Import Cylinder Liner — Buy in Bulk from Supplier in China

The cylinder liners from Olite Cylinder Liner Co., Ltd are wet-type, cast iron sleeves designed for insertion into engine blocks in diesel and gasoline engines. These liners are manufactured to replace worn bores in industrial, marine, and automotive engines, with bore diameters ranging from 80 mm to 130 mm. The wall thickness varies between 4.0 mm and 6.5 mm, depending on engine size and application, following standard industry tolerances for replaceable liners.

The material is high-phosphorus grey cast iron with a flake graphite structure, providing natural lubricity and vibration damping. Surface hardness ranges from 180 to 220 HB, and the inner bore is honed to a cross-hatch pattern at 45 degrees, with a roughness of 0.4 to 0.8 micrometers Ra. The outer surface is machined for interference fit, typically with a 0.05 mm to 0.12 mm press fit into the engine block. These are not plated or coated liners, as per standard for replaceable sleeves.

Primary buyers include engine overhaul facilities in Southeast Asia, Africa, and Eastern Europe, as well as OEMs producing small industrial engines. Orders are typically shipped in bulk cartons of 50 to 200 units, with neutral packaging or custom branding available. Trade terms are commonly FOB Jiangxi Port or CIF, with lead times averaging 20 to 35 days. Buyers should confirm the liner’s flange design and coolant passage alignment with their engine block before ordering.

The company specializes in manufacturing wet-type cylinder liners for replacement markets. It does not produce engine blocks, pistons, or cylinder heads.

Buyers should treat this as a manufacturer of standard replaceable liners, not a technology partner.
