features

  • 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
  • Large oil reservoir provides efficient heat dissipation and lubrication for longer life

caution

  • Drives used in a vertical mounting application may require additional pipe plugs and/or grease fittings for proper lubrication and are considered special.
  • High loads, high ambient or operating temperatures, and unusually contaminated atmospheres will require more frequent relubrication.
