TorqTaper Plus
Browning® TorqTaper Plus® shaft mounted reducer gearboxes are designed with a systematic approach for maximum life in rugged industrial environments. The patented design that allows ease of installation and removal. The TorqTaper Plus bushing can be installed on either the inboard or outboard side of size 107 through 315 reducers. The system also utilizes a bronze stabilizer ring on the opposite end of the bushing. The stabilizer ring helps minimize fretting corrosion which makes removal of the reducer easier.

Heavy-Duty Components
The Browning TorqTaper Plus speed reducer is built around AGMA class 12 gearing and employs tapered roller bearings on all shafts.
Enhanced Sealing System
Since contaminants are constantly on the attack against oil seals and lubricants, the TorqTaper Plus reducer is protected by a patented triple seal system that extends the life of the bearings and gears.
Mounting System
The TorqTaper Plus mounting system is based on a single tapered bushing for straightforward, error-free installation and removal. This system requires no special tools and is designed for simplicity in limited work spaces. These design features work in concert to help provide you with maximum uptime and minimal maintenance.
Innovative Input Configurations
TorqTaper Plus shaft mounted speed reducers are also available with c-face and hydraulic input configurations for use in a variety of applications.
AGMA Class 12 Gearing and Tapered Roller Bearings
Helical gearing is cut to AGMA Class 12 and keyed to all shafts. All shafts utilized tapered roller bearings.
Single Bushing System
TorqTaper Plus reducers feature a patented, reversible, single bushing system that easily installs from either side of the reducer. The bushing system includes an optional end cap cover and stabilizer ring to reduce shaft mount wobble, prolonging gearbox life.
