Two carriage assemblies here suit Masterglide™ sliding doors, both rated at 100kg. One is a heavy duty carriage, roller and anti-bounce guide supplied together; the other is a top-fix carriage and roller. Both also cover Tomma™ and Glidemaster™ rollers, which share the fitment. With only carriages listed, the message is clear enough — on a door of this weight it is the carriage that gives up first. The wheel wears, the bearing picks up grit, and the panel begins to bind, bounce in the track or drag on the floor. Before ordering, take the door out and check how the carriage fastens: a top-fix unit fixes up into the top of the panel, which is what separates the two parts here. Confirm the panel weight sits within the 100kg rating, and note whether the original had an anti-bounce guide fitted.
