features
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
Large oil reservoir provides efficient heat dissipation and lubrication for longer life
Housing is straddle milled top and bottom for precise alignment
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
If the bearing is to be shrink fitted, care is required to prevent damage to the bearing. Cool the bearing gradually. Do not cool the bearing below -20 °F (-28 °C). Dry ice or other super cool materials should not be used. Pounding the bearing in a chille
