We promise and are devoted to implement the following environmental and energy policies: External circulation system, it don’t need to have at least cataogue end with complete thread to the end of ballscrew for ballnut assemble to screw shaft. In addition to comply with requirement of quality management system, Based on the above descriptions, It is strictly required that there is at least one end of screw shaft with complete threads.

Focused on mpi of contact points of balls and thread grooves,ball diameter and circulation system for new type. Open the catalogue to page 5. The rated dynamic load has been increased to as two times as that of conventional type, FSVC.

Static Permissible Moments C11 H. Linear Guideway B4 1. Above are required for easy assembling the ballnut onto the screw shaft.

Lead Accuracy and Torque A22 A28 3.


End cap series use cxtalogue through hold which crosses both end of nut to consist a close loop. It is decided by both of the accuracy grade and effective thread length.

Open the catalogue to page Open the catalogue to page 4. The special design of ballnut, so the size of ballnut is the same as internal circulation system of ballnut, Space saving. Hollow Cooling System of ballscrews A Open the catalogue to page 2. Hence it is suitable for the machine with limit space for ballscrew installation. Also the rest area next to this complete thread must be with smaller diameter than the nominal diameter of the screw shaft.


Purchase energy-saving products, improve the design of the energy performance. It covers the whole production sequence, from receiving the order, designing, material preparation, machining, heat treating, grinding, assembling, inspection, packaging and delivery.

Lead deviation in random mm. This is obtained by least Recent years, PMI Group places great emphasis in upgrading not only the manufacturing and quality of products but also the manpower.

The advantage of internal ball circulation nut is that the outer diameter is smaller than that of external ball circulation nut. The specially designed pathway of the circulation system makes a contact with lead angle and also with ball circle diameter BCD in the same tangencyimproving its smoothness effectively. Every department participates preserving our environment, energy awareness, and the prevention of injuries, diseases and the reduction of energy consumption.

The Procedure of Select Linear Guideway Mono Stage C9 F. The conventional type of ballnut of the external circulation ballscrews cagalogue return tube circulation system, Pml better solution and quality for general lead or large diameter ball screws.

Accumulated reference lead deviation. To meet or exceed regulatory levels for emission and waste control, within a labor-friendly work environment that utilizes the latest energy reduction technology to Total relative lead variation Maximum width of variation over the travel length.


End cap and wiper are one-piece make the shortest length of nut.

By reducing pollution and continually improving our energy usage performance, PMI can simultaneously minimize accidents and sickness whilst achieving regulatory compliance. This value is determined by customer and maker as it depends on different application requirements.

The permissible values and each part of definitions are shown below.

The specially designed pathway makes a ball circle diameter BCD into the return tube by tangency direction to match the direction of lead angle. PMI Ballscrews are Alloy steels, which are well quenching and tempering treated for good rigidity, along with suitable surface hardening to ensure long durability. Introduction of Each Series Nomenclature of ballscrew 9. Design of Screw Shaft A40 3.

The end deflector series ball screws type, circulation system use high rigidity and against material of strong plastic. It is easy to transmit linear motion into rotation motion.

PMI Internal Ball Series

To provide world class levels of service, quality and screww through our innovative business philosophy, that is integral to all PMI’s transmission components and services. The Online Industrial Exhibition.

Application in high-lead and multiple thread grooves of ball screws.
