What Are Roll Grooving and Beading? Uses of Tube Roll Forming and How to Choose a Machine
Table of Contents Menu
Roll grooving uses a roller to press a groove around the outside of a metal tube; beading presses a raised rib. Both are roll forming – no cutting, no chips, and the tube wall stays continuous.
What they are used for
- Locating: gives internal parts (guides, seals, pistons) a fixed position, e.g. in gas spring and tailgate strut cylinders.
- Retaining rings and anti-pull-out: provides a ring groove or keeps two telescoped tubes from separating.
- Stiffening and appearance: adds rigidity or a decorative ring.
Typical products
Gas spring and tailgate strut cylinders, conveyor roller tubes, furniture and telescopic poles, fitness equipment, lamp stands.
Quality points
- Consistent groove position and depth so parts locate accurately.
- No visible distortion or run-out after rolling.
- Accurate pitch when there are several grooves.

FAQ
Does grooving thin the tube wall?
Rolling displaces the metal rather than cutting it; the effect depends on the tube and groove depth – send samples for a trial.
Can several grooves be made at once?
Yes, with tooling and machine planned to the product.
