The Browning 407SMTP25B PJ0008 Shaft Mount Reducer delivers a precise 25:1 reduction in a rugged 407-series gearbox for solid‑shaft input and tapered‑bushing output. It uses a 2.1250 in input shaft, a cast‑iron housing, and standard double‑lip seals on plunge-ground shafts, with a tapered bushing output bore up to 4.4375 in. With an input speed of 1,750 rpm, the unit provides a nominal output of 70 rpm and a rated output torque of 900.34 in‑lbs at 1 HP; the maximum output RPM is listed as 80. The transmitter/gearbox weighs about 608 lb and measures 13.88 in long by 21.69 in wide by 27.80 in high, and it includes a torque arm for mounting. This AGMA‑standard shaft‑mount reducer is designed for screw‑conveyor drives and other material‑handling applications requiring a robust, taper‑bushed output in a Browning 407 series unit, identified by manufacturer part PJ0008 and model 407SMTP25B.
