This is Cassette seals (JOHN DEERE AL79951, RWDR CASSETTE-3 SEAL 53.2*78*13/14 NBR) consist of a Simmerring and optimized wear sleeve(either hard or soft untized). They are used to seal shafts in heavy construction and agricultural equipment that , for example, are exposed to high stresses. They also effectively protect engines, transmissions,differentials and axles against dirt,water and other enviromentaal influences. The latest developments in elastomers also make it possible to achieve optimal sealing without a spring. this reduces friction even at high temperatures.
 
A robust axle hub seal with multiplepoint exclusionary labyrinth built into a single housing, this seal is the ultimate at keeping the elements out and oil in while minimizing friction. The unique design provides outstanding contaminant exclusion at optimized surface speeds.
