SPG985 Power Servo

 

765 oz-in.

 

0.24 sec/60° (2:1 ratio)

Using the very powerful HS-985MG servo in combination with our Servo Power Gearbox is a perfect match resulting in up to 760+oz-in. of power.  This much power can move nearly 50 lbs. with a 1” arm!  Manufactured using only the highest quality components ensures that the SPG985 can handle years of use. Precise feedback is provided by the military grade, stainless steel potentiometer supplied.  The final output shaft is 1/4” stainless steel supported by an ABEC5 ball bearing.  The 48 pitch gears are made from durable Delrin. The SPG985 is designed so that the power from the servo is transferred directly to the final gear and then to your choice of attachment, no power is transferred through the shaft and therefore no slippage will occur.  Gear ratios can be easily changed to vary the power and speed and we offer two rotation options, 90° or 180°. (Patents Pending)

* We highly recommend purchasing this unit assembled by our factory. If you are not accustomed to using a soldering iron or handling delicate parts, please order this product assembled ready to plug into your receiver or servo controller.  It is money well spent. Thanks
