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.
608 Bearing Reducer Sprue Set
A snap-off sprue of eight flanged reducers. Two 22 mm OD sleeves hold a 625 bearing (16.05 mm press bore) and two hold a 624 bearing (13.05 mm), each in an existing 608 pocket. Two 7.9 mm OD bushings with 3.4 mm bores and two with 4.4 mm bores let 3 mm or 4 mm shafts run through a 608's 8 mm bore. You can reuse 608 housings, wheels and pulleys for small gearmotor shafts without redesigning them. The whole frame is about 113 x 41 x 8.5 mm.
608 Two-Bolt Flange Bearing Block
A printed KFL08-style two-bolt flange bearing block. It press-fits a standard 608 bearing (8 x 22 x 7 mm) and bolts flat to a chassis plate or bulkhead with two M4 screws on 48 mm centres. The bearing supports the outboard end of an 8 mm drive shaft, axle or leadscrew. It is 63 x 30 x 13 mm, and a 15 mm lip under the bearing's outer race holds it in the pocket. 45° ribs brace the boss so radial shaft loads stay in the layer plane.
