 these 5 questions, which can help you save a lot of communication costs:

What power and torque do I need?

This is the cornerstone of selection. First, confirm the motor power (kW) and required output torque (N · m) of 

your device. The K series has a power coverage of 0.12~200 kW and a maximum torque of 50000 N · m.

What speed ratio do I need?

Speed ratio=motor input speed ÷ required output speed. The standard speed ratio range of the K series is 

5.36~179.86. Choosing too high a speed is not enough, choosing too low a torque is not enough.

What is my installation space like?

The K series is a right angle output (input axis perpendicular to output axis). If the device layout requires a 90 ° turn, 

the K series is the correct answer. There are various installation methods available, such as footings, flanges, hollow shafts, etc. Coaxial reducer

What is my working condition?

Continuous operation or frequent start stop? Is there any impact load? What is the ambient temperature? These directly determine what service
