Focused on srcew of contact points of balls and thread grooves,ball diameter and circulation system for new type. Based on the above descriptions, The conventional type of ballnut of the external circulation ballscrews ,using return tube circulation system, Offers better solution and quality for general lead or large diameter ball screws.

Nomenclature of ballscrew 9. Accumulated reference lead cqtalogue. External circulation system, it don’t need cataloguf have at least once end with complete thread to the end of ballscrew for ballnut assemble to screw shaft.

Static Permissible Moments C11 H. Open the catalogue to page A straight line representing the tendency of the cumulative actual lead. Also the rest area next to this complete thread must be with smaller diameter than the nominal diameter of the screw shaft.

This value is determined by customer and maker as it depends on different application requirements. Introduction of Each Series Linear Guideway B4 1. Sfrew Stage C9 F. The end deflector series ball screws type, circulation system use high rigidity and scrw material of strong plastic.

The advantage of internal ball circulation nut is that the outer diameter is smaller than that of external ball circulation nut. This is obtained by least This is allowable deviation of specified travel. PMI Ballscrews are Alloy steels, which are well quenching and tempering treated for good rigidity, along with suitable surface hardening to ensure long durability.



Lead Accuracy and Torque A22 A28 3. The rated dynamic load has been increased to as two times as that of conventional type, FSVC. Design of Screw Shaft A40 3.

In addition to comply with requirement of quality management system, By reducing pollution and continually improving our energy usage performance, PMI can simultaneously minimize accidents and sickness whilst achieving regulatory compliance.

PMI Internal Ball Series

Open the catalogue to page 4. To provide world class levels of service, quality and pmk through our innovative business philosophy, that is integral to all PMI’s transmission components and services.

It’s cataloogue involved in manufacturing of ballscrews, linear guideway and mono stage, which is the critical component of precision machinery and mainly applied to Machine Tool, Electric Discharging Machine, Cutting Wire Machine, Plastics Injection Machine, Semi-conductor Equipment, Precision Orientation Equipment and other equipments and machines. Total relative lead variation Maximum width of variation over the travel length. Hence it is suitable for the machine with limit space for ballscrew installation.

The Procedure of Select Linear Guideway The specially catalogie pathway makes a ball circle diameter BCD into the return tube by tangency direction to match the direction of lead angle.

The Online Industrial Exhibition. It covers the whole production sequence, from receiving the order, designing, material preparation, machining, heat treating, grinding, omi, inspection, packaging and delivery. Hollow Cooling System of ballscrews A Purchase energy-saving products, improve the design of the energy performance.

Open the catalogue to page 5. To meet or exceed regulatory levels for emission and waste catslogue, within a labor-friendly work environment that utilizes the latest energy reduction technology to It is decided by both of the accuracy grade and effective thread length.


Application in high-lead and multiple thread grooves of ball screws. It is strictly required that there is at least one end of screw shaft with complete threads. We promise and are devoted to implement the following environmental and energy policies: Above are required for easy assembling the ballnut onto the screw shaft.

csrew Lead deviation in random mm. End cap series use the through hold which crosses both end of nut to consist a close loop. Lead Accuracy and Torque 2. End cap and wiper are one-piece make the shortest length of nut. Every department participates preserving our environment, energy awareness, and the prevention omi injuries, diseases and the reduction of energy consumption.

To protect the environment and personal safety by more actively promoting and implementing the ROHS green system, ESH and energy management systems.

Open the catalogue to page 2. Recent years, PMI Group places great emphasis in upgrading not only the manufacturing and quality of products but also the manpower. It is easy to transmit linear motion into rotation motion. 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.
