Cylinder Sleeve Peugeot Manufacturer China: Sourcing Guide
Procurement teams buying Peugeot cylinder sleeves need more than a part name. They need the engine code, sleeve type, material grade, machining allowance, and the inspection data that proves repeatability across lots. Driventus supplies engine and powertrain components from Taizhou, Zhejiang, and supports B2B programmes for aftermarket distributors, OEM/Tier-1 buyers, and repair networks. We export to more than 60 countries and work to IATF 16949:2016 and ISO 9001:2015 controlled processes. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only. For programmes that require regulatory or durability alignment, material and validation files can be mapped to REACH (EC) No 1907/2006, ECE R-83, or SAE J2527 at the assembly or vehicle level. The priority is a sleeve that fits the drawing, holds roundness after machining, and arrives with traceable inspection records.
What Buyers Should Verify First
A purchase order for a cylinder sleeve is only useful if the technical definition is complete. Before asking for price, confirm the engine family, sleeve type, and the exact installation method. Dry sleeves, wet sleeves, and flanged sleeves are not interchangeable, and the wrong fit can affect heat transfer, seal integrity, and rebuild life.
For a Peugeot programme, the sourcing team should request:
- Engine code and application year range
- Sleeve type: dry, wet, or repair liner
- Nominal bore, outer diameter, length, and flange geometry
- Interference fit or retention method
- Surface finish target after honing
- Packaging requirement, including rust protection and labeling
- Annual volume, forecast pattern, and target lead time
If the buyer already has an OE cross-reference file, it should be checked against the drawing and the physical sample, not assumed from a catalogue entry. That is the fastest way to avoid dimensional drift between batches and avoid paying for a part that only fits on paper.
Material and Dimensional Controls
Cylinder sleeves are usually specified in alloyed grey cast iron or ductile iron, depending on wear target, wall section, and thermal loading. The final selection depends on the engine family and the customer drawing, but buyers should always ask for the material declaration, hardness window, and the inspection method used for each critical characteristic.
| Control item | Typical buying check | Why it matters |
|---|---|---|
| Material grade | Cast iron family per drawing | Wear resistance and heat transfer |
| Hardness | Brinell or equivalent per spec | Ring life and scuff resistance |
| Roundness | Tight post-machining control | Bore sealing and oil control |
| Cylindricity | Measured on the finish bore | Consistent piston contact |
| Bore finish | Controlled honing pattern | Oil retention and break-in |
| OD and length | 100% or lot sampling | Fit in the block and deck height |
| Corrosion protection | Oil, VCI, or custom packing | Shelf life in export transit |
