Ball guideways use point contact between steel balls and raceways, delivering low friction and rapid response—ideal for light to medium loads at high speeds. Roller guideways rely on line contact between cylindrical rollers and raceways, significantly boosting load capacity and rigidity—perfect for heavy cutting or long-travel applications. In short: choose ball for speed and energy savings, choose roller for load and precision.

JSWAY turns both options into plug-and-play modules. Light-duty Swiss-type lathes and gang-tool lathes leave the factory with ball guideways for balanced cycle time and cost; heavy-duty turn-mill centers are upgraded to roller guideways to maintain micron accuracy under heavy cuts. Even better, the same slide can later be switched between ball and roller with a simple component swap—no downtime, no waste.
