• Torsiflex-i couplings consist of 2 hubs and a factory assembled transmission unit. 
• Installation involves fitting the hubs to the machinery shaft ends, introducing the transmission unit, then securing with the attachment screws 
• MAXIMUM SPEEDS shown are for standard materials. When higher speeds are required please consult Ameridrives Couplings 
• PEAK TORQUE of 1.75 and MOMENTARY TORQUE of 2.7 times the stated ratings are accepted 
• SPARK FREE overload protection is provided as a standard feature on all Torsiflex-i couplings, making them suitable for GAS ZONE environments
• STANDARD COUPLINGS are designed for general purpose applications and are suitable for the majority of process pump, fan, and compressors applications
• SPECIAL COUPLING versions available include: 
  • Torque overload protection 
  • Limited end float
  • Electrical Insulation
  • Bolted adapters suitable for high cyclic torques
