Vektek Inch Hydraulic Clamping Catalog

Special Use Clamps

Centering Clamp, Large Bore – 2 Point Contact

Double Acting

Clamping Range Ø

 Often used when trying to locate using 2 bores on the same part. Use the 3 point Centering Clamp for the first bore, the 2 point unit for the second bore often in an engine block. This allows for minimal part variance of the second bore in a third “clocking” axis, while centralizing both. Functioning similar to using round and diamond locators.  Bore clamp with 2 points used for concentric positioning of a bore, internal clamping expands radially to center the bore.  Capable of moving a part approximately 0.100” after the part is placed over the center mandrel.  The clamping points retract for easy loading.  Repeatability of ±.001”.

 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 2.13” to 5.12”.  Can be used to center a slot, cavity, or other non-round feature, but normally the 2nd bore in 1 part. Requires the use of fixed stops and or additional clamps to resist direct rotational torque.
