There are 4 types of speed reducers and 3 types of motors available in this range, most varying in performance and dimensions.
Four sizes of CHPC pre-stage gears are available to pair with the gears; these are also constructed in aluminium and are painted just like the worm gears
Gears that are supplied with mounting flanges should be assembled with motors whose shaft and flange tolerances match a “normal class” of quality in order to avoid vibration and forcing of the insight bearing.
