Originating from Germany with over 110 years of precision manufacturing heritage, the Stephan STEP series precision gearboxes, with their groundbreaking performance, have become the core choice for top international robotics companies such as ABB and KUKA. With standardized and modular designs adapted to global automation scenarios while also allowing for flexible customizations, they are redefining new heights in robotic joint transmission!

Maximizing core advantages, setting a new standard for precision transmission

1. Patented constant accuracy, precise without deviation

Leveraging core patented technology to maintain constant accuracy, the planetary-like structure design ensures backlash is precisely controlled under 0.1 arc minutes (only 6 arc seconds). According to customer laser interferometer tests, the five-axis machine tool head achieves single-axis repeat positioning accuracy of 3.2 arc seconds and dual-axis 6 arc seconds. Whether operating at high speed or during long-term tasks, it maintains stable and precise performance.

2. Extremely long service life, durability surpassing peers

Under normal working conditions, its service life exceeds similar industry products by more than three times; when factoring in rotational speed, the lifespan can rise to more than six times. With superior wear resistance and stability under the same external conditions, it significantly reduces equipment replacement costs and extends the operational lifespan of the entire machine.

3. Compact and lightweight, upgraded load capacity

The planetary-like structure offers the optimal solution for the smallest volume at the same torque! Under the same torque load, the STEP gearbox is smaller, lighter, and has higher power density. Compared to cycloidal gear types, the disc size is reduced by 10%. Remarkably, the 575Nm STEP gearbox has a smaller disc size and weight than a 100Nm CKD DD motor. When mounted on a robot, its own weight is reduced, enabling it to easily handle larger external loads, significantly improving operational efficiency.

4. Maintenance-free for life, directly reducing operating costs

An innovative lifetime maintenance-free design completely eliminates productivity losses from stoppages for oil changes, requiring no additional personnel or materials, and avoiding construction risks. The selected lubricants are convenient and economical, with Castrol EP 320 recommended by factories, and Nabo SB150 also compatible. These are easy to obtain and competitively priced in the market.

5. Low vibration and leak-proof, maximizing stability

Extremely low operational vibration not only further ensures repeat accuracy but also addresses a major industry issue – oil leakage. Vibration is a primary cause of gearbox oil leaks. The STEP gearbox, with its ultra-low vibration performance, greatly reduces the risk of oil leakage, enabling long-term stable operation and reducing downtime due to faults.

From core components in top robotics companies to customized adaptations for automation equipment across industries, the Stephan STEP precision gearbox is built on a century of technology and proven performance. Choosing STEP means choosing a precise, durable, and highly efficient transmission solution!
