AMF Push‑pull Rod Clamp Nr.6842, Size 7 (Heavy‑duty) — 25,000 N, 50 mm stroke

The AMF Push‑pull Rod Clamp Nr.6842 is a heavy‑duty compression and tension clamp intended for industrial workholding and fixture applications where high holding forces and repeatable positioning are essential

• Heavy‑duty push/pull clamp, size 7
• 25,000 N maximum clamping force
• 50 mm stroke for deep engagement
• M12 x 50 pressure screw fitted

Secure, high‑force clamping for repeatable production

With a rated max. clamping force of 25,000 N and equal holding capacity, this rod clamp provides a measurable increase in fixture security compared with lighter devices. The combination of high force and 50 mm stroke reduces slippage under machining loads and improves repeatability of parts from batch to batch. Designed for demanding production environments, the unit supports stable machining, drilling and light milling operations by keeping components immobile during cycle times. Emphasis on measurable figures simplifies planning and risk assessment in process documentation.

Fast adjustment and straightforward integration into jigs

The clamp offers practical adjustability via an M12 x 50 pressure screw and a compact footprint in size 7, enabling simple setting of contact pressure and travel without complex tooling changes. Minimum and maximum flank dimensions (B min / B max) permit flexible positioning in bespoke fixtures; this reduces set‑up time and shortens changeover intervals. The mechanical interface is suitable for standard locating schemes, allowing rapid retrofit into existing clamping plates or custom jigs while preserving machine availability and throughput.

Built for continuous shopfloor use — confidence in every cycle

Specified as a heavy execution, the design prioritises durability under repeated load cycles. The robust mechanism and conservative force rating contribute to lower maintenance frequency and predictable service intervals, which translates into fewer unscheduled stops and a steadier production rhythm. For manufacturing teams, this reliability means less rework and improved delivery predictability, building operational confidence that supports long‑term production planning.

Practical selection notes to match process requirements

Selection should be guided by the required holding force and stroke rather than by brand alone; the 25,000 N rating and 50 mm travel make this clamp suitable where strong retention and moderate travel are required. Key dimensions such as A, C, H1 and L1 allow verification against fixture envelopes before purchase. If uncertainty remains over compatibility with a particular jig or machining sequence, technical consultation is recommended to ensure the clamp meets cycle, load and access constraints.
