FAQ
Q:What lubrication standard should be used for heavy-duty swing reduction gearbox maintenance?
A:High-viscosity anti-wear hydraulic oil meeting ISO VG 46 or VG 68 is typically recommended.
Q:Can this swing motor assembly be rebuilt or refurbished after mining wear damage?
A:Yes, core components such as gear sets and bearings can often be rebuilt depending on wear level.
Q:How does EX600H swing drive performance change under extreme low-temperature environments?
A:Low temperatures may slow hydraulic response, so preheating and proper oil selection are required for stable operation.
A: We provide original, OEM, and high-quality aftermarket versions with stable supply capability.
