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.
Position repeatability ±0.02 mm.
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 25 mm to 55 mm. The Large size clamps bores 54 mm to 130 mm. The compact design of the smaller has a clamping force of 14 kN at 350 bar The larger models offer three clamping force ranges of 11.2, 17.5 and 28 kN at 350 bar, 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.
