Centering Clamp, Small Bore, 2 Point Contact (PDF 332.00 KB)

Specifications

Centering Clamp, Small Bore, 2 Point Contact

Double Acting

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. This allows for minimal part variance of the second bore in a third clocking axis, while centralizing both.
Bore clamp with 2 point used for concentric positioning of a 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, then expand hydraulically to center the bore.
Positional repeatability of ±.001”.
Compact design keeps the large capacity working cylinder out of the way and below the part.
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 1-2.17”.
Can be used to center a slot, keyway 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.
