JFK ball screws

JFK linear motion systems

High mechanical efficiency and positioning accuracy, with adjustable preload to suit any requirement for rigidity and repeatability

JFK ball screws are an advanced solution for motion transmission, ideal for applications requiring high precision, efficiency, and reliability. Thanks to the balls circulating between the screw and nut, a ball screw converts rotary motion into linear motion with extremely low friction.

High mechanical efficiency reduces friction losses, while high precision and repeatability make ball screws ideal for positioning applications. Their long service life is ensured by reduced component wear. Adjustable preload eliminates play and increases system rigidity. Ball screws are widely used in CNC machines, industrial automation systems, robotics, and packaging machinery.

Versions

A single product type, configurable for preload and precision

JFK ball screws are available as a single product type, with no separate sub-types. The ground screw and nut with recirculating balls are differentiated by preload class, from zero to high preload, and by accuracy class, allowing rigidity and accuracy to be tailored to each application. The optimal configuration (lead, diameter, and preload) is determined based on the required load, speed, and accuracy. The JFK technical team is available to support application-specific sizing.
