It is a cylindrical bush with an inner diameter of 18mm and an outer diameter of 22mm. The bush is typically made of steel or brass and provides a smooth and wear-resistant surface for the rocker roller to roll on.

Rocker roller arms are used in tandem and tri-axle trailer suspensions. They reduce friction and noise and can extend the life of the rocker roller.

Also, inspect the rocker arm steel hanger, as the bolt hole may be elongated.

If associated components show excess wear and tear, it is wise to replace the entire rocker arm and hanger.
