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
Periodic inspection is required to determine if the unit is in proper working order by inspecting and replacing the urethane seal, inspecting to see if material buildup has occurred and ensuring proper adjustment and tightness of all adjustable bolts.
The Guardian™ is designed to help minimize the potential for danger but cannot guarantee protection in all situations or applications.
