Twin-608 Compost Tumbler Drum Roller
A replacement drum roller for barrel-style compost tumblers. It has a 60 mm OD tread, is 32 mm wide, and has a 72 mm guide flange that keeps the drum from walking off the roller. Two press-fit 608 bearings (22 mm OD) ride on an 8 mm rod or M8 bolt axle, so it replaces plastic rollers that wear flat or crack. It is built with spokes and a drained web, so no solid slab soaks up water or compost.
