Gen2 units are direct replacements for original models

  • Changes to the housing fin design increases heat dissipation capacities, especially in the enclosed configuration of the UniModule.
  • Improved input to output axis design reduces vibration and improves noise and wear factors.
  • Use of custom designed mounting bolts allows for conduit box location directly on top of the unit.
  • Bolt hole patterns are re-positioned for ease of mounting.
  • Add-on enclosure cover kits allow for a unit to be upgraded to an enclosed unit in the field without replacing the clutch/brake. A cover plate bolts to both sides of the unit creating a completely enclosed brake package, which keeps contaminates out and wear particles in, for clean, quiet operation.
