AMF Pushrod clamp No. 6844 (Size 3) — short design, 2500 N clamping force

AMF Pushrod clamp No. 6844 is a compact pushrod clamp designed for reliable clamping in confined machine and assembly environments

• Short design for compact installations
• Push force up to 2500 N
• 40 mm stroke for secure engagement
• Actuation screw M8 x 35

Minimise setup time with compact, powerful clamping

The compact short design delivers a high clamping force in a small envelope, making it suitable for fixtures where space is at a premium. With a maximum holding and pressing force of 2500 N and a 40 mm stroke, this clamp enables fast, repeatable locking of workpieces while reducing interference with adjacent tooling. The combination of high force and reduced footprint helps to maintain production flow and reduce cycle interruptions without sacrificing grip strength.

Straightforward integration and clear technical interfaces

Designed for easy assembly into existing fixtures, the clamping unit features an M8 x 35 actuation screw and an M20x1.5 thread for secure mounting. Key dimensions such as H1 123 mm, L1 108 mm, A 12 mm and B 57 mm provide predictable clearances for layout planning. The plunger stroke and mounting threads are specified to industry conventions, which simplifies retrofitting and minimises engineering time. For less experienced users, this clear specification set reduces uncertainty during installation and commissioning.

Reliable performance in repetitive production environments

Built for repeated cycles, the device shows consistent holding characteristics suitable for assembly, jigs and light machining tasks. The robust actuation geometry and defined HW range 22–35 mm ensure secure contact and predictable behaviour under load. Where process stability is essential, this clamp contributes to lower scrap rates and improved throughput thanks to predictable positioning and dependable engagement. The product’s mechanical simplicity supports ease of maintenance and long service intervals.
