<p>The suspension roller (1) for a sliding door has a central groove (10) forming, on either side, two lateral outwards inclined sides (12). These inclined sides are supported against the side edges of ramps inserted in the suspension rail. The side edges constitute a rolling track for the roller sides. These sides curve outwards to enable the rollers to slide toward the bottom of the ramps. The roller central groove is enclosed by two small planes (11) following the outwards inclined sides.</p> |
