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

  • Sudden, slam-type stalling should be avoided. Applications of this kind, which are beyond the expected normal performance of pneumatic power motors, will damage the power train due to the dynamic shock loads imposed.
