Product Overview
The KYB MAG-18VP-350F-4 is a high-torque, variable displacement axial piston hydraulic travel motor engineered by KYB (Kayaba Industry Co., Ltd.), a globally recognized tier-one manufacturer of precision hydraulic components for mobile and industrial machinery. This motor is purpose-built for the final drive circuit of tracked and wheeled construction equipment, converting pressurized hydraulic fluid into controlled rotary mechanical output to propel the machine. Its variable displacement axial piston design incorporates an integrated swashplate mechanism and a two-speed displacement control, allowing the operator to shift between high-torque/low-speed and low-torque/high-speed travel modes. The MAG-18VP-350F-4 is a direct-fit replacement unit for OEM final drive assemblies, delivering the ruggedness, precise controllability, and long service life demanded in demanding earthmoving and industrial drive applications.

Engineering Features & Advantages
- Precision Performance: Variable displacement axial piston design with swashplate control delivers smooth, stepless torque output and precise travel speed modulation, enabling accurate machine positioning and efficient grade control.
- Two-Speed Travel Capability: Integrated high/low displacement selection allows the operator to switch between maximum tractive torque for climbing and digging, and higher travel speed for rapid repositioning on site.
- Integrated Brake & Crossover Relief: Built-in spring-applied, hydraulically released parking brake and crossover relief valves protect the motor and final drive from pressure spikes and ensure safe holding on gradients.
- Industrial Reliability: Constructed with hardened piston bores, precision-ground swashplate surfaces, and heavy-duty bearings for continuous operation under severe industrial conditions, shock loads, and high duty cycles.
- Direct Fit Replacement: Exact dimensional and functional compatibility with original KYB OEM standards, ensuring drop-in installation without modification to the final drive housing or hydraulic circuit.
Typical Industrial Applications
The KYB MAG-18VP-350F-4 hydraulic travel motor is widely deployed in the final drive systems of compact and mid-size tracked excavators, mini excavators, crawler carriers, and skid-steer loaders. It is also found in tracked drilling rigs, agricultural crawler tractors, and specialized industrial mobile platforms where precise, high-torque propulsion and reliable two-speed travel control are essential. Its robust construction makes it suitable for construction, mining, forestry, and
