PGC Engine Parts manufactures and exports precision-engineered cylinder liners and sleeves for automotive, commercial, agricultural, marine, industrial, and heavy-duty engine applications. Our products are designed to provide a reliable cylinder running surface with excellent resistance to wear, friction, thermal stress, combustion pressure, and continuous piston movement.
Manufactured from carefully selected grey cast iron and alloy cast iron, our cylinder liners and sleeves are produced using controlled casting, heat treatment, precision machining, honing, and finishing processes. Accurate bore geometry, wall thickness, concentricity, hardness, and surface finish are maintained to support proper piston and ring operation, effective heat transfer, and long-term dimensional stability.
PGC Engine Parts can manufacture products according to OEM specifications, customer drawings, samples, engine models, part numbers, and customized technical requirements.

Key Benefits
High Wear Resistance: Provides reliable performance against cylinder wear, abrasion, and friction.
Efficient Heat Transfer: Supports effective heat dissipation and stable engine operating temperatures.
High Strength & Durability: Designed to withstand combustion pressure, thermal cycling, and continuous mechanical loads.
Precision Fitment: Accurate dimensions, bore geometry, and surface finish ensure proper installation and piston-ring operation.
Cost-Effective Maintenance: Replacement of worn liners can help restore cylinder performance without replacing the complete engine block.
Material Options
Grey Cast Iron
Widely used for automotive and industrial engines due to its good machinability, wear resistance, vibration damping, and lubrication retention characteristics.
Alloy Cast Iron
Alloyed grades may contain chromium, nickel, molybdenum, copper, vanadium, and other elements to achieve improved hardness, strength, wear resistance, and thermal stability.
Material grades can be selected according to engine requirements, OEM specifications, customer drawings, and applicable standards.
Applicable Standards
Cylinder liners and sleeves can be manufactured according to customer-specified material standards, including:
ASTM: A48 Class 30/35/40, ASTM A159
DIN: GG20, GG25, GG30 and applicable GGG grades
JIS: FC250, FC300
EN: EN-GJL-250, EN-GJL-300
The applicable material grade should be confirmed based on the required chemical composition, mechanical properties, and engine application.
Manufacturing & Quality
Our manufacturing process may include casting, heat treatment, rough machining, precision machining, honing, grinding, and surface treatment. Depending on the application, liners can be supplied in semi-finished or fully finished conditions with phosphating, nitriding, or chrome plating.
Quality inspection can include bore diameter, outside diameter, wall thickness, length, concentricity, roundness, surface finish, hardness, material composition, microstructure, and dimensional conformity.
PGC Engine Parts also supports custom manufacturing based on OEM part numbers, technical drawings, samples, engine models, and special material or finishing requirements.
PGC Engine Parts - Precision cylinder liners and sleeves engineered for durability, dimensional accuracy, and dependable engine performance.
These liners are made to handle the expansion and contraction that happens when the engine is running. They also have to be strong enough to withstand pressures from combustion while keeping their shape and working reliably. Cylinder liners are important, for engine performance and PGC Engine Parts manufactures them to ensure engines run smoothly
