SAE and DIN Overhung Load Adapters:

RMG offers quality overhung load adapters in standard, SAE A, SAE B, SAE C, SAE D and custom designed to meet your exact application requirements.

We have many successful years of field experience to insure our quality and reliability.

Furnished with pre-heat-treated 4140 shafting, these input shaft assemblies are primarily intended to:

  • Permit easy adaptation of standard electric motors to gear reducers and clutches which normally interface only with hydraulic motors.
  • Permit the adaptation of belts and pulleys (instead of direct “plug in” hydraulic motors).
  • Permit the adaptation of belts and pulleys coupling an electric motor to gear reducers for use with Variable Frequency Drives.

The use of belts and pulleys (on either hydraulic motors or electric motors) with gear reducers, torque Hubs or clutches can often solve space problems. Additionally, by being able to belt drive the transmission equipment, it is possible to enjoy a wider selection of reduction ratios, speed values, and service factors.

Non-Standard Overhung Load Adapters:

We can custom design and build overhung load adaptors to your production requirements. Most transmission equipment is installed with the axis horizontal. When this equipment is installed with the axis VERTICAL and the input shaft assembly ABOVE the gear reducer or clutch, special provisions must be made for lubrication. Contact RMG factory office for details.
