Bore clamp with 3 points used for concentric positioning the ID of a bore, internal clamping expands radially to center the bore. Great for engine blocks! Capable of moving a part approximately 2.54 mm after the part is placed over the center mandrel. The clamping points retract for easy loading, then expand hydraulically to center the bore. Positional repeatability of +/- 0.02 mm May be manifold mounted as shown or purchase the optional Mounting Plate for bolt-down or access to porting when mounting. Fits bore sizes from 54 mm to 130 mm. Normally used with other clamps to secure the part. Requires the use of fixed stops and or additional clamps to resist direct rotational torque.
