Trunnion Rollers: A hard-working, versatile piece of equipment

An Agitator or Trunnion Roller is a type of rotary roller used in machinery to support a rotating cylindrical part, such as a drum, screen or trommel.

The product consists of a cylindrical roller or a set of rollers that is mounted on a stationary shaft – which is perpendicular to the axis of rotation of the part being supported. The rollers allow the cylindrical part to rotate smoothly and reduce friction and wear on the supporting structure.

Agitator and Trunnion Rollers are commonly used in a variety of industrial applications, including cement and mineral processing plants, paper mills, and oil refineries. They are typically made from durable materials such as cast iron, steel, or alloy steel, and are designed to withstand high loads.

Agitator and Trunnion Rollers are critical components of machinery and require regular maintenance and inspection to ensure proper functioning and prevent breakdowns.

While there are many causes that can lead to the eventual replacement of your Agitator or Trunnion Rollers – such as excessive grinding and skewing – plant managers and machine operators can benefit from a dynamic maintenance schedule that allows for downtime of selected drums each month.
