Schmidt manufactures a variety of roll marking machines and tooling to roll mark round, cylindrical, and flat parts. Roll marking is an economical solution for applications where tonnage requirements make a press marker too costly. It offers a practical solution where fragile parts would be damaged by heavy stamping pressure.

Schmidt Roll Marking MachineSchmidt roll markers offer many benefits:

  • Flexibility to mark round or flat parts
  • High Speed & High Production rotary units
  • Can be configured with part feeding systems
  • Less operating noise than marking presses
  • No impact damage to parts
  • Low equipment costs versus heavy presses
  • Dies last longer and work better
  • Quick tooling changes

Pneumatic Roll Marking Machines
For marking flat or round parts with minimal tonnage requirements.

Hydraulic Roll Marking Machines
For 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 either roll or press marking 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 fixture for Roll Markers

Roller Bearing Cradle:

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.

Standard Roller Bearing Cradles
Stock Numbers Model Number Work Diameters
032721 9701-0B 1/4" to 7/16"
032722 9701-1B 3/8" to 1"
032723 9701-2B 3/4" to 2"
032724 9701-3B 1-3/4" to 4-1/2"


Knurl Carriage for Roll Markers

Round (Knurl) Support Carriage:

Knurl support carriages are designed to hold and support round type holders and solid lettering knurls. The carriage is mounted to the machine die slide for roll marking flat parts. Several sizes are available in stock in both t-slot and dovetail mounts.

Stud Arbor Fixture for Roll Markers

Stud Arbor Fixture:

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.

Aluminum Gas Cylinder Part Marking:

A manufacturer of high and low pressure aluminum compressed gas cylinders needed a safe, fast and quiet direct part marking solution.

Custom hydraulic roll marking machine for gas cylindersThe cylinder manufacturer previously used hand stamps to mark directly on the cylinder, with five pieces of information — cylinder specifications, pressure rating, serial number, date of manufacture and the company’s name.  This marking process proved to be to slow given all the information required on each cylinder. The company relied on Schmidt to solved their problem and automated their process. This was done using a Schmidt custom hydraulic roll marking machine that became integrated right into the production line.  Schmidt developed a system to accept the various cylinders after they are pressure tested. A special engineered device positions the cylinders in the roll marker and then re-positions them to continue down the line.
