JFK recirculating ball linear guides
JFK linear guides
- High load capacity
- High precision
- Smooth and quiet motion
JFK ball recirculating linear guides are motion systems designed to provide precise, smooth, and reliable linear movement. Consisting of one or more ball recirculating carriages running on a hardened profiled rail, they ensure low friction and high performance even in high-speed and high-load applications.
The four-point angular contact design ensures optimal load distribution, high rigidity, and stability even under dynamic loads. Long service life with reduced wear over time, quiet and fast motion, dimensional interchangeability, and reduced maintenance make JFK ball recirculating linear guides the standard choice for the vast majority of linear motion applications.
Performances
Design and performance features
Four-point angular contact, recirculating balls, and hardened profiled rails for the optimal combination of precision, smooth motion, and load capacity.
Precision
High precision of movement and positioning The rolling contact of the balls and the four-point angular contact geometry ensure high motion accuracy, zero play, and consistent repeatability over time.
Motion
Smooth and quiet thanks to rolling contact Recirculating balls minimize friction, ensuring smooth and quiet motion even at high speeds. Uniform and controlled movement under all operating conditions.
Load
High load-bearing capacity in all directions The optimal load distribution across the four angular contact points ensures high rigidity and stability even under dynamic loads.
Service life
Long service life with reduced wear Rolling contact reduces component wear over time, ensuring dimensional interchangeability and reduced maintenance compared to sliding solutions.
Mounting
Ball recirculating linear guide installation
Installation requires the specified flatness and alignment tolerances of the rail and carriage mounting surfaces to ensure the accuracy specified by the selected class is maintained.
Installation Mounting
- Carriage installation with preloadThe carriage is installed with the preload specified for the application, checking for zero play and smooth, consistent movement along the entire travel.
