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.
