Rotary Shaft Seal CORTECO 19035393 - Oil Seal 26.90x42x6 RHTC

Applications and Operational Use

The CORTECO® 19035393 rotary shaft seal is engineered for sealing rotating shafts in automotive transmission systems, particularly in Suzuki manual gearboxes. Its primary function is to retain lubricating oil inside the gearbox while preventing dust, dirt, and moisture from entering the sealing interface. Designed with a right-hand twist (RHTC) sealing lip, this oil seal efficiently channels oil back toward the internal lubrication zone during shaft rotation, improving long-term sealing performance and reducing fluid leakage.

Advantages and Material Properties

This shaft seal is manufactured from ACM (Acrylic Rubber), a material chosen for its strong resistance to gear oil, friction, and elevated operating temperatures. ACM ensures durability in continuous mechanical operation, making it suitable for demanding automotive environments. The seal structure provides stable performance in high-rotation applications, while the precision-ground sealing lip reduces wear on both the shaft and the seal itself. This results in extended service life and enhanced reliability for transmission components.

Main Description

The CORTECO 19035393 rotary shaft seal is a high-performance oil seal designed to provide reliable sealing for rotating shafts in Suzuki manual transmissions. Its optimized RHTC lip geometry improves oil retention, maintaining the optimal lubrication film while preventing leakage and contamination. This technical seal ensures stable operation under continuous mechanical load and temperature variations commonly found in gearbox systems.

Constructed from ACM rubber, the seal offers excellent resistance to hot gear oils and oxidation, making it suitable for extended service intervals. The precision sealing edge ensures smooth contact with the shaft surface, reducing friction, wear, and heat buildup. This contributes directly to gearbox efficiency, lower maintenance requirements, and reduced risk of premature component failure.

The CORTECO 19035393 oil seal is widely used in automotive repair workshops, gearbox rebuild services, OEM maintenance programs, and industrial transmission applications where compact and reliable shaft sealing is required.

FAQ

What is the purpose of a rotary shaft seal?
It prevents lubricating oil from escaping the housing while blocking contaminants from entering the system.

How is a right-hand twist lip different from a standard seal?
The RHTC lip design actively directs oil back toward the bearing or gearbox interior during shaft rotation, increasing sealing efficiency.

What is ACM rubber used for?
ACM is resistant to hot gear oils and high temperatures, making it ideal for automotive transmission and engine sealing environments.

How do I confirm the correct seal size?
Match the shaft diameter, housing bore, and seal thickness to the exact dimensions specified: 26.90x42x6 mm.
