CORTECO 19015083 ACM RHTC 35x50x8 mm Oil Seal - Simmerring

1. Technical Specification

The complete designation CORTECO 19015083 ACM RHTC 35x50x8 mm should be retained when identifying or procuring this sealing component.

2. RHTC Radial Shaft Seal Construction

CORTECO 19015083 is a radial shaft seal designed to restrict lubricant leakage along a rotating shaft.

The RHTC construction combines primary oil retention with additional protection against external contamination.

Main Functional Components

Primary sealing lip

The primary lip contacts the rotating shaft surface and helps retain lubricating oil within the mechanical assembly.

Additional dust exclusion lip

The secondary lip helps prevent dust and small external contaminants from reaching the primary sealing interface.

Right-hand hydrodynamic twist structures

These structures are designed to influence lubricant movement at the sealing interface when the shaft rotates in the specified direction.

ACM elastomer

Polyacrylate rubber provides elastic sealing properties and resistance to many engine oils.

Seal body

The body allows installation in a housing with a nominal bore diameter of 50 mm.

The exact reinforcement materials and garter spring arrangement should be confirmed using the manufacturer's technical drawing.

3. What Does RHTC Mean?

RHTC is the construction profile designation associated with this CORTECO oil seal.

For CORTECO 19015083, catalogue information identifies a right-hand hydrodynamic twist arrangement and an additional dust exclusion lip.

The RHTC designation should be retained when selecting a replacement.

It should not automatically be considered interchangeable with TC, BASL, HTC or LHTC profiles.

The hydrodynamic twist direction is particularly important because it can influence sealing performance at a specific shaft rotation direction.

4. ACM Material - Technical Properties

ACM (Acrylic Rubber), also known as polyacrylate rubber, is a synthetic elastomer used in technical sealing applications, particularly in systems lubricated with oil.

It generally provides good resistance to many engine oils and elevated operating temperatures.

Typical ACM Properties

• Good resistance to many engine oils.

• Good resistance to thermal ageing.

• Good resistance to ozone.

• Suitable for selected dynamic shaft sealing applications.

• Limited resistance to fuels and certain organic solvents.

• Generally less favourable low-temperature flexibility than some NBR compounds.

The actual performance of a specific ACM seal depends on compound formulation and operating conditions.

5. Chemical Resistance of ACM

This table describes the general ACM material family and does not represent confirmed chemical resistance testing for CORTECO 19015083.

6. Temperature Resistance

For many ACM compounds, an approximate operating temperature range of -20°C to +150°C is commonly referenced.

Specialized formulations may have different temperature limits.

This range is general material guidance and is not a confirmed operating specification for CORTECO 19015083.

During product selection, the oil temperature, shaft rotational speed and frictional heating at the sealing lip must be considered.

7. Dimensions 35x50x8 mm Explained

These dimensions are nominal.

Correct selection also depends on shaft and housing tolerances, surface finish and the specified RHTC construction profile.

Matching dimensions alone do not establish interchangeability with another oil seal.

8. Right-Hand Hydrodynamic Twist

CORTECO 19015083 features a right-hand hydrodynamic twist configuration, identified in catalogue descriptions as Right-hand Twist.

These structures are intended to influence the thin lubricant film at the shaft contact interface.

Under the appropriate shaft rotation conditions, hydrodynamic features can help direct lubricant toward the oil side of the seal.

A right-hand twist design should not automatically be considered suitable for every shaft rotation direction.

The actual rotation direction must be checked according to the manufacturer's viewing and identification convention.

If the shaft rotates in an incompatible direction, the hydrodynamic structures may not provide their intended sealing effect.

9. Application - Camshaft Oil Seal

CORTECO 19015083B is catalogued for engine applications, including camshaft sealing arrangements.

In this application, the seal helps prevent engine oil leakage where a rotating camshaft passes through the engine housing.

Catalogue references include selected Mitsubishi applications and original equipment references associated with Lombardini and SAME.

Compatibility with a specific engine or machine must be established using the original part number and technical documentation.

10. OE References - Lombardini, Mitsubishi and SAME

The SAME reference may also appear in the shortened form 1026592.

These OE numbers are associated with CORTECO 19015083B in replacement-part catalogues.

They should be checked against the exact engine or mechanical assembly before installation.

Additional Cross-References

Cross-reference numbers support product identification but do not independently guarantee compatibility with every application.

11. Comparison with Other 35x50x8 mm Oil Seals

Radial shaft oil seals with identical nominal dimensions may use different elastomers, lip geometries or hydrodynamic profiles.

The listed references may differ in sealing material, construction or lip profile despite sharing nominal dimensions.

CORTECO 19015083 ACM RHTC should not automatically be replaced with a standard TC 35x50x8 mm oil seal.

The original equipment requirements must be verified before confirming interchangeability.

12. CORTECO 19015083 Selection Criteria

Before selecting this oil seal, verify the following parameters:

Manufacturer reference

CORTECO 19015083 or 19015083B.

Sealing material

ACM polyacrylate rubber.

Construction profile

RHTC.

Shaft diameter

35 mm nominal.

Housing bore

50 mm nominal.

Seal width

8 mm nominal.

Hydrodynamic twist direction

Right-hand twist.

Operating medium

The lubricant and its additives must be compatible with ACM.

Operating conditions

Temperature, shaft speed and pressure must remain within the permissible limits of the exact seal.

Mating surfaces

The shaft and housing surfaces must meet the installation requirements.

Original equipment compatibility

The OE reference must correspond to the specific engine or mechanical assembly.

Particular attention should be given to shaft rotation direction because the RHTC profile incorporates directional hydrodynamic structures.

13. Installation and Maintenance Recommendations

Before installation, thoroughly clean the shaft and housing bore.

The shaft contact surface should be free from burrs, deep scratches and excessive wear.

Recommended installation practices include:

• Verifying the complete manufacturer reference and RHTC profile.

• Confirming the shaft rotation direction.

• Protecting the sealing lip from sharp edges.

• Using suitable installation tools.

• Maintaining correct alignment during insertion.

• Preparing the sealing surfaces according to the engine manufacturer's instructions.

• Checking for leakage after commissioning.

Incorrect installation can damage the sealing lip, cause lubricant leakage or accelerate shaft wear.
