Purchase now: Wittenstein CP025S-MF1-7-1G1-2S Gearhead
Purchase now: Atlantech Drives provides you the Wittenstein Alpha CP025S-MF1-7-1G1-2S. This is a versatile **Servo Planetary Gearbox** with a reduction ratio of **7:1**. The «7» ratio is often considered the «sweet spot» in automation engineering because it provides a perfect balance between speed reduction and torque multiplication, making it suitable for a vast range of gantry systems and rotary tables. This model fits the **Size 025** form factor, providing robust performance in a compact aluminum housing.
Technical Specifications and The «1G1» Interface
The critical differentiator for this specific Part Number is the **»1G1″ Motor Adapter Code**. In the Wittenstein modular system, the gearbox mechanics (CP025 Ratio 7) are standard, but the **»G»** interface is machined to accept a specific motor geometry (e.g., a larger shaft diameter or a different bolt circle than the «E» or «C» versions). Attempting to mount a motor designed for an «E» interface onto this «G» gearbox will fail—the bolt holes won’t line up, or the shaft bushing will be the wrong size.

Expert Installation Advice: The Clamping Bolt
Torque it right. Expert Tip: The input clamping hub is accessible through a small port on the adapter flange. When installing the motor, you must tighten this screw to secure the motor shaft. **Crucial:** You must use a torque wrench set to the specific Nm value listed in the manual for the CP025 clamping screw. Do not guess. If it’s too loose, the motor will spin inside the hub (slippage). If too tight, you can crack the hub.
Frequently Asked Questions (FAQs)
Q: Why use a 7:1 ratio?
A: 7 is a prime number, which can be beneficial for gear wear patterns (hunting tooth). Functionally, it offers higher torque than a 5:1 but higher speed than a 10:1, often eliminating the need for a bulky 2-stage gearbox.
Q: Is the unit pre-lubricated?
A: Yes, all Wittenstein Alpha Basic gearboxes come factory-filled with lifetime grease. You do not need to add oil before installation.
