Engine Cylinder Sleeves – Manufacturer and Exporter
Jaidarshan Indocraft Pvt. Ltd. manufactures centrifugally cast engine cylinder sleeves at our ISO 9001:2015 certified foundry in Ahmedabad, India. We supply engine remanufacturers, rebuilders and spare-parts distributors in over 21 countries, in standard sizes and to customer drawings, under our JAI NO 1 and MDT brands.
What Is an Engine Cylinder Sleeve?
A cylinder sleeve — also called a cylinder liner — is a cylindrical insert fitted into the engine block. It provides the running surface for the piston and piston rings, and protects the block from heat, friction and wear. When a bore wears beyond its service limit, fitting a new sleeve restores the engine at a fraction of the cost of replacing the block.

Dry Sleeves and Wet Sleeves
| Dry sleeve | Wet sleeve | |
|---|---|---|
| Coolant contact | None – full contact with the block | Outer wall in direct contact with coolant |
| Wall thickness | Thinner, typically 1.5–3 mm | Thicker and self-supporting |
| Cooling | Indirect, through the block | Direct, more even temperature |
| Fitment | Pressed into the block | Sealed with O-rings |
| Typical use | Automotive and light commercial | Heavy-duty, marine and generator |
We manufacture both types. If you are unsure which your engine requires, send us the engine make and model or the old sleeve, and our team will confirm.
Materials and Grades
Our sleeves are centrifugally cast in grey cast iron, SG (ductile) iron, low-carbon steel, stainless steel and Ni-Resist. Irons are alloyed with molybdenum, nickel, chromium and vanadium to improve wear resistance and corrosion resistance under high temperature and pressure.
Every heat is verified by spectrometer in our in-house metallurgy laboratory before casting is released.
Standards: IS 210, IS 1865, ASTM A48, EN-GJL and EN-GJS series
Size Range and Tolerance
| Inner diameter | 45 mm – 400 mm |
| Outer diameter | 50 mm – 500 mm |
| Length | Up to 650 mm |
| Bore tolerance | ± 0.03 mm |
Larger castings can be produced to customer requirement.
Machining and Finishing
Sleeves are finished on CNC, VMC and VTL machines, then ground and honed in-house. Cross-hatch honing is applied to specification so that the bore retains an oil film and seats the piston rings correctly during run-in.

Frequently Asked Questions
When should a cylinder sleeve be replaced?
When bore wear, ovality or scoring exceeds the engine manufacturer’s service limit, or when compression loss and oil consumption indicate the bore is no longer sealing.
What is the difference between a sleeve and a liner?
The terms are used interchangeably. “Sleeve” is more common in North America, “liner” in Europe and Asia. Both describe the same component.
Can you manufacture from a sample?
Yes. Send a physical sample, a drawing or the OEM part number and we will quote against it.
What tolerance do you hold on the bore?
± 0.03 mm as standard. Tighter tolerances can be discussed for specific applications.
Do you supply in matched sets?
Yes, sleeves can be supplied in matched sets for multi-cylinder engines on request.
