NEW! I.D. Expansion Clamps
Double Acting
- Ideal for clamping in blind holes or bore holes.
- Save hours and fatigue by not manual clamping.
- Consistent clamping force without the use of a torque wrench.
- Range of expansion 0.010 to 0.015 depending upon size.
- Mandrel can be modified to fit application***.
- All cylinder pistons are chrome plated, hardened alloy steel.
* Holding forces are listed at 5000 PSI operating pressure. The minimum operating pressure is 500 PSI for D/A operation. The holding force is adjustable by varying the hydraulic pressure to the cylinder. To determine the approximate holding force for your application, divide the holding force shown above by 5000 PSI, and multiply the resultant by your system pressure in PSI to obtain the approximate holding force for your application. (Actual forces will vary slightly due to internal friction.)
** At full cylinder capacity, fastener life will be limited and fasteners should be considered service items. Fasteners should be replaced frequently when operating at full capacity to avoid plunger damage.
*** Mandrel diameter on clamp is shipped at max hole diameter. Mandrel can be machined down not to exceed min hole diameter to fit each application. Design should insure that mandrel does not expand more than 0.010″ for model 15-5206-00, 0.013″ for model 15-5210-00, and 0.015″ for models 15-5210-01, 15-5214-00, 15-5217-00, 15-5222-00.
**** Replacement Mandrel comes with pull bolt.

* Mandral diameter “C” is shipped at MAX condition. Diameter can be turned down to fit workpiece
bore. Diameter should not be machined down below “C MIN” dimension.
** Expand clamp approximately 0.002 to 0.003 over relaxed diameter and machine to fit workpiece bore.
bore. Diameter should not be machined down below “C MIN” dimension.
** Expand clamp approximately 0.002 to 0.003 over relaxed diameter and machine to fit workpiece bore.
For proper sealing, mating surface must be flat within 0.003 with a maximum 63 µin Ra surface finish.
