This is ServoCity SPG400A Gear Drive Pan System (2:1) from ServoCity. The extreme torque from a standard size servo can be easily done with the new SPG400A Servo Power Gearbox Kit. This device increases the stated torque of your servo by adding another set of final drive gears. By utilizing an external potentiometer on the final output shaft the original amount of rotation from the servo remains. The structure is machined from high-strength 6061-T6 aluminum. The hardened 3/8” stainless steel final output shaft is supported by dual ABEC-5 precision ball bearings that not only allow extremely smooth operation but can also support up to 200 pounds of vertical and horizontal load. The military grade potentiometer is coupled to the final output shaft.

The main spur gear is bolted to the drive hub so that all power transfer is direct without the possibility of slipping. With six optional gear ratios, you are sure to find the right combination of power and speed for your project. The gear ratios can easily be changed if you need to vary the power or speed. The various mounting  attachments are simple with the four 5-40 tapped holes in the aluminum clamp hub. The mounting tabs on the frame are .250” thick. The servo not included (full instructions included).

The normal operation of most servos is 90° but they can operate to 180° when given a pulse signal ranging from 700usec to 2300usec. Since most R/C controllers cannot generate this wide of signal range, you will need to purchase our servo stretcher for 180° operation.

Note: 90° Tube Clamp hubs and hollow 5/8” diameter tubing, 8” Dual ABS Arm, Round ABS Platform and 90° Aluminum Mounting Plate are not including with SPG400A Gear Drive Pan System as shown in images.
