Purchase now: Wittenstein NP005S-MF1-5-1B1-1S Gearhead
Purchase now: Atlantech Drives provides you the Wittenstein Alpha NP005S-MF1-5-1B1-1S. This is a high-speed **Size 005 Planetary Gearbox** configured with a reduction **Ratio of 5:1**. Ideal for dynamic applications where speed is the priority, this unit allows small servo motors to drive belt actuators or grippers with rapid acceleration capabilities. The NP005S combines the legendary Wittenstein reliability with an economical design suitable for standard automation axes.
Technical Specifications and Interface 1B1
The «5:1″ ratio is achieved in a single stage, ensuring minimal friction loss and maximum thermal efficiency. The defining characteristic here is the **»-1B1″ Motor Interface**. Unlike the ‘0C1’ version, the ‘1B1’ interface is machined to accept a different motor geometry (likely a slightly larger or different brand of micro-servo). Using the modular adapter system, Wittenstein ensures that the pinion gear is perfectly positioned relative to the sun gear, regardless of the motor brand, provided the code matches.

Expert Installation Advice: Thermal Dissipation
Small body, high heat. Expert Tip: Size 005 gearboxes have very little surface area to dissipate heat. If you run this unit at a Ratio 5 with high input speeds (e.g., 4000-5000 RPM continuous), it can get hot quickly. It is critical to mount the gearbox flange to a metal machine plate that acts as a heatsink. Do not mount it on plastic or insulating spacers if you plan to run near the nominal speed limit.
Frequently Asked Questions (FAQs)
Q: Can I change the adapter plate from 1B1 to 0C1?
A: Technically, the adapter plates are interchangeable parts, but Wittenstein usually supplies the unit as a sealed, tested assembly. Changing the plate yourself risks introducing misalignment or contamination. It is safer to buy the correct complete unit.
Q: What is the life expectancy?
A: Under rated load conditions (S1 duty), the service life is typically 20,000 to 30,000 hours.
