Product Description
Introduction to Rolled Ballscrews
The production of the PMI rolled ballscrews has adopted a manufacturing process and equipment unlike other manufacturers. Combining advanced skills and the Bad Düben digital electric screw thread rolling machine, we adhere to a strict quality control policy at every stage of production, from the selection of ballscrew material and rolled processing to induction hardening heat treatment and post production. We are committed to providing clients with products of the best quality.
The combination of rolled ballscrews and ground nuts has replaced the traditional ACME screws and trapezoidal screws. This makes for a smoother operation while lowering friction and backlash. Moreover, the new technology has the advantage of faster production speed and lower prices.

Features of Rolled Ballscrews
High Precision Rolled Nuts
The manufacturing process of rolled and ground nut is the same . After surface hardening treatment, it is finely ground with an internal thread grinder to maintain durability and smooth movement.
Nuts are Interchangeable
When the ballscrew and nut are not preloaded, the ballscrew of the same specification can be replaced with different types of nuts within the maximum allowable axial backlash.
