Fabco-Air | SC, FML and FHL Series

Compact Cylinders That Keep Workpieces Secure

SC, FML and FHL swing clamps offer pneumatic or hydraulic operation, depending on the series, and several action types. Durable SC Series double-acting swing clamps provide a standard magnetic piston for position sensing plus workpiece protection features. The SC Series’ clamp arm has a built-in adjusting bolt, while the FML and FMH Series are available with either a single- or double-sided clamp arm.

The clamp arm extends in a straight line away from the workpiece to provide plenty of space to load or unload the part. The arm can rotate 90 degrees to full extension, and it swings 90 degrees when retracting. Customers can choose Model Code R for clockwise and Model Code L for counterclockwise rotation. When the clamp arm is positioned over the workpiece, it follows a straight-line path to apply the clamping force.

SC Series swing clamps operate with compressed air or petroleum-based hydraulic fluid, the FML Series uses compressed air and the FHL Series is a hydraulic model.
