ballscrews pmi FSDU
The combination of lead screw and nut has replaced the traditional ACME screw and trapezoidal screw. This results in smoother operation while reducing friction. Moreover, the new technology has the advantage of faster production speed and lower cost.

Description
Specification:
Feature:
High reliability
PMI has accumulated many years experience in production managing. It covers the whole production sequence, from receiving the order, designing, material preparation, machining, heat treating, grinding, assembling, inspection, packaging and delivery. The systemized managing ensures high reliability of PMI Ballscrews.
High accuracy
PMI Ballscrews are machined, ground, assembled and Q.C. inspected under the constant temperature control (20℃) to ensure high precision of Ballscrews. accuracy inspection certifi cate.
Long durability
PMI Ballscrews are made of German Alloy steels, which are well quenching and tempering treated for good rigidity, along with suitable surface hardening to ensure long durability.
High working efficiency
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.
