SPX Series Servo Reducer FAQs

Straight answers to what buyers ask us most about Servo Reducer.

A servo reducer is a gearbox mounted between a servo motor and the load to reduce speed and multiply torque, so a smaller servo motor can drive a heavier axis accurately. RB Automation offers servo reducers in 42SPX, 60SPX, 90SPX and 120SPX sizes, with the motor input and output mounting dimensions listed so you can match them to your servo motor.

Four sizes are listed. The 42SPX has an 8 mm input shaft and 10 mm output shaft, the 60SPX has 14 mm shafts on both sides, the 90SPX has a 19 mm input and 20 mm output shaft, and the 120SPX has a 22 mm input and 25 mm output shaft. Lengths L1/L2 are 59/80, 77/95, 110/130 and 152/207 mm respectively.

Compare your motor's shaft diameter, boss diameter and flange bolt circle with the reducer's input side. For example, the 60SPX takes a 14 mm shaft, a 50 mm boss and M4 screws on P.C.D.70, while the 90SPX takes a 19 mm shaft, a 70 mm boss and M5 screws on P.C.D.90. Then check the output shaft and flange against your machine.

Servo reducer price depends on the frame size (42SPX to 120SPX), the gear ratio, the motor adapter needed and the quantity. No fixed list price applies, so RB Automation quotes each requirement. Send your servo motor model, the required ratio and the output torque or speed through the inquiry form on this page or to contact@rbautomate.com.

RB Automation supplies SPX series servo gear reducers from Ahmedabad, Gujarat, to machine builders and maintenance teams across India. Call +91 8511104864 or WhatsApp +91 9898739737 with your servo motor frame and the reduction you need, and the team will propose a suitable size and quote it on its own or with the servo motor and drive.

Yes, share the load mass or inertia, required output speed, torque and duty cycle, and RB Automation will help work out a suitable reduction ratio and reducer size from the 42SPX to 120SPX range. OEMs needing reducers for multiple machines can also request a bulk quote that includes matching servo motors and drives. Email contact@rbautomate.com.
