The C-rail, bearing set 8 D14 1R is used as a bearing set for self-assembly of C-rail, bearing units. To attach the bearing sets to the C-rail, slide profile 8, countersunk holes for the fixing screws must be drilled 64.0 mm apart. The position of the holes is marked by a scribed line in the slide profile. In general, C-rail systems are variable and safe track roller guides and are designed in particular for the assembly of lifting and sliding doors. The pre-assembled track rollers are durable and maintenance-free. The C-rail bearing set 8 D14 1R can be subjected to a maximum tensile load of Fmax = 750 N.
