Duo Cone Seals
Floating Seals
Mechanical Face Seals

Description

Duo-cone seals (also known as mechanical face seals) are mechanical seals used to keep the oil within your final drive motor, as well as keep damaging contamination outside. These seals are comprised of two metal faces (which is why they are sometimes called floating face seals) and two flexible toric rings that forces those faces together so that they form a tight seal. The toric rings are made from a rubber or elastomeric material and get their name from their torus shape.

The floating face seal is a vital part of your travel motor or final drive, whether its on a John Deere skid steer or an ASV compact track loader. It rests against the hub, holding in the gear oil on the planetary side and preventing contaminants from getting in where they can damage bearings and gear. If this seal begins to leak, your travel drive motor will suffer damage.

The floating face seal has been designed to survive in some of the most extreme conditions encountered with construction equipment and earth-moving equipment.  However, keep in mind that floating face seals have a limited life span and are supposed to be replaced during the life of your equipment, whether its an ASV drive motor or a CAT hydraulic motor. That life span can be extended by carefully cleaning out debris from around the face seal using a hose or pressure washer.  That same life span can be drastically reduced by allowing abrasive contaminants to get packed in tightly around the face seal by not cleaning your machine and, if applicable, the undercarriage.

1 Using specialized tools installation: Seal Solutions Australia also offer custom made Nylon Installation Tools to suit any size Duo Cone or Floating Seal. The pressure will apply to the O-ring directly. As shown, the special tool is mounted between the metal floating ring and the rubber ring: toward the seat hole, the rubber ring is evenly pressed into the hole.

2 Other installation methods: One auxiliary O-ring is fixed between the conical ring surface of the floating oil seal and sealing O-ring (as shown). The ring of the floating oil seal is applied uniformly by pressure and the auxiliary O-ring braces the sealing O-ring to ensure the other correct mounting positions.
