Bosch Rexroth MCR-C Series Radial Piston Motor

Application Range & Technical Specifications

1. Application Range (Applications)

The MCR-C series radial piston motor is designed for high-torque, low-speed wheel and track drive systems, especially in applications requiring extreme load capacity, shock resistance, and compact integration into final drives or wheel hubs.

Compared with general MCR-A versions, the MCR-C is optimized for heavy-duty, high-load and harsh working conditions, including mining and large construction equipment.

1.1 Construction Machinery

  • Large wheel loaders
  • Heavy-duty excavators (travel drive systems)
  • Soil compactors and heavy rollers
  • Road milling machines
  • Stabilizers and pavers (auxiliary drive systems)

1.2 Mining Equipment

  • Mining dump trucks (wheel hub drive)
  • Underground mining vehicles
  • Drilling rigs and blast hole drillers
  • Heavy material transport vehicles
  • Ore handling machines

1.3 Agricultural Machinery

  • High-power harvesters
  • Large forage and silage equipment
  • Self-propelled sprayers
  • Heavy-duty tractors with hydrostatic drive systems

1.4 Forestry & Special Vehicles

  • Forestry harvesters and feller bunchers
  • Heavy mulchers and grinders
  • Military off-road vehicles
  • Rescue and fire-fighting vehicles
  • Amphibious or all-terrain vehicles

1.5 Industrial & Material Handling

  • Heavy conveyor drive systems
  • Steel plant transport vehicles
  • Port handling equipment
  • Tunnel boring auxiliary drives
