KONE Belt Roller

The KONE Belt Roller is a mechanical component used in elevator door operator belt transmission systems. It supports the movement and guidance of the door drive belt and is supplied for maintenance and replacement of worn or damaged door operator components.

Working With the Door Drive Belt

The belt roller forms part of the mechanical transmission between the door operator and the moving door system.

Depending on the door operator configuration, the roller may work as a guide, diverting or driven pulley for the timing belt.

Wear on the roller surface, bearing or belt contact area can affect smooth door movement and may contribute to abnormal noise or unstable belt operation.

Dimensions Are the Best Reference

Different KONE door systems use different belt rollers, so the product name alone is usually not enough for replacement identification.

Before ordering, please confirm:

• Outer diameter

• Roller width

• Inner diameter / shaft size

• Number of teeth, if toothed

• Bearing number

• Complete roller photos

• KONE part number, if available

• Related door operator model

• Required quantity

The original roller should be used as the main reference when the KONE part number is unavailable.
