Main Description

The Shaft Seal CORTECO 19033908 ACM RHSC 46x63x7,7 is a precision-engineered radial shaft seal designed for reliable sealing of rotating shafts in industrial and automotive powertrain applications. Known in the industry as a simmerring, this component provides effective prevention of lubricant leakage and ingress of contaminants in transmissions, transfer cases, and drive assemblies. It is widely referenced in aftermarket and OEM parts catalogs and commonly searched under terms such as “simmering 46x63x7,7” and “shaft seal for gearboxes.”

Constructed from high-performance ACM (acrylic rubber), the seal offers excellent resistance to mineral oils, automatic transmission fluids, and typical gear oils. The RHSC profile ensures stable contact with the shaft surface, maintaining effective sealing performance under continuous rotation and variable operating loads. This balanced seal face geometry minimizes wear and maintains long-term sealing integrity even in demanding environments where elevated temperatures and heavy usage are present. This shaft seal is frequently specified as a direct replacement for OEM part numbers from major vehicle manufacturers including BMW 24231219547, Mazda BV3519241 & BV1119241, and Nissan 3737551X03, 3137551X03, 3137551X00 — making it a sought-after part for automotive repair and industrial drivetrain service. It is suitable for both professional workshops and OEM assembly lines requiring consistent fitment and reliable sealing performance across popular models.

With its optimized elastomer compound and precision molded lip design, the CORTECO 19033908 shaft seal supports efficient retention of lubrication and protects against external particulate ingress, extending component life and reducing downtime. It is compatible with standard installation tools used for radial shaft seals, facilitating quick and secure mounting into housings or bearing covers.
