Characteristics of JAC-Flex Coupling

• Rapid and easy assembly/disassembly. Element consists of two halves split longitudinally.

• Protects equipment. Super flexible urethane element is capable of up to 40 angular and 4.7mm  parallel misalignment Longer system life.

• Lower weight and inertia.
  Less transmission of vibration Longer Life for motor and pump bearings.

• Compact. Connected equipment can be moved closer. No need to provide space to back out coupling bdts.

• Safe. Non-sparking, Reduces risk of fire." No lubrication.

5 times Continuous Torque test guarantee the flexibility of coupling

Design Characteristics are validated with torsional test : Torsional Stiffness, Axial Stiffness, Radial Stiffness

Composition of JAC-Flex Coupling

JAC Flex coupling is composed of 2 split-in-half elastic element and self-locking bolts.
It is easy to replace elastic element without disassembly of hubs or connecting elements

	Mount hubs on shafts.
	Place one elastic element on hub andposition bolts on hub and elastic element.
	Place another elastic element on hub. Tighten the bolts with assigned torque.

Tightening Torque of bolts

Selection of Coupling Size

1) Determine service factor considering driver and driven equipment referring to load classification and Safety Factor Table.

2) Multiply service factor to normal operating power. This will provide a Design Power for the purpose of coupling selection

3) Use the power and the operating speed to select the coupling size from the upper chart.

4) Or multiply operating torque by service factor and select a coupling from the torque capacity chart

5) After selection as mentioned above, we confirm the satisfying size as compared with the maximum bore diameter.

Misalignment Guideline of JAC-Flex Coupling

Maximum of Each misalignment cannot be experienced by the coupling simultaneously. eachmisalignment shall be below the line. bore diameter.
