PRODUCTS DESCRIPTION

Engine parts list

Product Description

This cylinder liner assembly matches 6BT5.9, 6CT8.3, K38, NT855 series engines for excavation machinery. It is a core pressure-bearing component of engine power system. The complete set consists of cylinder liner, matching sealing and limit accessories. Each part is packed separately with anti-counterfeiting labels, and bulk goods are neatly packed in unified cartons. It is used for replacement and maintenance of power assemblies on earthmoving, mining and infrastructure excavation equipment. Processed to standard original size, it can directly replace worn parts without modification, ideal for heavy-duty equipment overhaul and regular spare parts stocking at construction sites.

Product Advantages

Full model compatibility: Compatible with four mainstream engineering engine models, realizing one-stop procurement and cutting multi-channel stocking costs.
Complete supporting set: Equipped with standard sealing gaskets and positioning accessories, ready for installation upon arrival with no extra parts needed.
Strict original manufacturing technology: Produced on standardized assembly lines, each piece with independent traceability label for consistent stable quality.
Wear-resistant material: Made of high-hardness alloy cast iron, resistant to high temperature and corrosion, perfectly suitable for dusty harsh mining working conditions.
Reliable protective packaging: Small parts sealed by plastic bags, large parts packed in thickened cartons to avoid collision and deformation during long-distance transportation.
High maintenance universality: Precise dimensional tolerance ensures easy disassembly and assembly, shortening maintenance time and reducing equipment downtime losses.

Product Performance

High temperature resistance: Able to sustain long-term high-temperature combustion environment inside cylinder with minimal thermal deformation, maintaining tight seal of combustion chamber.
Excellent wear resistance: Inner wall processed by precision honing technology to reduce friction from piston reciprocating movement and greatly extend engine overhaul interval.
Pressure sealing performance: Matched with supporting sealing parts, no water leakage or gas blow-by under high-pressure working conditions to stabilize cylinder compression pressure.
Anti-corrosion performance: Alloy anti-corrosion composition added in base material to resist corrosion from diesel sulfide and acid-base coolant, extending service life.
Stable dimensional accuracy: Processed by CNC machine tools with ultra-low tolerance of roundness and cylindricity, preventing piston eccentric wear and cylinder scoring failures.
Wide working condition adaptability: Operates stably under continuous heavy load, intermittent impact, low temperature and plateau environments for all kinds of excavation machinery.
