P&H 4100XPB Rebuild with Wearite bushes
ZEMEK Engineering has recently installed new Wearite bushes on a client's P&H4100 Dipper door. Wearite's demonstrated benefits: Improved safety - Dry ice use eliminates liquid nitrogen handling risk. - Safer handling with less than 3kg Wearite parts vs 20kg OEM metal parts. Reduced Cost - Two large bushes fitted under 30 minutes. - No grease required in operation. - No line bore required when replacing Wearite bushes.   See the simple installation ste...

FAQ - Time lost due to lubrication failure in excavators
  A. Polymer bushes such as Wearite can replace lubricated steel bushes in many parts of the excavator mechanism.  These materials are rated to the duty of heavy mining applications and can operate without lubrication.  Wearite users have been able to reduce the number of vulnerable lubrication lines and thus reduce downtime associated with failures in these lines.  Experience in excavators in the 300 tonne + class has shown a trouble-free life over.  Savings are ...
