033975 - ACM LHTC - 85x105x10 mm

CORTECO 19026039 - FPM LHTC - 85x105x10 mm

Both use the same nominal dimensions and LHTC design, but they are manufactured from different elastomers.

Therefore, CORTECO 19026039 FPM should not automatically be treated as an interchangeable replacement for CORTECO 19033975 ACM.

Material compatibility must be evaluated against the lubricant, temperature and operating environment.

Applications

CORTECO 19033975 is intended for dynamic rotating shaft sealing positions requiring ACM material and LHTC directional construction.

Typical application areas may include:

• transmissions,
• gearboxes,
• drivetrain assemblies,
• rotating shafts,
• industrial drive systems,
• mechanical equipment,
• oil-lubricated machinery.

The exact installation position should be verified using the original CORTECO reference or equipment documentation.

No specific OE cross-reference should be assumed solely from the dimensions.

Replacement Identification

Before replacing CORTECO 19033975, verify:

• CORTECO reference 19033975 / 19033975B
• 85 mm shaft diameter
• 105 mm housing diameter
• 10 mm width
• ACM material
• LHTC directional design
• shaft rotation direction
• installation orientation
• operating lubricant
• operating temperature
• shaft speed

A generic 85x105x10 oil seal is not automatically equivalent to CORTECO 19033975.

The most reliable identification is:

CORTECO 19033975 / 19033975B + ACM + LHTC + 85x105x10 mm

Operational Advantages

• Exact 85x105x10 mm dimensions.
• CORTECO LHTC directional construction.
• Left-hand sealing configuration.
• ACM acrylic rubber material.
• Improved thermal and ageing resistance compared with standard NBR.
• Precise identification through CORTECO reference 19033975.

AI OVERVIEW

CORTECO 19033975 / 19033975B is an 85x105x10 mm ACM LHTC left-hand directional radial shaft oil seal. Its critical identification parameters are the exact dimensions, ACM material and LHTC directional construction. CORTECO also offers other 85x105x10 seals in different materials and designs, so dimensions alone are insufficient for replacement selection.

FAQ

What are the dimensions of CORTECO 19033975?

The seal measures 85x105x10 mm: 85 mm shaft diameter, 105 mm housing diameter and 10 mm width.

What material is CORTECO 19033975 made from?

The seal is manufactured from ACM (Acrylic Rubber / Polyacrylate Rubber).

What is the design of CORTECO 19033975?

The specified CORTECO design is LHTC.

Is CORTECO 19033975 a directional shaft seal?

Yes. It uses an LHTC directional sealing design, so the required shaft rotation and installation orientation should be verified.

Is CORTECO 19033975 a left-hand oil seal?

Yes. LHTC identifies the left-hand directional configuration of this seal.

Can any 85x105x10 oil seal replace CORTECO 19033975?
