Difference between trunnion roller and support roller
Trunnion rollers and support rollers are two types of rollers commonly used in various industrial applications. While they serve similar functions of supporting and facilitating rotational movement, there are some key differences between them. Let's explore these differences:
Mounting Position
Trunnion Roller: A trunnion roller is mounted on a stationary trunnion or pivot point, allowing it to rotate around the trunnion axis. It supports and guides a rotating component, such as a drum or cylinder, that pivots around the trunnion.
Support Roller: A support roller is typically mounted on a frame or structure and provides support to a rotating shaft or drum by rolling along its outer surface. It does not pivot around a fixed axis like a trunnion roller.
Load Distribution
Trunnion Roller: Trunnion rollers are designed to handle both radial and axial loads. They provide support to the rotating component and distribute the load evenly along the trunnion axis.
Support Roller: Support rollers primarily handle radial loads and distribute the load evenly on the outer surface of the rotating shaft or drum.
Application
Trunnion Roller: Trunnion rollers are commonly used in applications where the rotating component needs to pivot or swing, such as kilns, mills, and rotary dryers. They are used to support and guide the rotating drum or cylinder.
Support Roller: Support rollers are utilized in various applications where a rotating shaft or drum needs support and smooth rolling motion. They are commonly found in conveyor systems, printing presses, material handling equipment, and other machinery.
Design and Construction
Trunnion Roller: Trunnion rollers usually have a larger diameter compared to support rollers. They are designed with a central shaft or axle mounted within a rolling element, such as a cylindrical roller bearing or a spherical roller bearing.
Support Roller: Support rollers have a smaller diameter compared to trunnion rollers. They are typically designed with a solid shaft or axle that rotates within a bearing or bushing arrangement.
Summary
In summary, trunnion rollers are mounted on a fixed trunnion axis and handle both radial and axial loads, providing support and guidance to a pivoting component. On the other hand, support rollers are mounted on a frame or structure, primarily handle radial loads, and provide support and smooth rolling motion to a rotating shaft or drum.
