681 Pneumatic clamp — horizontal-foot clamp, galvanised (Kukamet)

The 681 pneumatic clamp is a robust industrial clamping device for 90° applications, designed for horizontal-foot mounting and supplied without a pneumatic cylinder for flexible system integration.

• Robust galvanised steel construction
• 4,000 N maximum clamping force
• 18,000 N maximum holding force
• Horizontal-foot mounting, 90° clamping angle

Reliable clamping performance for demanding fixtures

The clamp delivers precise and repeatable clamping results thanks to its defined 4,000 N actuation capability and substantial 18,000 N static holding capacity. These two values describe different but complementary properties: the first refers to the active pressing force applied during engagement, the second to the maximum load the device resists once closed. This separation ensures a secure hold of components under load while allowing control over the actuation dynamics. The galvanised finish contributes to long-term dimensional stability by resisting corrosion in workshop environments, supporting uninterrupted production cycles and predictable fixture behaviour.

Simple integration and flexible actuation options

Equipped with a horizontal foot and a fixed 90° clamping orientation, the unit is intended for straightforward mounting on fixture plates and tooling frames where transverse clamping is required. As it is supplied without pneumatic cylinder, the clamp can be paired with a customer-selected actuator or an existing pneumatic system, allowing specification of stroke, speed and cushioning to match cycle requirements. The compact design and a moderate mass of 4.6 kg permit installation in both manual jigs and semi-automated assemblies while keeping the overall fixture footprint economical and serviceable.

Durability and low-maintenance design that keeps production running

Constructed from galvanised steel and engineered for workshop use, the device prioritises longevity and simple upkeep. The substantial holding characteristic reduces slipping and the need for frequent repositioning, lowering process disruptions and rework. Maintenance is limited to visual inspection and lubrication at scheduled intervals; the absence of a built-in cylinder reduces the number of wear items supplied with the clamp and makes replacement or upgrade of the actuator straightforward. These qualities help achieve consistent output and reduced downtime across assembly and machining tasks.

FAQ

What is the difference between clamping force and holding force?
Clamping force describes the active pressing capability (the 4,000 N figure for the 681 pneumatic clamp), while holding force denotes the maximum static load the closed clamp can resist (18,000 N) without slipping.

Is a pneumatic cylinder included with the clamp?
No, the clamp is supplied without pneumatic cylinder to allow selection of an actuator that matches cycle speed and stroke requirements.

Can the clamp be mounted on a horizontal plate?
Yes. The unit features a horizontal-foot mounting arrangement and a fixed 90° clamping orientation suitable for plate-mounted fixtures.

What materials is the clamp made from, and how does that affect service life?
The main components are galvanised steel, providing corrosion resistance that supports long service life in standard workshop atmospheres and reduces the frequency of surface maintenance.

How can the clamp be integrated into an existing pneumatic system?
The clamp’s actuator interface accepts an external pneumatic cylinder; selection of cylinder size and cushioning allows tuning of actuation speed, stroke and impact behaviour for the specific application and cycle.
