CORTECO 19016922 ACM RHTC 48x70x12 mm Simmerring Rotary Shaft Seal

CORTECO 19016922 ACM RHTC 48x70x12 mm Simmerring Rotary Shaft Seal

CORTECO 19016922 ACM RHTC 48x70x12 mm is a radial rotary shaft seal manufactured from ACM elastomer. It has a nominal shaft diameter of 48 mm, outside diameter of 70 mm and width of 12 mm. CORTECO identifies this specific seal with the RHTC profile. It is catalogued for MAZDA applications and is used as a crankshaft seal.

CORTECO 19016922 - Technical Data

What Does CORTECO 19016922 ACM RHTC Mean?

The complete designation identifies the specific CORTECO shaft seal.

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

19016922 - CORTECO product reference for this specific seal.

19016922B - reference also encountered in current parts catalogues and distribution channels for this product.

ACM - polyacrylate rubber, the elastomer material specified for the sealing element.

RHTC - CORTECO profile designation for this particular seal design.

48x70x12 mm - nominal dimensions: 48 mm inside diameter, 70 mm outside diameter and 12 mm width.

CORTECO 19016922 Dimensions

The nominal dimensions are:

48x70x12 mm

where:

48 mm - nominal inside diameter / shaft diameter

70 mm - nominal outside diameter

12 mm - nominal seal width

All three dimensions must be considered when identifying a replacement. A matching 48 mm shaft diameter alone does not confirm interchangeability.

ACM - Polyacrylate Rubber

CORTECO specifies ACM for reference 19016922.

ACM is a polyacrylate elastomer used in technical sealing applications. It is particularly associated with applications requiring resistance to oils and elevated operating temperatures.

ACM is therefore encountered in various automotive, engine and transmission sealing systems.

However, a precise maximum operating temperature should not be assigned to CORTECO 19016922 solely from the general properties of ACM. The permissible temperature of a specific shaft seal depends on the actual elastomer compound, operating medium, lip design, shaft speed and operating conditions.

RHTC Profile

CORTECO identifies reference 19016922 with the profile designation RHTC.

The RHTC profile is an important part of the technical identification of this specific seal. A replacement should therefore not be selected solely because it has the same 48x70x12 mm dimensions.

Another 48x70x12 mm rotary shaft seal may use a different elastomer, sealing lip geometry, profile or directional sealing structure.

The complete design must be considered when evaluating interchangeability.

Right-Hand Twist

CORTECO 19016922 / 19016922B is listed with a right-hand twist.

This is a technically important characteristic of the sealing lip.

A directional hydrodynamic structure is associated with the direction of shaft rotation and is designed to support the return of the sealed medium toward the oil side during operation.

For this reason, a directional shaft seal should not automatically be replaced with a seal having the opposite twist direction or a different lip structure merely because the dimensions are also 48x70x12 mm.

Construction and Operating Principle

CORTECO 19016922 is a radial rotary shaft seal designed to seal between a rotating shaft and a stationary housing.

The 48 mm inside diameter corresponds to the nominal shaft diameter, while the 70 mm outside diameter corresponds to the seal housing bore.

During operation, the sealing lip maintains controlled contact with the rotating shaft surface. Its purpose is to retain the operating medium on the required side of the sealing point and limit leakage along the shaft.

The RHTC profile and right-hand directional characteristic are therefore important elements of the design of this specific CORTECO seal.

CORTECO 19016922 vs Other 48x70x12 mm Shaft Seals

The dimensions 48x70x12 mm alone do not uniquely identify a shaft seal.

Different seals can share the same nominal dimensions while differing in:

• elastomer material,
• sealing lip profile,
• directional structure,
• auxiliary sealing features,
• intended operating conditions,
• application.

For CORTECO 19016922, the ACM material, RHTC profile and right-hand twist should therefore be considered together with the 48x70x12 mm dimensions.

Identical dimensions do not automatically mean complete technical interchangeability.

Application of CORTECO 19016922

CORTECO catalogues reference 19016922 ACM RHTC 48x70x12 mm for MAZDA applications.

Parts catalogues identify this reference as a crankshaft seal installed at the timing end.

This means CORTECO 19016922 is not simply a generic 48x70x12 mm oil seal. It has a defined automotive application and a specific sealing design.

For installation in a particular vehicle, compatibility should be confirmed using the vehicle model, engine version, production year and relevant OE reference. Dimensions alone are not sufficient to confirm vehicle fitment.

Confirmed Cross-References

References encountered in parts catalogues for comparison and identification include:

CORTECO 19016922

CORTECO 19016922B

AJUSA 15024200

PAYEN NJ042

Cross-reference numbers are useful for product identification, but final interchangeability should be confirmed for the specific vehicle, engine and sealing position before installation.

Selection and Interchangeability

Before replacing CORTECO 19016922 with another shaft seal, verify:

• complete manufacturer reference,
• 48 mm inside diameter,
• 70 mm outside diameter,
• 12 mm width,
• ACM elastomer,
• RHTC profile,
• sealing lip construction,
• twist direction,
• shaft surface condition,
• operating medium,
• operating temperature,
• shaft speed,
• exact application requirements.

Identical 48x70x12 mm dimensions do not automatically mean complete interchangeability.

This is particularly important for directional rotary shaft seals, where the sealing lip geometry is designed with a specific direction of shaft rotation in mind.

Installation of CORTECO 19016922

Before installation, clean the housing bore and the shaft contact surface carefully.

The shaft surface in the sealing lip contact area should be free from corrosion, deep scratches, sharp edges and other damage that could cause premature wear or leakage.

The seal should be installed evenly using an appropriate installation tool acting on the correct face of the seal. Avoid deforming the seal body or damaging the sealing lip.

The correct installation orientation and directional characteristic of the RHTC design should be confirmed before fitting.

For crankshaft sealing applications, the condition of the shaft contact surface is particularly important. A wear groove left by the previous seal can cause leakage even after a new seal has been installed.
