Purchase now: Wittenstein CP025S-MF1-5-1E1-2S Gearbox
Purchase now: Atlantech Drives provides you the Wittenstein Alpha CP025S-MF1-5-1E1-2S, a high-capacity **Planetary Gearbox** from the **alpha Basic Line**. This unit belongs to the **Size 025** frame, offering significantly higher torque capabilities and radial load resistance compared to the smaller 015 series. With a reduction ratio of **5:1** (single stage), it is optimized for high-speed dynamic applications such as belt drives, packaging machines, and delta robots where throughput is critical.
Technical Specifications and Size 025 Capabilities
The CP025S is a robust component designed to handle the demands of modern servo automation. The **»-5″** ratio implies that for every 5 rotations of the servo motor, the output shaft rotates once, multiplying the torque by a factor of 5 (minus efficiency losses). The **»-1E1″** suffix is the **Motor Interface Code**. It dictates the specific dimensions of the input clamping hub and the adapter plate bolt circle. You must verify that your motor’s shaft diameter and pilot align exactly with the «E» specification of the CP025 series.

Expert Tips: Thermal Limits at High Speed
Watch the heat. Expert Tip: A 5:1 ratio gearbox often runs at very high input speeds (e.g., 3000-4000 RPM) to achieve the desired output. While the Wittenstein CP025S is highly efficient, continuous high-speed operation generates internal heat due to oil churning and seal friction. Ensure the gearbox is mounted to a substantial metal machine frame to help dissipate heat. If the case temperature exceeds 90°C, consider adding a cooling fin or checking the duty cycle (S1 vs S5).
Frequently Asked Questions (FAQs)
Q: What is the torque rating for Size 025?
A: The CP025 generally handles nominal torques in the range of 30-40 Nm (depending on the exact sub-generation), with emergency stop torques significantly higher. Check the specific datasheet for the «2S» generation limits.
Q: Can I replace a CP015 with this?
A: Not directly. The CP025 has a larger output shaft diameter, a larger centering pilot, and a larger bolt circle. It is physically bigger and will not fit existing CP015 mounting holes.
