Use: for construction of sliding elements in combination with the guide Part 2056.
Material aluminium runner, 2 concentric grooved rollers and 1 eccentric grooved roller in steel, 3 M6 washers and 3 M6 nuts in galvanised steel.
Characteristics: The central roller with cam allows offsetting any clearance between the seat and the side rollers (in vertical assembly, the 2 side rollers bear the load, while the central one is only used to recover the clearance).
Warnings: should be preferentially used in the place of runners with polyamide bearings Part 2054 for construction of large and heavy doors (glass buffer) and for applications that require horizontal fitting (e.g. sliding tunnels). The runners must always be used in pairs.
