Ajax MN Series Mechanical Forging Press
Since 1998, the Ajax MN Series mechanical forging press has set the benchmark for high-output precision forging with mega newton force ratings, a wider pitman eccentric drive, and a stiffer frame that keeps your tolerances consistent at production speed.

Product Overview
Mega Newton Forging Press Performance, Engineered for Precision
Ajax built the MN Series around three upgrades that matter on the shop floor: a stiffer frame, a wider pitman eccentric, and stroking rates that outpace our standard press line.
Wide Pitman Eccentric Drive for Superior Process Control
The MN Series’s wider pitman eccentric gives the MN Series a mechanical advantage over standard press drives by increasing the load-bearing surface between the eccentric shaft and connecting rod. This reduces lateral play under heavy forging loads and keeps the ram tracking true at full speed.
Operations forging close-tolerance aerospace or automotive components gain measurable improvements in part consistency.

Eight-Point Ram Guide System for Closer Tolerances
Where conventional presses rely on four guide points, the MN Series eight-point ram guide forging press doubles the contact surfaces controlling ram position.
Each additional guide point resists torsional and lateral forces that cause misalignment under load. This means more accurate impressions on every stroke, less tool wear across die stations, and lower scrap rates over long production campaigns.

Key Features of the MN Series High Stroking Rate Forging Press
The MN Series high stroking rate forging press delivers production advantages through these core engineering features:
Cast Steel Frame
One-piece cast steel stress-relieved frame, with Tie Rod design on 80MN and above.
Eight-Point Ram Guides
Eight-point ram guide system for full-stroke positional control.
Wide Pitman Drive
Wide pitman eccentric drive with reduced shaft deflection.
Hydraulic Shut Height
Hydraulic wedge shut height adjustment for fast, precise die setup.
Air-Operated Clutch
Air-operated multiple plate friction clutch with overload protection.
Friction Slip Flywheel
Friction slip flywheel for maximum safety against overloads.
Bottom Knockout Options
Single-point and beam-type bottom knockout configurations available.
Hydraulic Wedge Shut Height Adjustment for Simplified Maintenance
A hydraulic wedge shut height adjustment press eliminates the need for manual tools during die height changes. The MN Series wedge system positions with repeatable accuracy, allowing operators to switch between jobs faster and return to full production sooner. Fewer manual touchpoints during setup also reduce the risk of human error that leads to off-spec parts on first strikes.

Programmable Controls and Automation-Ready Integration
Ajax engineered the MN Series to accept programmable controls and automation-ready electronic monitoring as standard integration points. Operators gain real-time visibility into tonnage, stroke, and cycle data while the press communicates directly with upstream feeders and downstream transfer devices.
