Reducer

Short Description:

Product Overview

STEP precision gearboxes are designed for the most demanding applications where efficiency, service life, accuracy, and stiffness are crucial. With a full-load efficiency of more than 90%, the gearbox, which has a planetary-gear-like design with integrated helical gear stages, produces remarkable power density through repeated meshing engagements across the sun gear, planet gears, and ring gear. It satisfies the demanding needs of automation, machine tool, defence, and robotics applications by maintaining constant precision throughout its whole service life thanks to unique wear-compensation technology.

Core Technical Advantages

1.Elevated Rigidity Always Reliable Accuracy:

High precision is ensured from the bottom up by a heavy-duty main bearing, integrated bearing inner/outer rings, and exceptionally high tilting and torsional stiffness. Backlash is guarantyd to remain consistent during the whole service life thanks to the proprietary backlash-free construction, a special automated gear-adjustment gearbox technology that eliminates expensive readjustments and drastically reduces downtime.

2.20,000 hours at full load is a long service life：

Under full load, the unit delivers a service life of up to 20,000 hours — equivalent to as many as 60 million load cycles. A patented wear-compensation system keeps precision consistent throughout the entire service life, while low stress on elastic seals helps extend the durability of wearing components and lubricants.

3.High Efficiency · Over 90% at Full Load:

Delivering more than 90% efficiency under full load with extremely low starting torque, it minimizes both energy loss and heat build-up. This high efficiency also allows a smaller drive motor to be used, reducing power consumption and total system cost.

4.Low Noise · Quieter Operation:

The helical input stage makes it one of the quietest precision gearboxes on the market, with noise kept below 65 dB(A) to lower workplace sound levels. It performs both quietly and precisely, staying reliable even at low torque.

5.High Dynamics · Low Moment of Inertia:

Low inertia combined with high output torque enables faster response and stronger dynamic performance, improving overall system controllability. High repeat accuracy and low vibration ensure smooth, stable motion control.

Product Configurations

The STEP series features 8 gearbox variants. These can be supplied as standalone component units or fully enclosed models, with either solid-shaft or hollow-shaft designs to deliver optimal application flexibility.
