Purchase now: Wittenstein CP035S-MF1-5-1G1-2S Gearhead
Purchase now: Atlantech Drives provides you the Wittenstein Alpha CP035S-MF1-5-1G1-2S. This is a powerful **Size 035 Planetary Gearbox**, a step up in frame size from the 015/025 series. Designed for medium-to-heavy duty automation, it features a reduction ratio of **5:1** (Single Stage). The larger Size 035 housing allows for larger internal bearings, which translates to a significantly higher capacity for radial and axial loads on the output shaft, making it ideal for direct belt drive tensioning or heavier rack and pinion systems.
Technical Specifications and Size 035 Capabilities
The CP035S offers a perfect balance of performance and cost. With the **Ratio 5**, it provides high-speed throughput. The **»-1G1″** code is the **Motor Interface** specification. The «G» interface typically accommodates larger servo motor shafts (often 19mm or 24mm, but verify datasheet) compared to the «E» or «C» interfaces found on smaller units. The gearbox is factory-lubricated for life with synthetic grease, allowing for maintenance-free operation in any mounting orientation (vertical or horizontal).

Expert Installation Advice: Radial Load Check
Don’t kill the bearings. Expert Tip: The CP035S is tough, but every gearbox has a «Radial Load Limit» (measured in Newtons) at the output shaft. If you are mounting a timing belt pulley directly onto the shaft and tensioning it, ensure the tension force does not exceed the specification. Excessive tension will cause the output bearings to fail prematurely (pitting/noise). Mount the pulley as close to the gearbox face as possible to minimize the lever arm effect.
Frequently Asked Questions (FAQs)
Q: What is the difference between CP025 and CP035?
A: Physical size and torque. The CP035 has a larger output shaft diameter, a larger bolt circle for mounting, and can transmit roughly 2x to 3x more torque than the CP025.
Q: How do I know if my motor fits the 1G1 interface?
A: You must measure your motor’s pilot diameter, bolt circle diameter, and shaft diameter/length. Compare these strictly with the Wittenstein mounting drawing for code «1G1».
