Helical gear tooth design and twin tapered bushings make these reducers the optimal gearboxes for conveyors, mixers and packing machines. Corrosion resistant, precision machined, ductile iron cast housings. Ribbed housing construction provides strong bearings and gearing support. Oil channeled to all bearings for superior lubrication. Double lip seals retain oil while locking out dirt. Reducer mounts directly on driven shaft, eliminating the need for coupling or chain drive, sliding motor base and support structure and avoiding all alignment problems.
