Japan Pascal Expansion clamp 7MPa Double acting Eccentric model CGU CGU-F21- CGU-F22E High Performacn Hydraulic Products Multi-purpose Applications

The Pascal CGT is a 7MPa double-acting hydraulic expansion clamp with a long neck design from PASCAL Japan. It uses a tapered spindle and jaw wedge mechanism for radial expansion clamping, specifically engineered for deep holes, stepped holes, blind holes and interference-prone internal bores. Ideal for CNC machines, automated production lines, rapid mold change and automotive part machining.

Main Models: CGU-F21- CGU-F22E

    Q: What’s the MOQ of customized tie-rod cylinder?

    A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.

    Q:What’s the lead time of customized tie-rod cylinder?

    A:  Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.

    Q: Are you the manufacturer of hydrualic cylinder?

    A: Sure, we are the manufacutuer and trading of hydraulic cylinder.

    Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?

    A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through

    a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.

    Q: I have a drawing, could you customized cylinder as my drawing?

    A: Sure. Show us the drawing, we will quote for you soonest.

    Q: Could you make the cylinder which is not on the above data sheet?

    A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.

    • Long neck design: Enables clamping in deep/stepped/blind holes where standard expanders cannot reach.
    • Double-acting hydraulic drive: Precise clamp/unclamp for high-frequency operation.
    • Mechanical self-locking: Built-in disc spring for safety against workpiece loosening during power/hydraulic failure.
    • High rigidity clamping: Lever amplification delivers high radial force in a compact package.
    • Tolerance compensation: ±1.0mm expansion margin for cast/machined hole variations.
    • Dust-proof sealing: Multi-layer seals resist chips and coolant in harsh environments.
    • Easy maintenance: Jaw seating surface regrindable (≤0.1mm) and flange field-replaceable.
    • Integrated sensing/air blow: Clamp/unclamp detection and air blow for automated integration.
    • Long service life: Disc springs withstand millions of cycles with minimal deformation.
    • Deep hole clamping: Bushings, sleeves, gear blanks, valve bodies on CNC lathes/machining centers.
    • Interference-prone bores: Clamping in stepped/blind holes with internal obstructions.
    • Automated production: Integrated with manipulators for unmanned workpiece handling.
    • Rapid mold change: High-precision clamping of mold bases/cavities with deep holes.
    • Automotive parts: Engine blocks, gearboxes, steering knuckles with high stability requirements.
