Safety First
Here are some safety instructions for the Ring Roller. Remember... SAFETY FIRST!!!
- Always be aware of the position of the clamp handle and the counterweight. They are heavy and can swing back suddenly causing serious body or head injuries.
- Keep hands and fingers away from the rollers when the machine is in operation.
- Keep hands and fingers clear of any gears or mechanisms. Make sure guard is in place before operating machine.
- Keep hands and fingers from between the roller and die when bending materials to avoid possible injury.
Description
A ring roller is a machine used to roll metal into a ring by forcing the material through rollers, also called dies. The rollers can be adjusted to change the formed radius. The maximum mild steel machine capacity is 1/4" x 1" flat bar or 1/2" round rod. The minimum diameter you can form is 2.75"
Here is an example of this piece of equipment being used.
Documentation
Terminology
- Dies - Round pieces of steel used to guide the material as its shaped.
Training
Operation
The Ring Roller is a manual roll bender used to form rings, curves, and arcs from flat bar, round bar, or tubing. Operation involves selecting the correct roller set for the material, placing the workpiece between the rollers, and adjusting the top roller downward to apply bending pressure. The operator then turns the crank handle to feed the material through the rollers, gradually tightening the top roller in small increments until the desired radius or ring diameter is achieved.
Demonstration
Demonstrate you can safely setup the Ring Roller. You will then proceed to cut a 5" long piece of 1/4" steel rod. Roll this material into the smallest radius possible. When rolling the material remember to keep your fingers away from the rollers to keep from smashing your fingers.
General Procedure
- Adjust the knob on the right to adjust the radius, loosen the handle on the left if it restricting you from adjusting the right one.
- Make sure both knobs are secure and tightened before rolling, always start by rolling the largest radius, and work your way up from there.
- Insert the bar between the rollers.
- Turn the crank to roll the metal bar or rod.
- Start with a large radius and continue to make the radius smaller every time you roll. If you attempt to roll a small radius all at once, the rod may make a corkscrew shape instead of a circle.
- You have completed the roll when the two ends overlap each other by a couple of inches to account for the ends of the bar or rod that stay straight.
Reset the Space
Here is how you can reset the space for the Ring Roller. Always reset the space!!!
- Release the pinch roll.
- Remove the material.
- Return all unused stock.

Troubleshooting
- Material slipping – Tighten the top roller adjustment or use a roller set that matches the material profile.
- Uneven bend – Ensure material is fed straight and apply consistent pressure throughout the bend.
- Material kinks – Reduce roller gap increments and make multiple passes instead of one heavy pass.
- Difficulty turning crank – Check for roller lubrication and remove any debris or burrs from rollers.
- Roller wear or damage – Inspect for flat spots or cracks; replace rollers if necessary.
- Inconsistent ring size – Verify roller settings remain unchanged during bending and measure frequently.
Maintenance
General maintenance
The only things that need to be done to maintain the Ring Roller are general cleaning and periodic lubrication. For details on the lubrication process see the user manual.
