0.0/5 rating (0 votes)


R147 series linear shaft gear motor motors by level 2 or 3 class helical gear composition, RX using single stage drive, gear adopt high quality alloy forging steel material, the surface hardening treatment, after high-precision equipment shaping. Cast iron box ensure strength rigid, the precision machining, ensure the shape and position accuracy. Meet the bearing capacity of strong, long life, small volume, ratio, light weight, high efficiency, low noise of the superior performance.
