REACH Compliance for Idler Pulley Sourcing
Procurement teams usually treat an idler pulley as a simple rotating part, but REACH compliance is about the full article: pulley body, bearing, grease, coatings, seals, and sometimes packaging. For a buyer, the practical question is not whether the part looks identical, but whether the supplier can document substance control, screen SVHCs against the current Candidate List, and keep records tied to a stable BOM. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only. For repeat sourcing, ask for material declarations, process statements, and a signed REACH declaration that covers the exact revision you are buying. This is especially important when the design includes zinc plating, polymer pulleys, or pre-packed grease. The notes below explain what to verify, which documents to request, and how to keep the file clean for internal audits and customer reviews.
What REACH means for this part
For an idler pulley, REACH compliance means the supplier can show that the article and its input materials do not contain restricted substances above applicable thresholds, or that any presence is declared correctly. This is a documentation and control issue, not a label exercise.
In practice, buyers should ask whether the pulley is supplied as a finished article, whether the bearing grease is covered, and whether any plating or paint is applied by subcontractors. The answer should be tied to a revision-controlled BOM, not a generic company statement.
A valid sourcing file should also align with the supplier's wider controls under our quality system. If the supplier cannot map the exact part revision to the declaration, the risk is usually traceability, not just chemistry.
Materials and finishes to screen
The highest-risk inputs are usually not the pulley body itself, but the materials added during finishing and assembly. A metal wheel, polymer wheel, bearing seal, lubricant, or coating can each change the compliance status.
Typical points to verify:
- Steel or aluminium body: confirm alloy family, coating type, and process revision.
- Polymer pulley: check resin grade, fillers, pigments, and recycled content claims.
- Bearing unit: request grease declaration and seal material identification.
- Surface treatment: verify zinc, phosphate, black oxide, paint, or passivation.
- Packaging: check inks, adhesives, and desiccants if supplied with the part.
If you are building a multi-part programme, the same screening logic should be applied across our catalog and, where relevant, engine components.
Documents buyers should request
A supplier should be able to provide a file that is current, signed, and traceable to the exact part number or drawing revision. The declaration is the starting point. It is not enough on its own unless it is backed by material data and change control.
| Document | What it should cover | Why it matters |
|---|---|---|
| REACH declaration | Exact part, revision, and current status against restricted substances | Confirms the supplier is screening the right item |
| Material declaration | Metal, polymer, grease, seal, and coating inputs | Shows where the risk sits in the BOM |
| SDS or equivalent substance data | Lubricants, paints, cleaners, and process chemicals | Supports review of hidden chemistry in assembly |
| Change notice procedure | Subcontractor, coating, grease, or resin changes | Prevents silent drift after approval |
| Traceability record | Lot, batch, and production date | Makes audits and claims faster to close |
