H g shah & company, offers hitcon shaft-mounted speed reducers, which are very convenient method of reducing speed, since these are mounted directly on the driven shaft instead of requiring foundations of their own. These speed reducers eliminate the use of one and sometimes two flexible couplings and external belt take-up arrangement. A wide choice of final driven speed can be determined by the use of an appropriate input v belt drive. The units normally are oil lubricated, but are equally suitable for lubrication for life greases, they consist of hardened precision machined alloy steel helical gears mounted on micro finish shafts supported on long life precision bearings with the capacity of handle maximum loading. The two-piece close grain el housing provides sturdy and insures permanent accurate alignment of all components.
