features
- Large oil reservoir provides efficient heat dissipation and lubrication for longer life
- Housing is straddle milled top and bottom for precise alignment
- Internal baffles ensure positive, leak-free venting
- 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
- 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
