When a drum motor or motorized roller model is withdrawn, the exact part number often leads nowhere — the series may be discontinued or the code restructured. The faster route is cross-referencing: capture the mechanical and electrical attributes that define the roller and match them to a current alternative. This guide covers what to read and how to turn it into a replacement specification.
What defines interchangeability
A roller is defined by its size and how it is driven. Capture these before looking for a substitute:
| Parameter | Why it matters |
|---|---|
| Diameter | Roller outer diameter in mm |
| Length | Face length vs the conveyor width |
| Shaft | Male or female, keyed or threaded |
| Load | Payload per roller |
| Speed | Conveying speed in m/min |
| Voltage | 24 V DC (motorized) or three-phase (drum motor) |
A nameplate photo plus the diameter and length is usually enough for a specialist to propose a match.
Notes by roller type
- Drum motors (Interroll DM 0080 / 0113 / 0138): three-phase, the motor sealed inside the roller.
- Motorized rollers (EC 110 / 310 / 500): 24 V DC, driven through a controller.
- Conveyor rollers (Series 1100 / 1700): idle rollers sized to width and load.
- Modular platform (MCP): frames, belts and transfers around the rollers.
- Cross-belt sorter: the sorting application built on the rollers above.
How a cross-reference is built
- Record the original code and capture a nameplate photo.
- Note the diameter, length and shaft type.
- State the load and conveying speed.
- Confirm the voltage (24 V DC or three-phase) and control.
- Line-test the speed and direction before full rollout.
Why use a sourcing specialist
A given roller duty is met by several diameters and drive types — Interroll covers conveyor rollers, drum motors and motorized rollers. A sourcing partner keeps the range on file, checks the candidate against your nameplate, supplies procurement documentation, and can often ship a stocked equivalent within a day or two instead of waiting on a long factory lead time.
