D2848 Cylinder Liner – Heavy-Duty Performance Edition

Factory & Expertise As a specialized manufacturer of heavy-duty diesel engine liners, we focus exclusively on commercial and industrial engine components. Our facility is certified to ISO 9001 and IATF 16949 standards, with 18+ years of experience serving OEMs, rebuilders, and global wholesalers. Every D2848 liner is produced in-house, from raw material melting to final inspection, ensuring consistent quality and traceability.

Product & Fitment Details • Engine Compatibility: MAN D2848 V8 diesel engine (heavy trucks, power generators, construction machinery) • Core Specifications: 128mm bore, precision-machined dimensions to match OEM fitment • OE Cross-References: 51.01201.0309 / 65.01201.0049 / 227WN37 • Key Features: ◦ Anti-corrosion phosphate coating for long-term storage ◦ Sealing grooves and flange machined to exact tolerances ◦ Optimized wall thickness for heat dissipation and structural strength

Advanced Manufacturing Process Our D2848 liners are made using high-chromium alloy centrifugal casting, creating a dense, uniform grain structure for superior wear resistance. The inner bore undergoes a 3-stage honing process, producing a controlled cross-hatch pattern that retains oil while minimizing ring friction. Each unit is individually pressure-tested, checked for roundness, and verified against dimensional standards to eliminate fitment issues.

Differentiated Advantages

1. Extended service life: The high-chromium cast iron formulation resists scuffing and thermal deformation, even under continuous high-load operation.

2. Reduced oil consumption: Precision honing ensures optimal ring seating, helping to eliminate common oil burn issues in rebuilt engines.

3. Engineer-approved fit: Designed to meet or exceed OEM specs, our liners drop into D2848 blocks without modification, saving installation time.

4. Wholesale-friendly support: Flexible MOQs, custom labeling, and stable production lead times to support your bulk orders and fast-moving inventory.

We also offer matching pistons, piston rings, and full overhaul kits for the D2848 engine. Reach out to request a quote, technical data sheet, or sample for testing.
