90° 6500 N Pneumatic Clamp Without Cylinder, Zinc-Plated, 30 kN Holding Force - Kukamet

Take advantage of the combination of robust holding force, galvanised durability and a compact horizontal-foot design to secure high-repeatability workholding in production. The clamp’s compatibility with customer-specified pneumatic cylinders and its lever-style 90° configuration make it a flexible choice for fixture systems; order via Metav Werkzeuge or consult our specialists for integration advice.

Pneumatic clamp 681 – Horizontal-foot 90° lever clamp (Kukamet)

The Pneumatic clamp 681 is a horizontal-foot, lever-style clamp designed for secure, repeatable workholding in industrial fixture applications and supplied without a pneumatic cylinder

• Galvanised steel construction
• Max holding force 30,000 N
• Actuating force up to 6,500 N
• Horizontal foot mounting
• 90° lever clamp configuration

Secure clamping that improves process reliability

The lever-style clamping mechanism delivers a clear distinction between actuating force and holding force, with an actuating peak of 6,500 N and a steady holding capacity of 30,000 N. This separation ensures that short control pulses from valve systems achieve fast closure while the high retention force maintains parts reliably during machining or assembly, reducing rework and scrap. The galvanised finish contributes corrosion resistance and long-term dimensional stability in workshop environments.

Compact mounting for flexible fixture integration

Designed with a horizontal foot and a 90° lever angle, this clamp suits fixture plates and custom jigs where lateral clearance and predictable clamp geometry are essential. The unit’s mass (approx. 11.3 kg) provides inherent stability without excessive bulk, allowing straightforward bolting to tooling plates. The compact footprint supports tight nest arrangements and faster changeovers, which is beneficial for medium- to high-volume production runs demanding short cycle times.

Adaptable supply concept and low-maintenance operation

Delivered without pneumatic cylinder, the clamp allows selection of a cylinder to match system pressure and control schemes, enabling tailored actuation speeds and integration with existing pneumatics. The galvanised material minimises surface wear and eases maintenance cycles, while the lever configuration offers simple mechanical inspection points. Supplied by Kukamet and distributed through Metav Werkzeuge’s quality-filtered supply chain, the device is intended for reliable workshop use across a range of production environments.

FAQ

What is the difference between actuating and holding force for this clamp?
The actuating force is the force required to drive the clamp into the closed position (6,500 N), while the holding force (30,000 N) is the retention capacity once the clamp is engaged; the Pneumatic clamp 681 separates these functions for efficient control and strong retention.

Is a pneumatic cylinder included with the clamp?
No, the clamp is supplied without a pneumatic cylinder so that an appropriate cylinder can be selected to match system pressure and cycle requirements when integrating the Kukamet clamp 681.

How is the clamp mounted to a fixture plate?
The clamp uses a horizontal foot mounting that is bolted to tooling plates or fixture bases; the horizontal-foot design and 90° lever geometry facilitate predictable clamping positions for jigs and fixtures.

Can the clamp be used in corrosive or humid workshop environments?
The galvanised steel construction provides enhanced corrosion resistance compared with untreated components, supporting longer service life in standard workshop conditions for the Kukamet Pneumatic clamp 681.
