PMI BALL SCREW CATALOGUE PDF

Hence it is suitable for the machine with limit space for ballscrew installation. It is strictly required that there is at least one end of screw shaft with complete threads. Also the rest area next to this complete thread must be with smaller diameter than the nominal diameter of the screw shaft. Above are required for easy assembling the ballnut onto the screw shaft. The specially designed pathway of the circulation system makes a contact with lead angle and also with ball circle diameter BCD in the same tangency , improving its smoothness effectively.

High reliability. High accuracy. Long durability. High working efficiency. No backlash and with high rigidity. 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. PMI Ballscrews are machined, ground, assembled and Q. 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.

Balls are rotating inside the Ballscrew nut to offer high working efficiency. It is easy to transmit linear motion into rotation motion. 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.
