This pair of floating seals is essential for maintaining lubrication and preventing contamination within the final drive or slew ring assemblies of excavators. They create a dynamic seal between rotating and stationary components, ensuring the integrity of the bearing environment. Unlike worn seals that allow dirt ingress and lubricant escape, these seals provide robust protection and longevity. Operators may notice increased noise from the drive or slew system, premature bearing wear, or visible leakage of grease or oil when these seals fail.
Always verify with serial number before ordering.

Cross-reference part number with serial number before ordering to confirm fitment. Keep original parts until new ones are confirmed correct. Record part numbers replaced for future reference.
Always consult the OEM service manual for model-specific torque values and procedures. WhatsApp our technical team if you need fitment guidance.
The first sign of failing floating seals is often an audible increase in noise, such as grinding or whining, from the final drive or slew ring. This is typically followed by visible leakage of lubricant from the seal area, indicating a loss of sealing integrity. If left unaddressed, the ingress of contaminants will rapidly degrade the bearings, leading to premature and costly component failure.
Carefully clean the seal grooves and mating surfaces before installing the new seals to ensure a proper fit. Ensure the seal faces are lubricated and do not rotate the component until the seals are properly seated.
Inspect the bearing surfaces and the mating seal faces for any signs of scoring or damage when replacing floating seals.
