MR Series Hydraulic Motors - Frequently Asked Questions

What are the main features of MR hydraulic motors?

MR hydraulic motors are spool valve, roller gerotor motors with the following features:

  • Various mounting options: flange mounting, motors with needle bearings
  • Port types: side and rear ports
  • Shaft types: straight, splined, tapered
  • Shaft seals for high and low pressure
  • Compatibility with metric and BSPP ports
  • Option for speed sensing and other special functions

What applications are MR hydraulic motors typically suited for?

  • Conveyors
  • Feed mechanisms in robots and manipulators
  • Metalworking machines
  • Textile machines
  • Food industry
  • Agricultural machinery
  • Lawnmowers

What operating fluids and filtration requirements apply to MR hydraulic motors?

  • Recommended: mineral oil-based HLP (DIN 51524) or HM (ISO 6743/4)
  • For synthetic oils: consult manufacturer regarding seal material
  • Optimal viscosity: 20–75 mm²/s at 50°C
  • Minimum viscosity: 13 mm²/s at 50°C
  • Filtration: ISO 20/16 (25 µm or finer)

What are the maximum and minimum operating parameters?

  • Displacement: up to 397 cm³/rev
