features
Large oil reservoir provides efficient heat dissipation and lubrication for longer life
Housing is straddle milled top and bottom for precise alignment
Rugged housing fabricated of fine-grained cast iron for maximum strength and greater precision during worm and gear alignment
Bronze worm gear is straddle mounted between heavy-duty tapered roller bearings to increase thrust and load capacities on size 713 to 760
High strength steel output shaft ensures capacity for high torque
Pipe plugs allow easy fill, level and drain in any mounting position
Super finished oil seal diameters on both input and output shafts extend seal life
caution
All conveyor troughs should have some type of cover not only to keep material inside the trough and to protect material in the trough from outside elements, but also as a safety precaution.
