AMF Push‑rod Clamp No. 6840, Size 3 — 2,500 N clamping, 32 mm stroke

The AMF Push‑rod Clamp No. 6840, Size 3 is a compact industrial clamp for secure, repeatable workpiece holding in fixtures and machining jigs, supplied without an angled base for flexible mounting.

• 2,500 N clamping force
• 32 mm stroke
• M20x1.5 threaded actuator
• Compact Size 3, no angled base

Consistent clamping performance that improves cycle stability

The push‑rod unit delivers a clamping force of 2,500 N, engineered to maintain secure contact during machining or assembly operations. High, repeatable holding values reduce the need for rechecks between cycles and therefore contribute to shorter overall process times. The linear actuator arrangement with a 32 mm stroke gives a practical travel range for typical fixture tolerances, ensuring consistent pressure application across varied workpiece heights and minimising setup adjustments.

Space‑saving design for versatile fixture layouts

A small footprint and the absence of an angled base allow the clamp to be integrated into confined jigs or banked fixture plates without compromise. The mechanical interface is prepared for a M20x1.5 threaded connection and includes a thrust screw of M8 x 35, enabling straightforward mechanical fixing and straightforward connection to existing tooling assemblies. The slim profile supports denser station layouts while retaining the mechanical integrity required in production environments.

Low‑maintenance construction for reliable uptime

Built for repetitive operation, the clamp’s mechanical principle emphasises durability and simple servicing. The robust construction minimises wear on moving parts and keeps maintenance intervals long, which supports predictable production planning. Where quick checks are required, readily measurable parameters such as stroke and thread engagement allow rapid visual inspection and straightforward corrective action without specialist tools.

Practical applications and compatibility in workshop use

Ideal for medium‑duty clamping tasks in metalworking fixtures, assembly jigs and test rigs, the unit adapts to a range of production tasks thanks to the adjustable working height (B min 24 mm – B max 56 mm) and a defined approach dimension (A 12 mm). The clamp suits repetitive positioning and holding duties where a reliable, mechanical solution is preferred over pneumatic variants, particularly when electrical or compressed‑air supplies are limited.
