Special Use Clamps
Centering Clamps
Small Bore and Large Bore Centering Clamps with 2 or 3 centering posts Centering Clamps are essentially a bore clamp used for locating a part. They are capable of centering parts using a rough or finished bored hole. Internal clamping posts expands radially to the bore diameter of the workpiece to be clamped. If 1 clamp is used, most applications call for a 3 point clamp to center the bore, if a second bore clamp is to be used, a 2 point clamp provides centering and clocking for the secondary bore.
A simple cavity design makes machining for manifold mounting simple. Hydraulic fluid is supplied through manifold channels drilled in the fixture body. Alternatively if surface mounted, hydraulic fluid may be supplied through a connection plate. Connection plates are available for either pipe connections or bolt down O-ring manifold mounting. Note: Centering Clamps are not suitable for use on lathes or without additional clamps for holding against rotational forces. Be sure that your bore will not be damaged by contact from the posts which contact the part.

We offer two styles of Centering Clamps, with either 2 or 3 clamping points, in Small and Large Bore sizes. The Small size centers bores .98” to 2.17”. The Large size clamps bores 2.13” to 5.12.” The compact design of the smaller has a clamping force of 3,150 lb at 5,000 psi. The larger models offer three clamping force ranges of 2,520, 3,930 and 6,300 lb at 5,000 psi, enough to position even heavy parts. All models are double acting. Which means the cylinder is actuated hydraulically in both directions. All components are made from high-grade case-hardened steel.
