Disc coupling Servoflex SFC DA2 C

doublealuminummotor

Description
The Double Flex DA2 version of the Servoflex SFC series is a cleanroom-compatible flexible coupling cleaned, assembled and packed for ISO class 6 environments. It provides high torsional stiffness and compensates axial, parallel and angular misalignment while maintaining low mass inertia due to lightweight high-strength aluminium alloy hubs.

Features

• Hubs made of high-strength aluminium alloy
• Cleanroom-compatible handling and surface treatment (ISO class 6)
• Ultra low inertia
• High torsional stiffness
• Rated torque examples: 5 to 100 Nm (varies by model)
