Cylinder Liner Infiniti Manufacturer China: Sourcing Guide
Buyers searching for a cylinder liner Infiniti manufacturer China usually need more than a low price. They need a supplier that can match bore size, wall thickness, skirt finish, ring travel, and heat-treatment requirements to the engine code they are servicing or building. For importers, the commercial risk is not only dimensional error; it is also inconsistent metallurgy, porosity, coating adhesion, packaging damage, and weak traceability across batches. Driventus supplies engine components from Taizhou, Zhejiang, with export experience in 60+ countries and quality controls built around automotive procurement needs. Driventus is an independent aftermarket manufacturer; brand names are referenced for fitment only. The practical sourcing questions are simple: can the factory hold tolerance, document the process, support sample approval, and scale without changing the part?
What buyers should verify for Infiniti applications
When sourcing a liner for Infiniti engine programmes, the first task is fitment control. Buyers should confirm the engine family, bore diameter, liner height, flange geometry if present, interference fit, and whether the block uses a dry liner or a wet liner design. A sample that looks correct is not enough; the dimensional stack-up must match the block and piston set that your customer actually uses.
Useful buyer checks:
- Engine code and displacement from the vehicle or engine list
- Bore size after machining, not only nominal catalogue size
- Liner protrusion, seating depth, and chamfer requirements
- Material grade, hardness range, and surface finish
- Ring land compatibility and honing allowance
- Packaging method for sea freight and warehouse handling
For reference browsing, start with our catalog or the engine components section if you are mapping a wider repair programme. If you are comparing a cylinder liner Infiniti manufacturer China against other sources, ask for drawings, photographs of metrology reports, and sample history before you move to production.
Dimensions, materials, and tolerances
A cylinder liner is a precision wear component, so the sourcing spec should be written around measurable limits. For procurement teams, the important variables are not generic marketing claims but repeatable numbers that the supplier can hold across lots.
| Parameter | Buyer should define | Why it matters |
|---|---|---|
| Bore diameter | Nominal size and tolerance band | Controls piston clearance and oil control |
| Outer diameter | Interference or slip fit target | Prevents block movement or distortion |
| Length / height | Overall and seating reference points | Affects deck height and sealing |
| Wall thickness | Minimum and average wall thickness | Influences rigidity and heat transfer |
| Surface finish | Honing and roughness target | Supports ring bedding and wear control |
| Material | Alloy cast iron or customer-defined grade | Impacts wear resistance and machinability |
