521 push-rod clamp by Kukamet — 4,500 N pressing force, zinc‑plated

The 521 is a compact push‑rod clamp designed for workshop and light production clamping, equipped with a horizontal foot for stable attachment and precise pressure control

• 4,500 N maximum pressing force
• 7,200 N holding force
• Zinc‑plated corrosion resistance
• Horizontal‑foot mounting for stability

Consistent clamping power for repetitive tasks

The clamp delivers a clear performance profile: a maximum pressing force of 4,500 N and a holding force of 7,200 N, which together provide secure retention for many standard fixturing operations. These figures indicate how much force the device applies during engagement and how much load it can reliably hold once set. For processes that require repeated, consistent clamping — for example assembly jigs or fixture workpieces in a small production run — the combination of pressing and holding force reduces slippage and rework, improving throughput and repeatability.

Durable finish and compact footprint reduce downtime

A zinc‑plated finish protects contact surfaces against corrosion, extending service life in workshop environments where humidity or coolant exposure can otherwise accelerate wear. The unit’s compact design and 0.825 kg mass make it simple to integrate into existing fixtures without adding unnecessary bulk or weight. The horizontal foot mounting arrangement supports low‑profile installation on plates and beams, saving vertical space while providing a stable basis for repeated clamp engagement.

Simple integration and precise adjustment

Adjustment is effected through the M10x70 pressure spindle, a standard metric thread and length that permits straightforward matching with common fixtures and replacement parts. The clamp uses an 18 mm piston diameter, which determines the active clamping area and the force transmission characteristics; a larger piston diameter typically yields smoother force delivery with less spindle travel. These features mean the device can be incorporated into jigs with predictable behaviour and minimal bespoke machining, lowering integration effort and easing maintenance.

Practical workshop applications and efficiency gains

The unit suits routine clamping tasks in workshops, on benches and in light assembly lines where reliable, repeatable holding is required. Its robust holding capacity supports secure fixturing of small to medium components, while the zinc‑plated surface reduces the need for frequent replacement. By standardising on compact, metric‑threaded clamps with known force values, process planners can simplify parts lists and speed setup times, contributing to leaner workflows and fewer stoppages due to loose workpieces.

FAQ

What clamping and holding forces does this clamp offer?
The Kukamet 521 push‑rod clamp provides a maximum pressing force of 4,500 N and a holding force of 7,200 N, values suited to many bench and light production fixturing tasks.

How is the clamp mounted and adjusted?
Mounting is via a horizontal foot; adjustment of clamping pressure is made using the M10x70 pressure spindle supplied with the unit.

Is the finish resistant to workshop conditions?
The zinc‑plated finish on the 521 offers corrosion resistance appropriate for typical workshop environments, helping to prolong service life under normal use.

What does the piston diameter mean for performance?
An 18 mm piston diameter governs the area over which clamping force is applied, affecting how force is transmitted and how smoothly the clamp operates during engagement.

Which tasks is this clamp typically used for?
Common applications include fixture and jig clamping in small production runs, assembly tasks and general workshop fixturing where compact, repeatable holding is required.
