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
Product Introduction: Pascal CGT (7MPa Double‑acting Hydraulic Expansion Clamp, Long Neck Model)

A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
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.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
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.
A: Sure. Show us the drawing, we will quote for you soonest.
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.
