The present study describes tribological properties of the textured surface applied with a roll forming process. A chromium alloy steel (SUJ2) disc was used for the specimen. Continuous and discontinues grooves were fabricated on the disc surface. A roller burnishing was applied to the textured surface after the roll forming for truncation. The tribological properties were evaluated with a ring on disc type testing apparatus in lubricated condition. Results showed that the friction coefficient of narrow pitch grooved surface was low and stable. In particular, the friction coefficient was smaller at the beginning of the experiment.
