Idler Pulley for MG ZS: Magnesium Alloy
This idler pulley for the MG ZS is specified around magnesium alloy, which decides how it behaves in service far more than the part name does. We build to a written specification — base material, dimensions, finish and packing — and hold that specification on file so every reorder reproduces the approved piece.
The usual reason a programme changes supplier is not unit price. It is lead time that slipped twice before bulk started, or lead time that slipped twice before bulk started. Both are specification problems, and both are preventable.

Questions buyers ask
How is packing specified?
Individual packing, inner box quantity and carton marking are confirmed at quotation stage so the cartons arrive ready for your warehouse.
What testing is included?
Standard lots ship with dimensional and hardness reports. RoHS documentation is issued with the shipment when your market requires it.
Can the specification be held on file?
Yes. Once approved, the specification is recorded against your part number so a reorder reproduces the RoHS-compliant build instead of a fresh interpretation.
What is the minimum order quantity?
The standard MOQ is 3000 pieces per specification. Mixed sizes inside one shipment are accepted once the total reaches that figure.
