Poclain Hydraulic Motor MZE02-2-BJF-F20-9AP0-3DFH
Product Overview
Poclain MZE02-2-BJF-F20-9AP0-3DFH is a low-speed high-torque radial piston hydraulic motor, specially designed for slewing drive applications of small and medium construction Machine. As the core executive component of the excavator slewing hydraulic system, this motor converts hydraulic pressure energy into large torque rotary power, realizing 360° stable rotation of the upper platform of engineering equipment. It integrates built-in relief valve, check valve and parking brake, with compact structure, strong shock resistance and excellent anti-pollution performance. It is widely used for original equipment matching, field overhaul and aftermarket spare replacement of mini excavators, aerial work platforms and other mobile Machine. The reliable operation of this hydraulic motor directly guarantees the stability and safety of the whole slewing hydraulic system.

Working Principle
High-pressure hydraulic oil from the main control valve of the hydraulic system enters the oil port of this hydraulic motor, pushes the radial piston group to act, drives the cylinder block to rotate and outputs high torque through the pinion shaft. The built-in relief valve limits the maximum system pressure to avoid overload damage to the Machine; the parking brake automatically locks the motor when the machine stops rotating to prevent platform sliding. When internal pistons, cam rings or sealing parts are worn, the motor will suffer faults such as weak slewing power, slow rotation speed, oil leakage and abnormal noise. Replacing a qualified Poclain MZE02 motor can fully restore the slewing performance and keep the hydraulic system running stably.
Core Advantages
1. Original Poclain professional swing drive design, integrated valve group simplifies the pipeline layout of the hydraulic system, reduces assembly difficulty of the Machine.
2. Low-speed high-torque radial piston structure, large starting torque, stable operation at low speed, suitable for frequent forward and reverse rotation of excavator slewing mechanism.
3. Built-in anti-shock relief valve and parking brake, effectively absorb hydraulic impact, improve operation safety, protect the hydraulic system from pressure shock damage.
4. High-precision friction pairs and heavy-duty sealing structure, strong contamination resistance, adapt to dusty and harsh construction site environments, extend service life of the hydraulic motor.
5. Strictly follow original dimensional standards, excellent interchangeability, direct replacement without secondary processing, convenient for on-site maintenance and overhaul of engineering equipment.
Application Range
Poclain MZE02 series hydraulic motor is a key slewing power component for mobile hydraulic system. It is specially applied to the slewing mechanism of 3–6 ton mini excavators (such as SDLG LG35), aerial work vehicles, small crane equipment and other construction Machine. It is supplied for machinery OEM manufacturers, maintenance repair shops and global aftermarket spare parts trading business.
