CORTECO 19036367 Rotary Shaft Seal 44.1x70x6.7/8.1 FPM HTC5Y

The CORTECO 19036367 rotary shaft seal (oil seal 44.1x70x6.7/8.1 mm, FPM HTC5Y) is a precision-engineered sealing element designed for transmissions, gearboxes, and drive units. Manufactured from fluoroelastomer (FPM/FKM), it provides outstanding resistance to heat, oil, and transmission fluids, ensuring long-term sealing reliability in demanding industrial and automotive applications.

This oil seal is frequently used as an OEM equivalent for BMW part number 24121423529, typically in automatic transmission housings and drive assemblies where tight tolerance and chemical resistance are critical. The dual-height profile (6.7 / 8.1 mm) allows flexible integration within bearing housings and bearing units, maintaining the integrity of internal lubrication systems and protecting components such as ball bearings from contamination.

With its advanced HTC5Y sealing profile, this CORTECO oil seal guarantees minimal friction, stable performance under high rotational speeds, and consistent sealing even under pressure differentials. Its precision-molded outer surface ensures firm retention in the housing bore and excellent resistance to vibration or misalignment during operation.

Application and Compatibility

• Designed for automatic and manual gearboxes, differentials, and drive shafts.

• Commonly used in BMW vehicles as replacement for OEM 24121423529.

• Suitable for bearing units and bearing housings that operate under heat and oil exposure.

• Applicable in industrial transmission systems, pumps, and drive assemblies requiring tight radial sealing.

• Compatible with lubricating oils, ATF, and synthetic fluids.

Construction, Material and Technical Data

• Material: FPM (FKM - fluoroelastomer) - resistant to oil, fuels, and high-temperature environments.

• Design type: HTC5Y - high-temperature configuration with precision sealing lip.

• Dimensions: 44.1 mm (ID) x 70 mm (OD) x 6.7 / 8.1 mm (width).

• Operating temperature range: −25 °C to +200 °C (intermittently higher).

• Reinforcement: Metal-reinforced outer shell for dimensional stability.

• Performance: High sealing efficiency, reduced friction, and extended service life.

• Durability: Exceptional wear resistance and chemical stability under long-term exposure to lubricants.

This seal maintains high endurance in dynamic environments, preventing leakage and extending the operational life of transmission bearings and gears.

Installation and Bearing Unit Integration

For optimal installation, press the seal evenly into the housing without deformation. Lubricate the sealing lip and shaft surface before assembly to minimize friction during start-up.

When integrated with a bearing housing or ball bearing unit, the CORTECO 19036367 provides a secure barrier between the lubricated internal environment and external contaminants. Its low-friction lip design protects rolling elements from oil loss and ingress of dirt or moisture, enhancing bearing longevity and reducing maintenance intervals.

Regular inspections of sealing surfaces and proper shaft finish are recommended to sustain maximum sealing efficiency and prevent premature wear.
