Heavy Duty Metal Face Seals

General Information

Heavy-Duty Metal Face Seals are sealing systems for heavy construction vehicles and agricultural equipment. The seals are found in the Final Drives, Sprockets and Track Rollers in tracked equipment and in Axles, Drive Trains and Wet Brakes in wheeled equipment. These Heavy-Duty Seals are also exclusively used in Tunnel Boring and Underground Mining Machinery.

MORCOR represents the world's premier engineering and manufacturing company of Heavy Duty Seals -- GOETZE. Goetze seal engineers developed the "O-Ring Style" seal over 40 years ago, and since that time it has become the preferred system for EXTREME APPLICATIONS. Goetze seals are the highest quality seals in the world today and Goetze manufactures more sizes of these seals than anyone else.

Sometimes referred to as Toric Seals, this sealing system is recognized as the preferred method for protecting bearings, gears and their lubricants from abrasive media and severe environments. The construction of the seal is conducive to simple and cost-effective designs. The face seal consists of two metallic seal rings which have the same geometric contour and are flexibly located in O-rings.The function of these O-rings, which act as springs, is to maintain axial sealing pressure, provide a static seal between the seal ring and housing bore, and transmit frictional torque. The seal is designed so that one of the two seal rings rotates while the other is stationary. It is superior to all other forms of radial or axial sealing owing to its small space requirement, simple construction and wear resistance. From tractors to trenchers, GOETZE seals are hard at work with OEM's all over the world.

Typical Applications

Mechanical Face Seal type 76.90H / 76.97H

• Seal for screw conveyor for abrasive materials
  Lubrication chamber sealed with radial lip seal; back surface facing lubricant to prevent pressure build-up in the sealing space.
  
• Seal for rigid axle of tractor
  

Mechanical Face Seal type 76.90H / 76.97H with Adapter Rings type 76.91

• Seal for tread roller of excavator
  
• Seal for transmission housing
  Designed with Adapter Rings type 76.91 for installation in cylindrical housing bores.
  

Mechanical Face Seal type 76.95

• Seal for cutting shaft of crop harvester
  
• Seal for screw conveyor for abrasive materials
  

Mechanical Face Seal special design type 76.93

• Seal for wheel bearing axle
  The inner tapered ring enables the housing contour to be machined directly on the shaft.
  
• Seal for steering drive axle
  Steering movements cause an axial displacement of the floating axle of about 5 mm. This movement is compensated by the double configuration of the seal.
