0.5 module GEARBOX kits 25:1 and 12.5:1 ratio with 1/8" input shaft
0.5 module teeth have load carrying capacity appropriate for O scale and larger model applications. The small worm diameter combined with the high quality gear surface provides high efficiency meaning smoother operation and greater load pulling capacity for a given motor output. For even greater capacity and smoother operation, ball-bearing (worm shaft) versions are available. These gearboxes can be used singly or paired for articulated locomotives (idler style cannot be combined with non-idler (direct) and must use matched ‘HiLo’ gearbox set). The low profile non-idler (single) is particularly useful when desirable to hide the driving mechanism in the locomotive frame, either diesel or steam type.
