Nidec high precision gearboxes utilize different types of gearing technologies – planetary, worm, rotary stage – yet each achieves the highest level of precision and performance within its competitive class. They offer a wide variety in terms of frames and ratios, input options, and availability are truly unparalleled within our industry. Regardless of your type of equipment and the motion profile of your application, you will find the perfect fit within this high precision product category.

VRL Series Inline Planetary GearboxesVRL Series

The VRL series is the all-rounder in the planetary gearbox marketplace. With helical gearing, robust internal construction, smooth operation and high torque density, this product is truly best-in-class. 5 arc-min backlash allows the VRL to be applied to a wide range of applications where accuracy and dynamics are in play, but cost is of concern. The VRL is an excellent choice for servo applications in packaging, handling and automation systems. A variety of standard wash down and food grade options are available, making it an attractive option for the toughest environments. We offer the broadest selection of frame sizes and ratios, giving our customers more flexibility than ever before. Industry standard mounting dimensions allow the VRL to be implemented in legacy machine designs, saving our customers valuable time.

ERH Series Cycloidal Gearbox

ERH Series

The ERH series is a compact, robust cycloidal reducer designed for servo applications. This product features high reduction ratios in a compact form factor. Its key advantage is exceptional shock load capacity, which eliminates the need to oversize the reducer for that requirement. The dual pin housing of the ERH cycloidal provides the ability to adjust one wheel against the other, allowing us to reduce the output shaft backlash to less than 6 arc-minutes. Rolling contact contributes to minimal friction and high efficiency. Torque transmission elements experience compression—they do not shear. The long output shaft bearing span provides solid overhung load capability.

The ERH is ideal for applications operating in heavier industrial environments, but requiring servomotor mounting and good accuracy. Its compactness offers advantages against helical gearing, which requires additional stages to achieve higher reduction ratios. Its high efficiency against worm gears allows our customers to downsize and still enjoy larger output power. The end result is longer service life and tremendous energy saving.

EV Series Right-Angle Planetary Gearboxes

EV Series right angle

NIDEC-SHIMPO has developed an impressive right-angle planetary gearbox offering. The core right-angle products are established from the base design of their inline equivalents. Similar to our Inline offering, our EV right-angle series have some differences in terms of internal bearing design, output mounting, among others that differentiate each series from the other. The different series are available in the same frame size variety and most of the ratios as offered with the inline. The EV right-angle product family is an excellent option when space is a key design constraint for the equipment manufacturer.

FLEXWAVE Strain Wave - Harmonic Gear UnitFLEXWAVE

The NIDEC-SHIMPO FLEXWAVE is a very compact harmonic gear reduction mechanism that achieves zero backlash, as well as exceptional accuracy and repeatability. The FLEXWAVE consists of three major internal elements – the elliptical wave generator, the flexspline, and the circular spline. The elasticity properties of the flexspline and the teeth differential between the flexspline and the circular spline result in the unique reduction characteristics. When compared to other reduction technologies, the FLEXWAVE offers the following advantages:

  • Zero backlash
  • High efficiency ratings
  • High reduction ratios in a compact footprint
  • Exceptional repeatability and positional accuracy
  • Light weight with superior torque density

EJ Series Right-Angle Worm Gearboxes

EJ Series

The EJ Series servo grade speed reducers are ideal for the most challenging of motion control applications. Each series incorporates a globoidal worm gear mesh design in order to achieve the torque handling capacity and the highest levels of precision that our SHIMPO customers have come to expect from us. The input design of our EJ right-angle gearbox applies the same concept of motor modularity that is common across our High Precision product family, meaning our customers and distribution partners get the same level of flexibility, product variety, and overall availability that is unparalleled within our industry.

ST Series Rotary Index Tables

ST Series

NIDEC-SHIMPO first developed its STH series off-set hollow bore rotary gearbox for a variety of robotic handling applications that were commonly encountered within the semiconductor industry. When eventually released to general industry, this rotary stage gearbox design became extremely popular with many Custom Assembly and Test equipment builders. These OEM customers often wanted to apply the STH to a tooling fixture, end-effector, dial, etc., within their custom equipment. SHIMPO quickly expanded the variety of ratios supported for the series and the configurations available at the input side, in order to provide more flexibility and options for these turn-key projects.

SHIMPO has expanded its indexing product offering with the STR, to handle those applications that require larger overall torque carrying capacity with even finer levels of precision.

Traction DrivesTraction Drive

The Traction Drive mechanism produces smooth rotation and eliminates speed irregularity due to the high frequency vibration inherent in gear transmission. This is how the traction drive provides high rotational accuracy with low noise. Transmission through either cones or planet rollers being contacted under pressure allows the system to eliminate backlash when paired with full closed loop control. This allows the differential to approach zero backlash and achieve extremely high positional accuracy. The traction drive technology, in summary, provides many benefits over your tradition planetary gearbox;

  • Capable of handling higher input (>6,000 rpm, no problem) and output speeds
  • Exceptionally smooth rotation for better speed control
  • Higher reduction ratios in the 1st stage
  • Variable speed output
  • Much lower backlash (to the arc-sec)
