Twin-608 V-Groove Gate Track Roller
A 64 mm OD, 30 mm wide rolling-gate wheel with a 90° V-groove (12 mm deep) that rides an inverted angle-iron track. It has a root relief slot so the rounded heel of the angle never bottoms out, and two press-fit 608 bearing pockets (22.05 mm) that take an 8 mm / 5/16 in axle bolt. It replaces the grooved wheel on a sagging sliding chain-link or wood gate, which stores usually only sell as a full roller assembly.
24T Winch Worm Wheel
A module 1.5, 30° pressure angle, 24-tooth worm wheel for the 'N20 Self-Locking Worm-Drive Winch' kit. It has a 39 mm OD, a 10 mm face and a 16 x 10 mm hub, with an 11 mm shoulder that bears on the 608 inner race. The 8.3 mm bore slip-fits the 8 mm steel axle, and an M3x8 grub screw with a captured M3 nut locks it. Three M3x16 screws on a 22 mm PCD bolt it to the line drum's heat-set inserts.
