Seal washer for Twin Disc transmissions

The 201093 seal washer serves as a hybrid component within Twin Disc transmission systems. It is engineered to distribute the clamping load of fasteners while simultaneously providing a tight seal against the escape of lubricants or the ingress of external contaminants. By creating a barrier at bolted connections, it helps maintain the integrity of internal systems that operate under pressure or require protection from the environment.

This component is compatible with various Twin Disc transmissions, torque converters, and power control systems found in heavy machinery and marine applications. It consists of a metallic outer ring for structural support and an elastomeric insert designed to compress against mating surfaces to ensure a leak-proof connection. Proper installation is necessary to achieve the required compression without causing permanent deformation of the seal.

In mechanical assemblies, seal washers are utilized wherever a threaded fastener must also function as a fluid barrier. They are essential in gearboxes and hydraulic circuits to prevent the loss of oil or grease, which can lead to system contamination and internal component wear. Maintaining the integrity of these seals is a standard procedure during the service of power transmission equipment to ensure the continued operation of the machinery.
