How to adjust the preload of the sliders of Curviline rails

Curviline rails are versatile and innovative curved linear rails with bearings, available in steel, hardened steel and stainless steel. The curve radii can be either constant or variable (even with straight sections) depending on the application. This characteristic and the nature of application make it essential to adjust and maintain the correct preload all along the rail.
See how in this video tutorial with our Techincal Director, Andrea Tosi.
