A Circular Seal is used in final drives and is typically known as a radial shaft seal or lip seal. It is a circular elastomeric element that is held in place against the drive shaft by a rigid outer housing. The seal arises from the frictional contact between the lip and the shaft, which is often reinforced by a spring.

Attributes:
● Machined precisely to the correct dimensions and tolerances to give improved durability
● Provides excellent resistance against corrosion, wear, and tear

Applications:
A Circular Seal is used to seal the clearance between the mating parts in the final drive, this is mostly used in CAT.
