Manually-controlled clamping device QLSWC series

cam-operatedworkpiececorrosion-resistant

Description
Compact one-touch cam-action swing clamps designed to swing clear for part loading and then clamp directly downward to apply positive downward pressure. The arm swings fully out of the work area for fast loading/unloading, making these clamps suitable for repetitive production clamping. Supplied with a reversible contact bolt to accommodate finished or rough surfaces. Top-mounted installation using two mounting holes. Parts with suffix R clamp clockwise (CW); suffix L clamp counterclockwise (CCW). Components: body, handle and spindle = 1045 alloy steel; clamp arm and cam shaft = 4140 alloy steel. Heat treated and available with electroless nickel plating for improved corrosion and wear resistance in demanding environments.

Characteristics / Technical specifications

• Function: One-touch cam-action swing clamp for direct downward clamping and quick swing-out for part loading/unloading.
• Mounting: Top mount using two mounting holes.
• Contact bolt: Reversible to suit finished or rough surfaces.
• Clamping direction: Part numbers ending in R = clockwise (CW); ending in L = counterclockwise (CCW).
• Materials: Body, handle and spindle = 1045 alloy steel; clamp arm and cam shaft = 4140 alloy steel.
• Treatment & finish: Parts heat treated; electroless nickel plating (suffix -NP) for enhanced corrosion and wear resistance.
• Available thread sizes: M4x0.70, M5x0.80, M8x1.25, M10x1.50.
• Typical clamping forces (approx.): 180, 337, 472, 629 lbs depending on model.
• Typical strokes: Clamping stroke 0.8"–1.5"; overall stroke 1.2"–2.3" (model-dependent).
• Application: Designed for repetitive clamping tasks in demanding industrial environments.
