Manually-controlled clamp QLRC-08R

workpiecesteelhorizontal

These thrust clamps feature a clamping body and a clamping bar used together for a wide range of workholding solutions. To clamp, simply push the bar through the center of the clamping body until contact is made with the workpiece. Final clamping is achieved by turning the handle which extends and clamps the bar for secure workholding. Releasing the handle allows the clamping bar to be retracted for workpiece removal. The long clamping bar projection range allows for clamping recessed or hard to access parts. The clamping bar has a tapped end so it can fit with a custom tip. The clamping bar can be cut shorter to the desired lengths. (If the user is making a custom clamping bar, it is recommended the outside diameter is finished to an h9 or better tolerance to insure proper fit.) Mounts from the top with two mounting holes. Part numbers ending with R have a clockwise clamping direction and part numbers ending in L have a counter clockwise clamping direction. When the reaction force exceeds the stated clamping force, the clamp will release. The clamping body and lever arm are made from 1045 alloy steel. The internal cam is made from hardened 4115 alloy steel. Black oxide finish. The handle is black plastic. The clamp body and clamp bar are sold separately.
