・MMF046 fixed displacement axial piston vibration hydraulic motor, OEM replacement, perfectly matched with supporting vibration pump for SAKAI SV500 road roller vibration system
MMF046 hydraulic vibration motor is designed for SAKAI SV500 compaction vibration circuit. It converts hydraulic pressure into rotary torque to drive eccentric block. Stable excitation force ensures consistent compaction performance during continuous road rolling operation.
・Precision hardened piston and cylinder block assembly, steady excitation force output
Alloy steel piston and cylinder block adopts precision grinding and surface hardening process. It maintains steady torque output under impact load. High volumetric efficiency guarantees stable vibration frequency for compaction work.
・High-rigidity cast iron housing with stress relief treatment, excellent anti-vibration and impact resistance
Cast iron housing after stress relief annealing eliminates internal residual stress. It can resist strong cyclic impact and continuous vibration on road construction sites. The housing is not easy to deform, slowing down wear of internal piston, valve plate and bearing components and extending service life.
・Heavy-duty anti-impact design, stable vibration output for long continuous compaction operation
This vibration motor adopts rugged heavy-duty impact-resistant structure, reliable vibration output during long continuous rolling work. It provides stable rotary power for eccentric block. It maintains vibration hydraulic system operating normally, preventing insufficient compaction force caused by torque loss, ideal replacement for overhaul and daily maintenance of SAKAI SV500 road roller.

FAQ 

Q1: What machine does MMF046 vibration motor fit?
A1: It is specially designed for SAKAI SV500 single drum road roller. Confirm spline shaft and oil port layout before ordering.

Q2: What is the main function of MMF046 vibration motor?
A2: It drives the eccentric mass in steel drum to produce high-frequency vibration, completing soil and asphalt compaction for road construction.

Q3: Why does the roller have weak compaction force after motor replacement?
A3: Check if the vibration pump output flow is sufficient. Also check for air trapped inside the closed circuit and internal wear of the motor.

Q4: What needs attention when installing MMF046 vibration motor?
A4: Clean the closed hydraulic circuit thoroughly, replace hydraulic oil and filter. Bleed air completely to avoid cavitation damage to internal components.

Q5: How to maintain the vibration motor for road roller?
A5: Monitor oil cleanliness strictly. Inspect shaft seal regularly. Replace hydraulic oil and filter periodically to reduce wear of friction pairs.
