LFR profiled track rollers without filling slots are used to guide the carriages and support the forces. These double row angular contact ball bearings have an outer ring with a gothic arch profile raceway, are sealed on both sides and are greased for life. They can support axial loads from both sides and high radial forces due to the thick-walled outer ring. Two points contact between gothic arch groove profile and track. Accuracy class P6 ISO492/DIN620. Radial and axial runount is below 0.02mm. Radial bearing clearance approaching class CN.
