Integrated combination of M2X210 hydraulic swing motor body, internal friction components and multi-stage planetary swing reduction gearbox, no cutting, grinding or separate component matching required during on-site replacement.
Quenched alloy steel gear teeth withstand severe impact loads in open-pit mines and quarries, output stable high slewing torque and effectively avoid gear tooth fracture under continuous full-load mining working conditions.
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 sharp hydraulic pressure impact during swing start and stop, suppresses whole-machine vibration, slows abrasion of internal core parts and extends the overall service life of the entire slewing drive system.
FAQ
Q:What core operation standards for installing EX270LC M2X210 swing drive assembly?
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 mining construction work.
Q:What information should be submitted to verify compatibility before bulk purchase?
A:Provide excavator model Hitachi EX270LC, swing motor model M2X210 and cross OEM part numbers 4197831 / 4224992 / 9083736; we cross-check full assembly dimensional drawings to avoid mismatched whole units and unnecessary inventory losses.
Q:How does this swing motor assembly perform in cold high-altitude mines and high-temperature dusty quarry yards?
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.
