LEESON OS300 Series Off-Set Shaft Gearmotor performance matched for continuous duty throughout the speed range. Constant torque 60:1 speed range when powered by a full-wave unfiltered SCR-type adjustable speed control having form factor up to 1.05.

Features:

  • 5/8" Keyed output shaft
  • Precision machined in-line steel gears
  • First stage steel helical gear followed by spur-type gears
  • Lubrication is permanent semi-fluid grease, reducing possibility of leakage
  • Output shafts have needle bearings for high load capacities
  • Shafts are hardened steel
  • Conduit box is NOT included (see related products)

Application Notes:

  • Placing the gearmotor with the motor below the gearbox should be avoided to prevent leakage of lubricant into the motor should the motor shaft seal fail
  • Motor’s stall torque could exceed recommended full load torques. A current limiting device such as an
    SCR control should be used to prevent damage. This issue is even more critical for low voltage motors, typically no controller is used since motor is connected directly to a battery, so some type of current limit or fusing should be considered
  • Overhung load capacities shown are at center of output shaft
