Import Benz Om352 Engine Piston — Buy in Bulk from Supplier in China

The Benz OM352 engine piston is a replacement component for Mercedes-Benz diesel engines, specifically engineered for the OM352 inline-six series and cross-compatible with variants including OM352A, OM601, OM616, and M104 applications according to the supplier's listing. Cnflap Engine Parts (GZ) Ltd. sources or manufactures this piston in Guangzhou, China, with a construction aimed at withstanding the thermal and mechanical loads of indirect-injection diesel operation. The piston crown, skirt, and pin bore must match original equipment tolerances to prevent piston slap, oil consumption, and combustion-efficiency losses in engines typically found in commercial vehicles, marine installations, and industrial power units.

Material specification for OM352 replacement pistons in the aftermarket typically employs eutectic or hypereutectic aluminium-silicon alloy, with silicon content ranging 12-16 percent to improve wear resistance and reduce thermal expansion. The piston pin is usually a floating design with a hardened steel alloy, and ring grooves are machined to accept three piston rings: two compression rings and one oil-control ring. Standard industry practice includes anodising the top ring groove to resist micro-welding under high-temperature operation, and applying a graphite or molybdenum-disulphide skirt coating to reduce break-in scuffing. Typical weight for an OM352 piston is 800-1100 grams depending on whether it is a standard or oversized repair variant.

Buyers for this component include diesel engine rebuilders, commercial vehicle fleet maintenance operations, marine engine overhaul contractors, and aftermarket parts distributors serving African, Middle Eastern, and South American markets where OM352 engines remain in widespread service. The piston is relevant for both naturally aspirated and turbocharged OM352 builds, though compression ratios and crown configurations differ between these applications. Importers should confirm with Cnflap Engine Parts (GZ) Ltd. whether the supplied piston is cast, forged, or hypereutectic, and whether it is supplied with piston rings, wrist pin, and circlips as a kit or as the bare piston only.

Cnflap Engine Parts (GZ) Ltd. is registered at Room 2307, South Tower B, The Hub, 1068 East Xingang Road, Guangzhou 510308, China. The supplier holds an 'imported' tier and 'harbor' trust classification, with a zero percent response rate and no average response hours recorded. This profile suggests limited platform-mediated communication history, so buyers should obtain direct contact details and confirm availability of English-speaking technical staff before placing orders.

The company's location in Guangzhou places it within Guangdong Province's automotive components cluster, with access to port facilities at Huangpu or Nansha for containerised export. No manufacturing certifications, factory audit results, ISO registrations, or production capacity figures are disclosed in the available data. The listing does not state whether Cnflap Engine Parts operates a foundry and machining facility, or sources semi-finished pistons for final processing and distribution. Buyers should request a factory profile, quality-control documentation, and sample photographs with dimensional inspection reports before committing to volume purchases.
