HAIMER Shrink Fit vs Hydraulic Chucks
Shrink-fit and hydraulic holders both target precise concentric clamping but use very different assembly methods. Shrink fit thermally expands the holder bore; hydraulic chucks contract a sleeve through internal pressure.
Side-by-side comparison
| Category | HAIMER Shrink Fit | Hydraulic Chucks |
|---|---|---|
| Assembly method | Induction heating expands the bore for tool insertion, followed by controlled cooling. | A side screw actuates the internal hydraulic chamber without heating. |
| Holder profile | Slim, rigid profiles can improve access in molds, dies and five-axis work. | The hydraulic mechanism generally requires a larger body but provides damping. |
| Infrastructure | Requires compatible heating and cooling equipment plus thermal-process discipline. | Requires no external assembly machine, but seals, sleeves and actuation limits must be maintained. |
Best fit by application
HAIMER Shrink Fit
- Choose shrink fit for slim access, rigidity and high-speed assemblies where the thermal workflow is supported.
Hydraulic Chucks
- Choose hydraulic chucks where damping and quick tool changes without heat are more important.
Selection notes
Shrink fit favors rigidity and access; hydraulic clamping favors damping and convenient assembly.
Variables to validate
- Compare actual holder gauge length, balance, runout, torque and tool-shank tolerance.
