smaller footprint and 20% higher power density than competitors.
Modular assembly allows 2-hour MTTR, ideal for confined marine
engine rooms or mobile construction machinery.
The Analysis For Rexroth A6VM Piston Motor Common Breakdown:
1. Improper installation of the A6VM motor may cause misalignment
or stress on internal components, leading to abnormal vibrations
and increased wear; if the hydraulic pump is not correctly
calibrated, the resulting pressure fluctuations can intensify
damage, demanding precise realignment and system diagnostic checks
to prevent further deterioration immediately avoid failure.
2. Contaminated lubrication may cause the A6VM motor’s moving parts
to seize or operate erratically, resulting in reduced performance
and potential internal damage; when coupled with issues in the
piston pump, poor lubrication accelerates wear, making routine
fluid analysis and timely lubricant replacement essential for
maintaining system integrity to ensure continuous operation.
3. Excessive Vibration (＞8 mm/s): High axial vibration could be
misalignment (>0.05 mm) or bearing race spalling. Use laser
alignment and FFT analysis to check piston-pass frequency
harmonics.
