Selection Suggestions

  • Double Roller Chain Couplers have  a torque capacity which is more than the torque normally transmitted by the shafting that will fit each coupler bore range.
  • Select the smallest coupler size which will accommodate both of your shafts.
  • For reversing operations, shock or pulsating loads, or other severe operating conditions, select the next larger coupler size.
