Frequently Asked Questions about F Series Industrial Reducer



Q1: What motors can be paired with the F series gearbox?

A: Can be equipped with three-phase asynchronous motors, single-phase motors, explosion-proof motors, variable frequency motors, brake motors, servo motors, etc.


Q2: How to determine if the selection is correct?

A: Core verification three points: ① Allowable torque of reducer>Load required torque; ② The utilization coefficient fB is greater than the working coefficient fBn; ③ The motor interface matches the installation method.


Q3: What is the difference between the F series and the R series?

A: The F series has a parallel axis design (input and output shafts are parallel), while the R series has a coaxial design (input and output shafts are on the same axis). The F series is more suitable for scenarios where installation space is limited and off-axis output is required.


Q4: Can you provide selection assistance?

A: Of course. Just provide information such as motor power, output speed/ratio, load type, installation 

method, etc., and we can provide professional selection advice for free.
