Self aligning conveyor roller Customized/Wholesale

Short Description:

Self-Aligning Idler

Belts are the most expensive component of a conveyor system, and GCS China Conveyor Supply’s self-aligning idlers ensure that your belts stay on track, minimizing the possibility of serious belt damage.
Return self-aligning idlers for slot and return applications are used to overcome belt tracking errors by automatically providing belt alignment. They are manufactured to fit existing belt profiles and are constructed using center-pivot bearings. The lateral servo rollers sense the direction of the belt and move the roller carriage to the correct center position. They are available in offset and inline configurations

Self Aligning Roller for Belt Conveyor

GCS self-aligning roller keeps your conveyor on track. This helps reduce the risk of serious belt damage.

We produce 60 mm, 63.5 mm, 76 mm, 89 mm, 102 mm, 114 mm, 127 mm, 139 mm, 159 mm. They cover almost all belt width requirements. General steel rollers consist of a roller shell, spindle, bearing, bearing housing, sealing device, and axial fixing. It is recommended to install one or two sets of return centering idlers. Place them on the return side of the belt, near the tail pulley. They should be 6 to 9 meters from the pulley.

The idler side guide rollers have a concave shape to prevent the belt from running on the conveyor. To reduce belt wear, the side guide rollers are available in premium HDPE made, and are also available in plain steel Q235, reducing friction between the rollers and the belt.

How It works

The self-aligning rollers for conveyor belt use a pivoting frame or tilting structure. When the belt shifts to one side, the roller responds by rotating slightly. This small movement helps push the belt back to its proper position. There are two main types:

Self Aligning Carrying Roller: Positioned on the top side to support the loaded belt.
Self Aligning Return Roller: Installed underneath to support the empty return belt.

Custom Self Aligning Roller Solutions

Some conveyor systems need special designs.

At GCS, we offer custom self aligning rollers made to fit your conveyor’s size, load, and working conditions.

Whether you need different materials, sizes, or mounting options, we can help.
