CORTECO 19016638 ACM RHTC 35x49x6 mm - Toyota Rotary Shaft Seal

CORTECO 19016638 ACM RHTC 35x49x6 mm is a radial rotary shaft seal used in selected automotive applications, particularly Toyota engine applications. It is manufactured from ACM (polyacrylate rubber) and has a 35 mm inside diameter, 49 mm outside diameter and 6 mm width. CORTECO specifies the RHTC profile, right-hand twist and an additional dust lip. The product is also encountered as CORTECO 19016638B.

CORTECO 19016638 - Technical Data

What Does CORTECO 19016638 ACM RHTC Mean?

The complete designation identifies a specific CORTECO rotary shaft seal.

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

19016638 - CORTECO reference number for this specific product.

19016638B - reference also encountered in current parts catalogues and distribution channels.

82016638 - trade number associated with this product.

ACM - polyacrylate rubber used as the elastomer material.

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

35x49x6 mm - nominal dimensions: 35 mm inside diameter, 49 mm outside diameter and 6 mm width.

The complete combination of dimensions, material, profile and construction should be considered when identifying the product. Another 35x49x6 mm oil seal should not automatically be considered interchangeable with CORTECO 19016638.

CORTECO 19016638 Dimensions

The nominal dimensions are:

35x49x6 mm

where:

35 mm - inside diameter

49 mm - outside diameter

6 mm - seal width

The inside diameter corresponds to the nominal dimension 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, dust lip and OE application should also be checked.

ACM - Polyacrylate Rubber

CORTECO specifies ACM, or polyacrylate rubber, for reference 19016638.

ACM is an elastomer used in technical rotary shaft sealing systems, particularly in automotive applications operating with compatible oils and 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 19016638.

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 19016638B, catalogue data also confirms a right-hand twist.

Two seals with identical 35x49x6 mm dimensions can therefore have different functional constructions.

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

Right-Hand Twist

CORTECO 19016638B is specified with a right-hand twist.

Directional sealing features are associated with defined rotational conditions of the mating shaft.

This characteristic is important when selecting a replacement seal.

A 35x49x6 mm seal with a different twist direction or without directional sealing geometry may have identical basic dimensions but may not be technically equivalent to CORTECO 19016638.

Additional Dust Lip

CORTECO 19016638B is specified with an additional dust lip.

The auxiliary lip forms an additional barrier between the primary sealing area and the external environment.

It helps reduce the ingress of dust, dirt and other contaminants toward the primary sealing lip.

This is another important construction feature to consider when comparing CORTECO 19016638 with other 35x49x6 mm shaft seals.

Construction and Operating Principle

CORTECO 19016638 is a radial rotary shaft seal designed to operate between a rotating component and a stationary housing.

The primary sealing lip works against the shaft surface and helps retain lubricant within the protected assembly.

The additional dust lip provides secondary protection against contamination from the external side.

For CORTECO 19016638, the directional characteristics of the RHTC profile are also important.

Correct operation therefore depends not only on the 35x49x6 mm dimensions but also on installation orientation, direction of rotation, condition of the mating surface and compatibility of the ACM material with the operating conditions.

CORTECO 19016638 - Front-End Application

Catalogue data for CORTECO 19016638B specifies a front-end installation position.

Depending on the specific engine application, the product is catalogued as a camshaft seal or shaft seal.

The installation position should not be determined from dimensions alone.

For vehicle applications, the OE number, engine version and exact installation position should always be checked.

CORTECO 19016638 - Toyota Applications

CORTECO 19016638B is widely catalogued for selected Toyota applications.

Depending on the specific vehicle and engine, the product is used in shaft or camshaft sealing positions at the front end of the engine.

A vehicle family name alone does not confirm compatibility. Different engines, production years and configurations can use different shaft seals.

Final selection should therefore be based on the OE reference and exact vehicle or engine specification.

CORTECO 19016638 vs Other 35x49x6 mm Shaft Seals

The nominal dimensions 35x49x6 mm are not sufficient to establish complete interchangeability.

CORTECO 19016638 has the specific combination:

35x49x6 mm

ACM

RHTC

right-hand twist

additional dust lip

front-end application

defined OE references

Other 35x49x6 mm shaft seals may use different elastomer materials, profiles or sealing geometries.

For this reason, dimensions should never be the only replacement criterion.
