Pneumatic Roll Marking Machines


Pneumatic roll marking machines are ideal for marking parts that require less stamping pressure than a press marking machine or a hydraulic roll marker. SCHMIDT's pneumatic roll marking machines offer 1.45 to 3 tons of marking force and are great for marking mild steel, tool steel and soft aluminum.

SCHMIDT's pneumatic roll marking machines can be custom built to fit your specific marking application requirements.

Pneumatic Roll Marking Machine Information

SCHMIDT offers two standard pneumatic roll marking machines, the Series 9 and the Series 12, which are both ideal for marking flat or round parts with minimal tonnage requirements. These pneumatic roll marking machines offer a range of marking pressures, die spaces, and table sizes. Both machines can also be custom built to fit your application needs including part feeders, safety guards, light curtains and special tooling.

Bench Top Roll Marking Machines - the Series 9

Series 9 Roll Marker

The Series 9 is a light-duty unit that offers clean pneumatic operation and outstanding performance with lots of operating flexibility. The standard Series 9 is designed for manual loading and unloading of parts. With a flip of a switch, the Series 9 can also be used as a press marker.


Floor Standing Roll Marking Machine - the Series 12

Series 12 Pneumatic Roll Marking Machine

The Series 12 is capable of roll marking your round or flat parts, as well as acting as a press marker. The benefit of roll marking is that the characters are applied one at a time. This reduces marking pressure and allows up to 4 lines of 1/8” characters, one character per line at the same time, in a single roll marking cycle. When operated in the press mode 4 - 1/8” characters can be applied.


Hydraulic Roll Marking Machines
For part marking applications that require additional power and force.

Rotary Roll Marking Machines
For the high speed, high production marking on the periphery of round cylindrical parts.

Tooling & Fixturing for Roll Marking Machines

Tooling and fixturing for roll marking machines is available in most cases from stock at SCHMIDT, custom options available. To roll mark round parts a roller bearing cradle and a straight type holder are necessary. To roll mark flat parts a round type holder and support carriage is required.


Roller Bearing Cradle:

Roller Bearing Cradle fixture for Roll Markers

Roller bearing cradles are fixtures that can be mounted on the tables of roll markers to support and locate solid round parts or heavy walled tubing for peripheral marking. Parts are loaded on these fixtures manually, and peripheral impressions are made using flat dies or straight type holders mounted in a machine slide. Dies roll over the periphery of the part causing it to rotate while marking. Standard cradles are carried in stock.

Special Cradles: We also make custom cradles to your specs.

032723 9701-2B 3/4" to 2"

Stud Arbor Fixture:

Stud Arbor Fixture for Roll Markers

Hollow round parts often are supported on arbors for marking. Plain Stud Arbor Table Fixtures are suitable where marking may appear at any point on the periphery. When a range of sizes needs to be marked, interchangeable stud arbors can be furnished for the same fixture base. A Spring Return Type Arbor is required for marking at the same starting point for each part. The spring return feature allows the stud arbor to return to its correct starting position after each marking cycle.
