Flexible coupling Servoflex SFC SA2 C series

for motorsfor machinesfor servo motors

Product overview
The Single Flex coupling Servoflex SFC SA2 C (clean room version) from Miki Pulley is cleaned, assembled (ISO class 6) and packed for cleanroom use. It combines very high torsional stiffness with compensation capability for axial, angular and parallel misalignments while offering ultra-low inertia due to a high-strength aluminium alloy construction.

Main features

• Hubs made from high-strength aluminum alloy
• Clean room suitable surface treatment (ISO class 6)
• Ultra low inertia
• High torsional stiffness
• Rated torque range example shown on page: 5 to 100 Nm (varies by model)
