H138-1C Pneumatic Zero Point Clamp (Long Type)

JIYAN H138-1C Pneumatic Single Hole Zero Point Clamp – Long Type

Specifications

Key Features

• Single pneumatic port activation – independent zero‑point clamping with simple on/off control

• High repeatability – ±0.005 mm (0.0002″) for precise and consistent pallet changes

• Long rectangular base – 170 × 140 mm footprint provides increased mounting stability

• Low profile design – only 53 mm height, preserves Z‑axis clearance for tall workpieces

• Heavy pull‑down & clamping force – 55 kN (12,364 lbf) pull‑down / 17 kN (3,822 lbf) clamping

• High max. air pressure – operates up to 1.2 MPa (174 psi) for demanding applications

• Hardened steel construction – wear‑resistant body for high‑duty production cycles

Application Scenarios

• Fixture plates and pallets – longer base distributes clamping load evenly across wider fixtures

• Vertical machining centers (VMCs) – low profile improves accessibility for manual loading

• Automated pallet systems – repeatable zero‑point locking for robotic work cells

• Tombstone fixtures for HMCs – multiple units mount securely on each tombstone face

• Heavy workpiece clamping – 55 kN pull‑down secures large or unbalanced parts

• 4th/5th axis applications – compact height fits tight rotary table envelopes

Why Choose JIYAN

• Stable rectangular footprint – resists rotation and torque better than square or round bases

• Low profile design – 53 mm height saves valuable Z‑axis stroke on CNC machines

• Precision ground locating surfaces – each unit verified for flatness and lock repeatability

• Pneumatic only – no hydraulic power unit needed, simplifies shop floor setup

• Custom mounting hole patterns – available upon request for non‑standard machine tables

• Hardened and ground body – maintains accuracy through millions of cycles
