Shaft Seals-Trends and Developments for Off Highway Heavy Equipment Applications

The paper will review existing seals used in off-highway heavy equipment, both radial lip seal applications and face type seal applications in general use on track vehicles. With the trend towards improved reliability and durability, together with the never ending quest for quality and product improvements, the paper will discuss a number of seal development programs which will result in products that meet the new and projected future requirements for seals from the off-highway heavy equipment manufacturers.
