5mm Metal Hex Bore Gears


5mm Metal Hex Bore Gears are compatible with the REV DUO System and work with REV 5mm hex shafts in high-load applications. REV metal gears are NOT compatible with REV plastic gears.

All REV metal gears are narrower than plastic gears, allowing for compact drivetrains and gearboxes within the same 15mm width as our extrusion and punch tube. 6 different gear sizes available for a wide range of options.
