JFK linear motion systems
Precision and reliability for every application
Guides, screws, and bushings for precise linear motion in every industrial application.
JFK linear motion systems are high-performance solutions for achieving highly precise linear motion with very low friction. These systems are ideal for industrial applications requiring support for loads and moments in all directions, while ensuring long travel, zero play, and repeatable positioning.
JFK Group offers a complete range of ball and roller recirculating linear guides, ball screws, and bushings, both ball recirculating and plain, to meet every application requirement, from precision systems to high-load applications. All products guarantee verified quality, with availability and technical support ensured at every stage of the project.

SELECTION GUIDE
Things to consider before making a choice
Selecting the most suitable linear motion system requires evaluating several technical parameters: applied load, service life, space requirements, speed, duty cycle, accuracy, and rigidity.
Solutions
Find the right solution for your application
01
When to choose ball recirculating linear guides?
When high positioning accuracy is required, typically in CNC machines, robotics, automation systems, and packaging machinery. Ball recirculating linear guides provide smooth, quiet, and precise motion, making them the standard choice for the vast majority of linear motion applications on rails.
Suitable product families
02
When to choose roller recirculating linear guides?
When very high loads and high rigidity are required, for example in presses, heavy-duty CNC machining centers, and high-capacity systems. Roller recirculating linear guides provide maximum rigidity and load capacity when ball guides are not sufficient to withstand the operating loads.
Suitable product families
03
When to choose ball screws?
When rotary motion needs to be converted into linear motion, as in CNC machines, robotics, and positioning systems. Ball screws convert rotary motion with high efficiency and precision, with adjustable preload to eliminate play.
Suitable product families
04
When to choose ball recirculating or plain bushings?
When linear motion on cylindrical shafts is required, in machine tools, automation systems, and applications involving combined movements. Ball bushings deliver maximum performance on hardened shafts, while plain bushings are suitable for unhardened shafts or for applications requiring combined linear and rotational motion.
