Details

This limited edition servo gearbox is a must-have! The BM-2252-3 servo gearbox utilizes the convenience and simplicity of a hobby-style servo and boosts its capabilities by isolating the load on a ⅜” output shaft which is driven by a 3:1 gear reduction.  

The goBILDA 2000-0025-0002 servo is a perfect match to the gearbox, given it has steel gears, 300 degrees of rotation and 350 oz-in of torque. Consider the 3:1 ratio and you have 100 degrees of rotation left with a whopping 1050 oz-in of torque at the output shaft of the gearbox! Unlike some of the servos we’ve included with our gearboxes in the past, this one requires no modifications; just bolt it in and you’re ready to go!

As an added bonus, we’ve included a free goBILDA Servo Programmer. This little programmer is easy to use and allows you to toggle back and forth between feedback mode (as mentioned above) and continuous mode. In continuous mode, the servo is able to rotate without limits in either direction. The speed, up to 60RPM (20RPM at the output shaft of the gearbox given the 3:1 ratio), will be determined by the PWM signal that your controller sends.

Bolt the servo gearbox down to a flat surface with #6 screws or modify the tabs to your heart’s content to match the custom build you plan to power! On the top side, utilize the Actobotics 0.77” pattern hub to fasten an arm, channel, pulley or disc to.
