Pneumatic clamp 681-8 — Horizontal-base clamp with pneumatic cylinder by Kukamet

The pneumatic clamp 681-8 is a horizontal-base industrial clamp designed for 90° workholding tasks, offering high holding capacity and pneumatic actuation for rapid, repeatable clamping in production environments

• Pneumatic cylinder actuation
• Horizontal base mount
• Holding force 30,000 N
• Galvanised steel corrosion resistance

Reliable hold for serial production and safety-critical fixtures

The unit delivers a holding force of 30,000 N combined with a maximum pressing force of 6,500 N, giving a measurable safety margin for many clamping tasks in metalworking and assembly. These numeric values translate directly into lower slippage risk and improved process stability, which helps reduce rework and scrap rates. Where consistent repeatability matters, the mechanical design ensures every cycle applies the same clamping effort, aiding quality assurance and predictable throughput in production lines.

Faster cycles through pneumatic actuation and simple integration

Equipped with a pneumatic cylinder, the clamp converts compressed air into reliable clamping movement, shortening cycle times compared with manual or mechanically driven options. The horizontal base configuration simplifies mounting to fixture plates or machine tables and supports compact station layout. At approximately 20.475 kg, the unit is robust enough for industrial use yet manageable for integration into jigs and automated cells. Pneumatic operation reduces operator effort and supports automation, resulting in measurable efficiency gains on the shop floor.

Durable construction and low-maintenance operation for long service life

Constructed from galvanised steel, the clamp resists corrosion in typical workshop atmospheres and demands minimal surface care. The lever-style concept translated into a pneumatically driven mechanism combines proven mechanical simplicity with modern actuation, lowering service needs. Routine inspection of seals and a light lubrication schedule for pivot points are usually sufficient to maintain performance over time. Supplied as an industrial-grade component, the unit is suitable for demanding environments where uptime and consistent clamping are priorities.

FAQ

Is the clamp suitable for heavy-duty workshop fixtures?
Yes. The pneumatic clamp 681-8 provides a holding force of 30,000 N and a pressing force of 6,500 N, making it suitable for demanding fixture applications in metalworking and assembly.

How is the unit mounted to a fixture or machine table?
The clamp is mounted via a horizontal base (horizontal foot), which allows bolting to plates or tables for secure and repeatable positioning.

Does the construction protect against corrosion?
The component is galvanised, offering enhanced corrosion resistance for typical workshop environments and reducing the need for intensive surface maintenance.

Can the clamp be integrated into existing pneumatic circuits?
Yes. The clamp features a pneumatic cylinder that can be connected to standard compressed-air supplies; for exact connection details and required air parameters, refer to the product documentation or consult Metav Werkzeuge.

What maintenance is required to ensure long service life?
Periodic inspection of pneumatic seals, checking for secure mounting, and light lubrication of moving joints will maintain reliable operation and long service life for the clamp.
