Pneumatic Push-Rod Clamp 621 — Horizontal-foot pneumatic clamping device, 4.5 kN thrust (Kukamet)

The Pneumatic Push-Rod Clamp 621 is a horizontal-foot clamping device designed for automated workholding and production fixtures in machine shops and assembly lines.

• 4,500 N maximum thrust force
• 7,200 N maximum holding force
• Zinc-plated body with horizontal foot mount

Consistent high-force clamping for reliable production

The unit delivers a 4,500 N maximum thrust and a 7,200 N holding force, engineered for repeatable workholding under cycle stress. This force profile reduces part movement during machining and assembly, improving process stability and reducing rework rates. The compact piston design with an 18 mm diameter transmits force efficiently while keeping the actuator stroke suitable for common fixture geometries, allowing reliable clamping in short cycle times without large spatial demands.

Compact, corrosion-resistant construction for durable fixtures

A zinc-plated housing provides enhanced resistance against corrosion in workshop environments, ensuring the clamp maintains dimensional integrity over repeated use. At approximately 2.26 kg, the device combines lightweight installation with robust mechanical properties, simplifying fixture design and reducing inertia on moving assemblies. The horizontal foot mounting facilitates straightforward attachment to plates or subframes, making it suitable for jigs, modular tooling and automated stations where footprint and longevity matter.

Simple mechanical integration into automated systems

The actuator’s geometry and mounting style support direct integration into pneumatic circuits and fixture plates. The 18 mm piston diameter is compatible with standard valve sizing, enabling predictable air consumption and control behaviour when paired with existing plant pneumatics. Engineers benefit from clear, measurable parameters for cycle planning and safety margins, which simplifies engineering documentation and accelerates commissioning.

Designed for dependable production and clear specification

With standard classification data included, the clamp supports planning and procurement without ambiguity. The device’s measurable characteristics provide the basis for engineering decisions: force calculations, fixture stiffness and component life estimations. Where corrosion resistance, compact mounting and consistent clamp force are required, this model offers a practical balance between performance and simplicity — a solid choice for repetitive manufacturing tasks and fixture retrofits.

FAQ

What maximum thrust and holding forces does this clamp provide?
The clamp offers a maximum thrust of 4,500 N and a holding force up to 7,200 N, suitable for medium-duty production fixtures and automated workholding.

Is the clamp suitable for corrosive workshop environments?
The zinc-plated housing gives the unit increased corrosion resistance, making the clamp appropriate for standard workshop atmospheres and manufacturing cells.

How is the clamp mounted to a fixture plate?
Mounting is via a horizontal foot, allowing direct bolting to plates or subframes; the horizontal-foot design supports compact fixture arrangements.

Which piston diameter is used and why does it matter?
The actuator uses an 18 mm piston diameter; this dimension informs valve sizing and expected air consumption, which helps engineers size pneumatic controls for consistent cycle performance.

Can the clamp be integrated into existing pneumatic systems without modification?
Yes, the clamp’s standard pneumatic characteristics are compatible with common valves and supply pressures, enabling integration into existing circuits with standard components.
