Integrated combination of hydraulic swing motor body, internal friction assemblies and multi-stage planetary swing reduction gearbox, fully consistent with OEM No.4199024 / 4224917 / 9097684 for Hitachi EX100WD; no cutting, grinding or separate component matching required during on-site replacement.
Quenched alloy steel gear teeth resist frequent impact loads in urban construction sites and small quarries, output stable slewing torque and effectively prevent gear tooth fracture under continuous medium-load operation.
Genuine OEM original, brand new aftermarket and remanufactured overhauled versions are permanently stocked to satisfy differentiated budget demands of wholesalers and professional maintenance workshops.
Internal buffer design relieves sudden hydraulic pressure impact during swing start and stop, suppresses whole-machine vibration, reduces abrasion of internal core parts and extends the full service life of the entire slewing drive system.
FAQ
Q:What core operation standards for installing EX100WD swing reduction drive device?
A:Thoroughly clear all metal debris and impurities on slewing bearing mounting surface before assembly; fasten all flange bolts evenly following diagonal torque sequence; fill the reduction gearbox with dedicated heavy-load gear oil after installation and complete no-load rotation test before formal construction work.
Q:What information should be submitted to verify compatibility before bulk purchase?
A:Provide excavator model Hitachi EX100WD and cross OEM part numbers 4199024 / 4224917 / 9097684; we cross-check full assembly dimensional drawings to avoid mismatched whole units and unnecessary inventory losses.
Q:How does this swing reduction gearbox assembly perform in cold mountain construction sites and high-dust hot quarries?
A:Low-temperature adaptive alloy and high-temperature resistant sealing components maintain stable working performance within -22℃ ~ +58℃; fully sealed gearbox structure blocks mineral dust invasion and reduces internal abrasive wear.
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
