Custom Gearboxes

Precipart's speed increasing and decreasing planetary systems, right angle and spur gearboxes can be found in critical applications from avionics to surgical robotics. Our design engineers customize configurations for optimal performance over the life of a program for accurate, repeatable results.

Design engineering support

  • Comprehensive assessment and feasibility studies
  • Reviews of tolerancing stack-up, backlash, hysteresis, total integrated error
  • Life expectancy, speed, torque and duty cycle
  • Load values, directions and vibration

Types:  Speed increasing and decreasing planetary systems, Right Angle gearboxes, Spur gearboxes
