MS MSE MS02 MS05 MS08 MS11 MSE02 MSE05 Series Low Speed Radial Piston Hydraulic Motor MS18

Product Overview

Core Advantages (Solving On-Site Pain Points)

1. Smooth Low-Speed Operation & Strong Starting PerformancePiston and cylinder design eliminates lateral forces, with torque transmitted via rolling bearings—achieving mechanical efficiency above 0.92 and volumetric efficiency up to 0.98. No crawling or jittering even at speeds as low as 0.1 rpm, perfect for winches, traction systems, and low-speed rotation mechanisms that require stable load handling from startup.
2. High Torque Density & Compact DesignMaximum working pressure of 450 bar enables exceptional torque output in a compact footprint, facilitating easy integration into space-constrained equipment. The "no gearbox" direct drive design reduces transmission loss, lowers maintenance costs, and enhances operational safety.
3. Robust Reliability & Contamination ResistanceAdopting planar valve distribution and plastic piston ring seals, the motors feature minimal leakage and strong resistance to oil contamination—critical for harsh environments like mines, ports, and construction sites. Dual tapered bearing structure withstands high radial forces, while modular components ensure quick repairs and reduced downtime.
4. Flexible Configuration & Wide AdaptabilityModular design supports wheel or shaft output options, with integrated service and parking brakes available. Compatible with bidirectional operation and freewheeling functionality (depending on system configuration), the series covers diverse needs: from small rotary actuators to large torque drives (hoisting, traveling, slewing).
