Shed Door 608 Track Roller And Bracket
A replacement sliding shed or barn door roller: a 40 mm V-groove wheel that takes a press-fit 608 bearing (8 x 22 x 7 mm), plus a 60 x 46 mm door bracket with an 8.3 mm bore for an 8 mm rod or M8 bolt axle. The bracket mounts with slotted #10 wood-screw holes that give 10 mm of height adjustment. Both pieces print as one plate joined by small snap-off tabs.
Surface-Mount 624 Screen Door Roller
This roller replaces a discontinued roller on a sliding patio or storm screen door. A 56 x 27 x 5 mm plate screws to the inside face of the bottom rail with two #6 screws. The screws sit in 12 mm vertical slots, so you set the door height when you tighten them. The wheel is a 624 bearing (4 x 13 x 5 mm) held by an M4 x 14 screw threaded into an M4 heat-set insert. The insert presses into a 5.5 mm bore from the back of the plate. The bearing sits on a raised land that touches only its inner race, and it hangs 1.5 mm below the bottom of the plate so it runs on the track rib.
Sliding Door Tandem Roller Carriage
A replacement tandem roller carriage for a sliding closet/wardrobe door, 70 x 30 x 13.6 mm, that runs on two standard 608 skate bearings (8 x 22 x 7 mm) spaced 38 mm apart on integral 7.7 mm stub axles with M3 retainer bolts. Four 4.5 mm M4 holes in two rows 8 mm apart let you set the door ride height when the original nylon wheels have collapsed and the part is no longer sold.
