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
Ideal for use with filters and lubricators
Suitable for use in normal industrial environments, but should not be located in areas where they could be subjected to direct sunlight, an impact blow or temperatures outside of the rated range
Some chemicals can cause damage
Polycarbonate bowls should not be exposed to chlorinated hydro-carbons, ketones, esters and certain alcohols
Cannot be used in air systems where compressors are lubricated with fire-resistant fluids, such as phosphate ester and di-ester types
Polycarbonate bowls, being transparent and tough, are ideal for use with filters and lubricators. They are suitable for use in normal industrial environments, but should not be located in areas where they could be subjected to direct sunlight, an impact
