High Torque Travel Motor Gearbox Planetary Final Drive Assembly For Heavy Duty Track Reduction

R385-9 Final Drive Track Gearbox Assembly Excavator Travel Reduction Excavator Travel Gearbox

We solve this with case-hardened alloy steel gears and high-capacity tapered roller bearings. This robust construction significantly extends service life compared to standard aftermarket units, lowering your total cost of ownership by reducing unplanned replacements and lubrication leaks. Expect smoother rotation and higher torque transmission even in mud, sand, or rock conditions.
ISO 9001:2015 certified manufacturing facility- ensuring consistent quality control from raw material to final assembly.
Each R385-9 final drive gearbox complies with CE machinery safety directives (relevant for European markets).
Manufactured to meet or exceed OEM performance standards for dimensional accuracy, hardness, and sealing integrity.

1. Abnormal or excessive noise generation: Gear wear, bearing failure, insufficient lubrication or oil quality deterioration.
2. Oil leakage malfunction: Degraded sealing parts, housing cracks, excessively high lubricating oil level.
3. Sluggish traveling / Track deviation phenomenon: Worn gears or bearings, brake release failure, performance difference between left and right reducers.
4. Overheating malfunction: Overload operation state, poor lubricating effect, insufficient heat dissipation, brake dragging failure.
5. Gear jumping or blocking failure: Cracked gear teeth, defective planet carrier, foreign matter entering the gearbox.
