Introduction

Balls are rotating inside the Ballscrew nut to offer high working efficiency. Comparing with the traditional ACME screws, which work by friction sliding between the nut and screw, the Ballscrews needs only 1/3 of driving torque. It is easy to transmit linear motion into rotation motion.

No backlash and with high rigidity
The Gothic profile is applied by PMI Ballscrews. It offers best contact between balls and the grooves. If suitable preload is exerted on Ballscrew hence to eliminate clearance between the ball nut and screw and to reduce elastic deformation, the ballscrew shall get much better rigidity and accuracy.

​​​​​​​

● Lower Noise
S series:Optimum design of recirculation path can absorb noise from impact of balls to reduce noise level 5~10 dBA, comparing with general series. 
 

● Quality Tone
The materials of recirculation structure made from composite materials that will keep low audio frequency and supple.
 

● Low Vibration and Smooth Operation
The recirculation path adapts tangency design that reduces impact force from balls, for the reason that the vibration of nut is smoothly.
