12-Ton Columbia #169B-12-44S Hydraulic Roll Marking Machine – S/N B9340

1993 Columbia 12-Ton Hydraulic Roll Marking Machine

This 1993 Columbia #169B-12-44S is a heavy-duty hydraulic marking system designed for deep, permanent impressions on industrial components. Featuring a 12-ton hydraulic ram and a high-torque 3 HP motor, this rotary-slide machine is engineered to mark both cylindrical and flat surfaces with exceptional clarity.

By using a progressive "rolling" action rather than a single vertical impact, this machine achieves the marking depth of a 50-ton press while significantly reducing internal stresses on the workpiece. This unit (Serial #B9340) is a well-maintained example of American industrial engineering, built on a rigid 213T frame that ensures perfect alignment during high-volume production runs.

Key Highlights:

• 1993 Vintage: Features the robust mechanical reliability of 90s-era Columbia tooling.
• 12-Ton Rolling Pressure: Ideal for deep part numbering and branding on hardened steels and fittings.
• Dual-Voltage Versatility: 230/460V 3-phase configuration makes it compatible with most industrial shops.
• Rotary & Slide Capability: Includes the rotary fixture and horizontal pneumatic slide for maximum versatility.

In the early 90s, the 169B-12-44S was the industry benchmark for "Quiet" roll marking, as it replaced high-impact stamping with a smooth hydraulic rolling action. This specific unit features the REV - N4571 slide assembly, which was the final major revision to this series before Columbia transitioned to more complex electronic controls.
