Ball and roller recirculating types for every precision and load capacity requirement
JFK linear guides enable highly precise linear motion with a very low coefficient of friction. They consist of ball or roller recirculating carriages (or blocks) that run on hardened profiled rails, providing long travel, zero play, and high positioning repeatability. The four-point angular contact design ensures optimal load distribution in all directions, providing high rigidity and positioning accuracy.
JFK Group offers ball recirculating linear guides (or linear slides) for high precision and smooth motion, and roller recirculating linear guides for maximum rigidity and load capacity in the most demanding applications. Both types offer long service life, quiet and fast motion, dimensional interchangeability, and reduced maintenance.

SELECTION GUIDE
Start by identifying the operating conditions
JFK linear guides cover a wide range of applications, from high-precision automation systems to heavy loads in industrial machinery. Start with the operating condition that best describes your application.
High precision and smooth operation
Ball recirculating linear guides for smooth, quiet, high-speed motion. The standard choice for the vast majority of linear motion applications.
High loads and maximum rigidity
Roller recirculating linear guides for maximum structural rigidity and load capacity. The ideal choice when ball recirculating guides are not sufficient for the loads and stresses involved.
Environments with dirt and contaminants
Both types are available with specific seals and protection systems for harsh environments. High-speed movements
Ball recirculating linear guides, thanks to their low rolling friction, are best suited for high-speed applications.
