Twin Disc
Oil seal for Twin Disc transmissions
This oil seal is designed for use in Twin Disc transmissions to retain lubricant and prevent the ingress of external contaminants. It ensures that internal components remain protected from dirt and moisture during operation.

The oil seal M136A acts as a barrier within Twin Disc transmission systems. Its primary function is to contain the lubricating oil within the housing, ensuring that gears, bearings, and rotating shafts remain properly lubricated. Simultaneously, the seal prevents external contaminants such as dust, dirt, and moisture from entering the transmission housing, which protects internal surfaces from abrasive wear and corrosion. Proper sealing is necessary for the mechanical integrity of the transmission assembly.
This component is engineered for integration into various Twin Disc transmission models. It is designed to maintain a secure fit against the shaft and housing to provide an effective barrier under typical operating temperatures and rotational speeds. Regular inspection of this seal is recommended to identify signs of leakage or material degradation, as maintaining an airtight and fluid-tight seal is necessary for the continued operation of the transmission system.
Oil seals function by providing a flexible interface between a stationary housing and a rotating shaft. By maintaining this contact, the seal manages fluid pressure and prevents leakage, which is essential for the lubrication cycles of heavy machinery transmissions.
