CORTECO 19016647 ACM RHTC 52x70x8.5 mm

CORTECO 19016647 ACM RHTC 52x70x8.5 mm - Toyota Rotary Shaft Seal

CORTECO 19016647 ACM RHTC 52x70x8.5 mm is a radial rotary shaft seal designed for selected Toyota drivetrain applications. It is manufactured from ACM (polyacrylate rubber) and has a 52 mm inside diameter, 70 mm outside diameter and 8.5 mm width. CORTECO specifies the RHTC profile, right-hand twist and an additional dust lip. The product is also encountered as CORTECO 19016647B.

CORTECO 19016647 - Technical Data

What Does CORTECO 19016647 ACM RHTC Mean?

The complete designation identifies a specific CORTECO rotary shaft seal.

CORTECO - manufacturer and brand specialising, among other product groups, in sealing technology.

19016647 - CORTECO reference number for this specific product.

19016647B - reference also encountered in current parts catalogues and distribution channels.

82016647 - trade number associated with this product.

ACM - polyacrylate rubber used as the elastomer material.

RHTC - CORTECO profile designation assigned to this specific seal construction.

52x70x8.5 mm - nominal dimensions: 52 mm inside diameter, 70 mm outside diameter and 8.5 mm width.

The RHTC profile and right-hand twist are important technical identification characteristics. Another 52x70x8.5 mm oil seal should not automatically be considered interchangeable with CORTECO 19016647.

CORTECO 19016647 Dimensions

The nominal dimensions are:

52x70x8.5 mm

where:

52 mm - inside diameter

70 mm - outside diameter

8.5 mm - seal width

The inside diameter corresponds to the nominal diameter of the mating rotating component, while the outside diameter corresponds to the nominal housing bore.

Dimensions alone are not sufficient to establish interchangeability.

The ACM material, RHTC profile, directional sealing geometry, additional dust lip and OE reference should also be considered.

ACM - Polyacrylate Rubber

CORTECO specifies ACM, or polyacrylate rubber, for reference 19016647.

ACM is an elastomer used in technical rotary shaft sealing systems, including automotive drivetrain and transmission-related applications operating with compatible lubricants.

However, the general properties of ACM should not be treated as the exact operating specification of this individual CORTECO seal.

Actual suitability depends on the specific elastomer compound, operating medium, temperature, shaft surface speed and design of the complete sealing system.

For this reason, no unverified exact temperature, pressure or rotational speed limits are assigned to CORTECO 19016647.

CORTECO RHTC Profile

CORTECO identifies this seal with the RHTC profile.

The profile is an integral part of the technical specification and should be considered when identifying the product or selecting an alternative.

For CORTECO 19016647B, catalogue data also confirms a right-hand twist.

This means that another shaft seal with the same 52x70x8.5 mm dimensions but a different directional sealing geometry should not automatically be treated as an equivalent.

The individual letters in RHTC should not be decoded using another manufacturer's terminology. Seal profile nomenclature can be manufacturer-specific.

Right-Hand Twist

CORTECO 19016647B is specified with a right-hand twist.

Directional sealing features are designed to operate under defined shaft rotation conditions and form part of the functional geometry of the sealing lip.

This characteristic should therefore be checked when selecting a replacement.

A 52x70x8.5 mm seal with a different twist direction or a non-directional sealing design may have identical nominal dimensions but still be a technically different product.

Additional Dust Lip

CORTECO 19016647B is specified with an additional dust lip.

The auxiliary lip provides an additional barrier against external contamination reaching the primary sealing area.

This is particularly relevant in automotive drivetrain applications where the sealing position may be exposed to dust, dirt and other external contaminants.

A 52x70x8.5 mm shaft seal without an additional dust lip should not automatically be considered a complete technical equivalent of CORTECO 19016647.

Construction and Operating Principle

CORTECO 19016647 is a radial rotary shaft seal designed to operate between a rotating component and a stationary housing.

The primary sealing lip works against the mating surface and helps retain lubricant inside the protected assembly.

The additional dust lip helps reduce the ingress of contamination from the external side.

The RHTC profile also incorporates a defined directional characteristic associated with right-hand rotation.

Correct operation therefore depends on more than the basic 52x70x8.5 mm dimensions. Installation orientation, shaft condition, rotation direction, lubricant and material compatibility should also be considered.

CORTECO 19016647 - Toyota Application

The CORTECO dimensional catalogue associates 19016647 ACM RHTC 52x70x8.5 mm with Toyota applications.

Current parts catalogues classify the product in drivetrain applications, including differential and axle-related sealing positions.

CORTECO 19016647 should therefore not be treated simply as a universal industrial 52x70x8.5 mm oil seal. It is a specific automotive reference with a defined Toyota OE cross-reference.

For vehicle selection, the OE number and exact drivetrain configuration should be checked.

Toyota OE 9031152003

CORTECO 19016647B is associated with the OE reference:

TOYOTA 9031152003

The OE number provides an important identification point when comparing the CORTECO product with the original Toyota seal.

CORTECO 19016647 / 19016647B can therefore be searched using Toyota reference 9031152003.

Final compatibility should still be confirmed for the exact vehicle model, production year, axle configuration and installation position.

CORTECO 19016647 vs Other 52x70x8.5 mm Shaft Seals

The nominal dimensions 52x70x8.5 mm are not sufficient to establish complete interchangeability.

CORTECO 19016647 has the confirmed combination:

52x70x8.5 mm

ACM

RHTC

right-hand twist

additional dust lip

Toyota application

OE 9031152003

Another seal may share the same basic dimensions while using a different elastomer, sealing profile, lip geometry or intended application.

For this reason, dimensional matching alone should not be used as the only replacement criterion.

The safest identification method is to compare the complete CORTECO reference, OE number, dimensions, elastomer material, profile and directional sealing construction.

Cross-Reference Numbers

Cross-reference catalogues associate CORTECO 19016647B with references including:

AJUSA 15049600

PAYEN NJ645

Cross-reference numbers can assist with product identification, but they should not be treated as independent proof of complete technical interchangeability.

Before replacing the CORTECO product with another manufacturer's seal, compare the complete technical specification, construction and intended application.

Selection and Interchangeability

Before purchasing or replacing CORTECO 19016647 / 19016647B, verify:

• complete CORTECO reference,
• dimensions 52x70x8.5 mm,
• ACM elastomer material,
• RHTC profile,
• right-hand twist,
• additional dust lip,
• Toyota OE 9031152003,
• installation position,
• axle or differential configuration,
• required direction of operation,
• condition of the mating surface,
• operating lubricant,
• requirements of the specific application.

Identical dimensions do not automatically mean complete interchangeability.

A 52x70x8.5 mm seal manufactured from a different elastomer or featuring a different profile and directional geometry may be a technically different product.

Installation of CORTECO 19016647

Before installation, carefully clean the housing bore and the mating surface.

The sealing lip contact area should be free from corrosion, sharp edges, burrs and deep wear grooves that could damage the seal or cause leakage.

Install the seal squarely and evenly using an installation tool suitable for its diameter and construction.

Protect the primary sealing lip and additional dust lip against cutting, folding or deformation during assembly.

Because CORTECO 19016647B has a directional RHTC construction with right-hand twist, the required shaft rotation direction and correct installation orientation should also be verified before assembly.
