Carr Lane CLR-1574-812 | 55.00mm Diameter x M12 x 14mm Thread 6.00mm Stroke 5500 lbs Force Threaded-Body Clamping Module with Mounting Block

Product Information

7250 psi max Single and Double Acting These pull clamps can be used to make a combination locator and clamp by adding a custom locating pin. The 55mm counterbored hole is a reference diameter to accept custom locators. The plunger has an extended key at the bottom to act as an anti-rotation device, for applications where plunger orientation is important to provide machining clearance. These versatile clamping modules provide considerable force in a small size, and can be placed very close together. Ordering the Threaded-Body Clamping Module in this mounting block allows using standard fittings instead of manifold mounting, and requires much less machining to install. Available in one size, which can be used as single acting or double acting. Pull force at 7250 psi:          5500 Lbs

Application Information

The plunger has an extended key at the bottom to act as an anti-rotation device, for applications where plunger orientation is important to provide machining clearance.

Clamping Action

Applying fluid pressure pushes the piston down, pulling down a drawbar inserted in the center hole. Spring return (single acting), with the option to add a return pressure line to use as double acting.

Mounting & Fluid Supply

Locate each clamping module in exact position using the 55mm counterbored hole as a reference diameter. Once in proper location, fasten clamping module to fixture with four socket-head cap screws. Two 1/4" BSPP ports. Do not use NPT fittings.

Clamping with a C Washer

Clamping can be accomplished using a drawbar and C Washer. This method provides maximum clamping force, but has some disadvantages. The C Washer is a loose part that must be handled each time a workpiece is loaded. Also, the C Washer can interfere with machining operations on the top side of the workpiece.

Clamping with a Polyurethane Spring

Clamping can also be accomplished using a drawbar to compress a polyurethane spring that is slightly smaller than the inside diameter, to apply clamping force from the inside. Note: this method still requires a locating pin to provide location for the inside diameter. Clamping force depends entirely on the spring material, with the plunger going through its full 6mm stroke.
