SPG805BB Servo Power Gearbox Standard Rotation 5:1 Assembled

1,700+ oz-in. of torque from an inexpensive giant-scale servo...easily done with the SPG805A Servo Power Gearbox.  The gearbox frame is machined from high-strength 6061-T6 aluminum for superior strength and durability. The hardened 3/8" 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 protected by an aluminum housing mounted over the final output shaft to provide accurate positioning feedback. The 5:1 gear ratio is made up of a brass hitec servo gear with the D1 spline meshed with a 7075 aluminum 32 pitch hub gear. The hub gear is fastened to the output shaft 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 top-mount tabs which are " thick and have .140" thru-holes (allows a #6 screw to be used). The SPG805A can be purchased in kit form which will require assembly (full instructions are included) or as a fully assembled unit ready to operate. Patented. NOTE: The SPG805a, when assembled, will allow the final shaft to rotate approximately 90 degrees using a Hitec servo. The rotation can be increased by using a servo stretcher or by sending a wider PWM signal range (up to 600-2400usec). * 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.
