Cylinder Liners produced by Keyhan Sanat Ghaem, with a 40-year history, are the first and most important products in the portfolio of Ghaem Supply Company. These Liners are manufactured in dry and wet types, air-cooled and water-cooled versions, as well as for dual-fuel engines, using advanced equipment and modern production lines.

Why Choose Ghaem Liners?

Material Variety and Applications

Cylinder Liners are produced using specialized materials tailored to different working conditions. Precise material selection increases durability, wear resistance, and high-temperature tolerance. These materials are designed for various applications, from light-duty engines to heavy industrial engines. Consequently, the final product delivers optimal performance under harsh conditions such as high temperature, high pressure, and continuous friction. Additionally, the metallurgical laboratory operates 24/7 to monitor all critical parameters of raw materials and final products.

Size Range and Technical Specifications

Ghaem Industrial Group can manufacture cylinder Liners with an inner diameter ranging from 55 mm to 350 mm, enabling their use in both light and heavy engines. The Liners are produced with high dimensional accuracy and comply with international standards to ensure optimal performance and long service life.

Advanced Honing Process

One of the key production steps is the honing process, performed at Keyhan Sanat Ghaem using two advanced methods: Plate Honing and Super Honing. This process enhances dimensional precision, improves the Liner’s internal surface, optimizes frictional performance, and—most importantly—ensures optimal lubrication right at engine start-up.

Advanced Equipment and Quality Assurance

Production takes place on CNC-equipped lines and with industrial robots under highly advanced quality control systems. A 100% robotic inspection guarantees each piece is delivered to customers with flawless precision and quality. Compliance with ISO standards and the use of modern technologies ensure high quality, consistent performance, and official product warranties. A widespread after-sales service network supports customers nationwide.

Applications and Benefits

Due to precise design and high-quality materials, Ghaem’s cylinder Liners reduce friction and improve engine efficiency. The advanced honing processes optimize lubrication, especially at engine start-up, enhancing durability, reducing fuel consumption, and lowering emissions. These Liners are widely used in passenger cars, agricultural machinery, construction equipment, and power generation engines.
