Rubber-lagged rollers are produced by hot-vulcanising rubber onto the steel roller shell. The lagging improves grip between belt and roller, protects the shell from abrasive material and reduces build-up.
They are used under chutes for impact damping, on the return side to prevent sticking, and in corrosive environments. Lagging thickness and hardness are chosen for the application.
