Details

Extreme torque and up to 400° rotation from a standard size servo....easily done with the BM-400-400 bottom mount Servo Gearbox kit. The gearbox frame is machined from high-strength 6061-T6 aluminum for superior strength and durability. The hardened stainless steel output shaft is supported by dual ABEC-5 precision ball bearings that allow extremely smooth operation with load bearing capabilities of up to 200lbs. The precision potentiometer is mounted inside the underdrive housing which is then attached to the final output shaft to provide accurate positioning feedback. Five different gear ratios are available in order to find the right balance between speed and torque. The brass hitec pinion gear meshes to a high-grade 7075 aluminum 32 pitch hub gear which is fastened to the output shaft of the gearbox with a 3/8” clamping hub. The .770” clamping hub has 6-32 tapped holes which allow easy attachment of various components.  The gearbox can be mounted using the bottom-mount tabs which are .147” thick and have .140” thru-holes (allows a #6 screw to be used). The BM-400-400 kit will come with full assembly instructions. Servo not included. Patented.

Note: The BM-400-400 kit, when assembled, will allow the final shaft to rotate approximately 200 degrees using a hitec digital servo with stock programming. To increase the rotation (when using a digital servo) you can use a hitec servo programmer to re-program the endpoints. Maximum achievable rotation is approximately 400 degrees. If you are not comfortable soldering and handling delicate parts, we would suggest purchasing a fully assembled Servo Gearbox.
