PRE Series

PRE-SeriesPRE is part of the latest generation economy product family from NIDEC-SHIMPO. The PRE redefines the economy planetary gearbox segment by featuring helical cut gearing and a robust internal structure. Our customers benefit from a cost-effective, flexible, reliable design that can be adapted into a wide range of servo and stepper motor axes.

The PRE features industry-standard output mounting geometry with simple adaptation to any motor. Frame sizes from 062-160, along with ≤ 8-10 arc-minute backlash, allow the PRE to cover a broad range of application requirements where cost is a key consideration. As with all NIDEC-SHIMPO planetary products, PRE is designed for maximum heat reduction and running efficiency through the use of special sealing and lubrication technology.

Available Frame Sizes: 062 | 082 | 120 | 160

Product Features

  1. PRE-Cross-sectionCarburized helical gears for higher accuracy and smooth, quiet operation
  2. Uncaged needle roller bearings provide excellent torque density and torsional rigidity
  3. Unique labyrinth input design greatly reduces heat and increases system efficiency
  4. Optimized mounting system with active centering on motor pilot diameter guarantees alignment of motor. Motor can be installed in any orientation
  5. True concentric motor shaft clamping connection, optimized for your specific motor. Reduced inertia for dynamic performance and balanced for high speed operation
  6. Ring gear machined directly into the housing, not welded or pressed in. Provides greater concentricity and elimination of speed fluctuation
