Rollers are adjusted without clearance and effectively positioned for moment loads, therefore smooth movement is achieved even in cantilevered structure.
There are options as following. Lubrication unit suitable for dustproof and high-speed transfer, Connecting unit that can significantly reduce impact at rail joints, etc
In the case of end-face-to-end joints, even if the rails are aligned in the width and height directions and eliminate the clearance between rails, it can cause snagging at the joints by the slightest misalignment, therefore resulting in noise from impact and affecting the running life.
Connecting unit minimizes misalignment and can greatly reduce snagging at joints.
Please note the volume, and feel the difference.
