MRP planetary gearbox

MRP low backlash


The MRP is a low backlash planetary gearbox designed for continuous or low-acceleration servo applications. 2 radial bearings on the output shaft provide high acceptance of radial loads (like a spur pinion or a belt).

This range offers:
  • 5 sizes from 5 Nm to 290Nm (continuous)
  • Low backlash (15, 12 or 10 min depending on size and selected option)
  • Convenient output interface, which enables centering on the bearing, for a perfect shaft concentricity.
  • Shaft with or without keyway (with a DIN332D threaded hole standard)
  • IP 54 protection

LIKE ANY MIJNO GEARBOX, the mrp provides
  • A high level of quality, due to the in house manufacturing of all internal mechanical components
  • The highest quality of gears, with carburized, quenched and ground satellite gears, supplying power, precision, reliability and an everlasting, low backlash.
  • Standard components which include bearings, lubricants, seals and joints from the most trusted international suppliers for quality without compromise
  • A high efficiency (up to 96%)
  • Numerous reduction ratios (multiple of 3, 4, 5, 7, 10) (other ratios available optional)
  • A quick, easy and reliable assembly to the motor (without adapting flange)
  • Dual screws coupling providing perfect balancing, perfect centering, and strong grip with the motor shaft,
  • A wide range of temperature  (-20°C à +90°C)(-4°F to 195°F) (more ranges of temperature optional)
  • Numerous available options including lubrication, interfaces, and peinture and more.
  • An optional stainless steel version.
