BDB planetary gearbox


  • Rotating output flange instead of traditional output shaft enables unique power transmission solutions
  • Satellite gears have dual support in a massive cage providing high stifness : the gears remain in-line even in case of peak torque
  • Output flange rotates on tapper roller bearings for maximal radial and axial loads.
  • Very low backlash (5 to 1 arc-min max*)
  • High radial load acceptance
  • High axial load acceptance
  • High torsional stiffness
  • Up to 14 different ratios from 3 to 220.
  • ISO or DIN output interface
  • Easy 1 minute clamping into motor shaft (self locating input flange)
  • Significant temperature range from -31°F to 266°F ,depending on options (-35°C to 130°C)
  • Reinforced waterproofness (IP 65)
  • Washdowned stainless steel version IP-67 & 1500 psi water jets available.
  • Optional lubricating grease for the food-processing industry
  • Easy maintenance

like any standard mijno gearbox, the bdb range offers:

  • A high level of quality/traceability, 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 excellent 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.
