Poclain MS18 & MSE18 Series Heavy-Duty High-Torque Radial Piston Motors

Product Overview: The Poclain MS18 and MSE18 Series embody the excellence of radial piston technology, engineered specifically for travel drives requiring extreme torque and superior reliability. The MSE18, as the enhanced/compact variant of the MS18, optimizes installation space while maintaining industry-leading power density. This category features high-precision models: MS18-6-121-R18, MSE18-B-B21-C12, and MSE18-2-12A-R18. These motors serve as the vital power core for heavy-duty road rollers, large rotary drilling rigs, skid steer loader drives, and specialized tracked or wheeled chassis.

Key Technical Advantages:

• Elite Startup Torque (HTLS): The radial piston arrangement ensures 100% rated torque is available from a standstill, effortlessly handling heavy-load starts and incline climbing.

• Dual-Displacement & Specialized Logic: * MSE18-2 (Dual-Displacement): Allows seamless transitions between “Work Mode” (high torque) and “Travel Mode” (high speed).

  • MSE18-B (Specialized Spec): Customized internal architecture optimized for specific industry operational conditions.

• Highly Integrated Braking & Sealing: Suffixes like 2EFJ, 58DEFJM, and 5EJ0 denote sophisticated integrated multi-disc parking brakes and enhanced sealing logic, ensuring absolute safety and longevity in harsh environments (e.g., mud, salt spray).

• Robust Load Bearing: The R18 wheel flange and C12 interface standards utilize ultra-heavy-duty bearings to directly support massive radial and axial loads.

• Target Applications: Wheel excavators, municipal sweepers, mining machinery, forestry harvesters, and heavy-duty industrial mixers.
