Small Bore 3 Point Contact Center Clamps (PDF 482.00 KB)

Specifications

Centering Clamp, Small Bore, 3 Point Contact

Double Acting

Bore clamp with 3 points for concentric positioning of the ID of a bore, internal clamping expands radially to center the bore.
The clamping points retract for easy loading.
Capable of moving a part approximately 2.54 mm after the part is placed over the center mandrel.
Positional repeatability of +/- 0.02.
Compact design keeps the cylinder out of the way and below the part.
May be manifold mounted as shown or purchase the optional Mounting Plate for bolt-down access to porting when mounting.
Fits bore sizes from 25 mm to 55 mm.
