Key Features

• 2-in-1 integrated design – two zero point clamps built into one long baseplate

• Ultra‑low profile – only 53 mm height, saves valuable Z‑axis clearance on CNC machines

• Long span – 450 mm length accommodates large pallets and fixture plates

• Large through‑holes – Ø138 mm center opening per clamp for pass‑through coolant, air, or cables

• High repeatability – ±0.005 mm (0.0002″) per clamp for precise pallet registration

• Total pull‑down force – 110 kN (24,728 lbf) combined for heavy workpiece security

• High max. air pressure – 1.2 MPa (174 psi) for demanding production environments

• Rigid steel body – hardened and precision‑ground for high‑cycle durability

• Wide footprint – 450×180 mm base resists tipping and torque

Application Scenarios

• Large CNC pallet systems – 450 mm span supports oversize fixture plates without flex

• 5‑axis machining centers – ultra‑low 53 mm profile maximizes Z‑axis travel for tall parts

• Automated work cells – dual registration points ensure robotic pallet loading accuracy

• Horizontal machining centers (HMCs) – mount directly on machine pallets for quick changeover

• Long workpiece clamping – two widely spaced clamps prevent part tilting on extended parts

• High‑speed machining – 110 kN total pull‑down force eliminates vibration in aggressive cuts

• Through‑coolant applications – Ø138 mm openings allow coolant to pass through fixture plates

Why Choose JIYAN

• True 2‑in‑1 integration – no alignment or spacing errors between separate single clamps

• Lowest profile available – 53 mm height keeps pallet surface close to machine table

• Large through‑hole advantage – Ø138 openings per clamp allow pass‑through of utilities

• Pre‑set clamp spacing – factory‑set positions eliminate measurement and setup time

• Precision ground reference surfaces – each unit verified for flatness and parallelism

• Pneumatic only – no hydraulic power unit required, simplifies installation

• Ready for automation – consistent zero‑point locking for robot‑tended cells

• Custom hole patterns – available upon request for specific machine tables
