Browning 315SMTP-25 Shaft Mount Speed Reducer

The Browning 315SMTP-25 Hydroil Shaft Mount Speed Reducer is a 25:1 gear reducer in the 315-size family designed for direct shaft mounting. This Hydroil-lubricated unit uses a 2.1250-inch input shaft and a tapered-bore output interface for secure connection to standard bushings. With a 25:1 reduction, it lowers motor speed while increasing output torque for compact drive trains where space is limited. The shaft-mount configuration enables direct coupling to the driven shaft, reducing alignment steps compared with belt-driven setups. As part of Browning's Torque-Taper Plus shaft-mount reducers, the SMTP25 model conforms to Browning's TorqTaper Plus design approach for power transmission in industrial applications. When selecting this reducer, ensure the driven equipment accepts a tapered-bore output via a compatible bushing and that the motor and load specifications align with the 315 size and 25:1 ratio.
