4. Diameter range from 55 to 250mm.
5. Surface treatments such as oxidation phosphating, plasma, and laser hardening.
6. Certified by DIN/ISO 4383 and ISO/TS 16949.
**Installation Instructions:**
- **Wet Cylinder Liners:** Ensure the bore and running surfaces are clean and undamaged. Corroded areas should be reworked using flange or oversized liners. Check that the liner fits properly and aligns correctly with the engine specifications. After installation, check the cylinder diameter around the seal ring area to prevent deformation caused by incorrect seals. Perform a pressure test on the cooling system to detect any leaks before starting the engine.
- **Semi-Finished Cylinder Liners:** The supporting surface of the flange must be perpendicular to the location bore and evenly beveled. If the flange is unevenly supported, it may tear off. After installation, the inside diameter is finely bored and honed to meet specified dimensions. The liner surface must be flush with the cylinder block’s sealing surface, and if necessary, both the block and liner should be ground.
- **Finished Cylinder Liners:** Before installation, the location bore in the cylinder block must be cleaned and checked for accuracy. Out-of-center or damaged bores can be reworked for oversized liners. The locating bore must be cylindrical to maintain the correct shape of the pressed-in liner.
- **Air-Cooled Cylinder Liners:** Cast iron or light alloy cylinders are used depending on the engine manufacturer's instructions. Light alloy cylinders are grouped due to tight installation clearances.
