💡 What is a bellows-type flexible coupling used for in servo and stepper motor drives?

It helps transmit torque while absorbing misalignment for smoother, more accurate motion.

• Transfers torque with minimal backlash
• Accommodates angular misalignment and end play
• Ideal for CNC, robotics, automation, and 3D printers
• Compact and reliable, Made in Japan

This handy coupling keeps motion precise under load and over time.
