Import Benz Engine Parts Benz Piston Ring — Buy in wholesale FOB from Supplier in China

Zhejiang Landemake Auto Parts Co., Ltd. manufactures piston rings for Mercedes-Benz OM series diesel engines, with explicit dimensional data for the OM457 and OM501LA applications among others. The source lists a 128 mm diameter by 3.5 plus 3.5 plus 3.5 plus 6.5 mm axial width configuration for the OM355/OM346 engine family, with alternative geometries available across a catalogue exceeding 1,000 part numbers. Material options span nodular cast iron, alloyed cast iron and steel, with surface treatments including gas nitriding, chrome plating, phosphating and oxidation to match specific cylinder liner compatibility and duty cycle requirements.

The axial width stack (compression rings plus oil control ring) dictates ring tension, oil consumption and blow-by control. For the OM457 heavy-duty application at 128 mm bore, the 3-3-4 mm stack (two compression rings, one oil ring) represents a modern reduced-friction design compared with the older 3.5-3.5-3.5-6.5 mm four-ring layout of the OM355. Nodular iron offers superior thermal fatigue resistance for turbocharged intercooled engines, while steel top rings with PVD or chrome-ceramic coatings withstand peak cylinder pressures above 180 bar in contemporary common-rail diesels. Landemake states adaptability to high rotation speeds and high loads, though buyers should request specific test data for ring flutter limits and end-gap growth at elevated temperatures.

These piston rings target engine rebuilders, commercial vehicle fleet workshops and aftermarket distributors serving European truck parc in Africa, the Middle East and Southeast Asia where Mercedes-Benz OM engines remain prevalent. The supplier also produces water pumps, offering potential basket consolidation for overhaul kit suppliers. Packaging is stated as plastic bag and white box with customer-specific options available. No minimum order quantity, price band or lead time is disclosed in the source; buyers must negotiate directly. The harbour trust tier and zero response rate signal the need for proactive follow-up and possibly third-party factory verification before commitment.

Zhejiang Landemake Auto Parts Co., Ltd. is situated at No.30 Huancheng West Road, Pingyang, Wenzhou, Zhejiang Province 325400, China. The Wenzhou region carries a dense concentration of automotive component manufacturers, particularly in precision castings and machining. The supplier holds a harbour trust tier with no response rate or average response hour data, indicating a registered profile without demonstrated communication history on the platform. Buyers should treat this as an initial contact requiring standard vendor qualification procedures.

The company claims a catalogue exceeding 1,000 piston ring varieties and capability to develop custom specifications, alongside water pump production. No founding year, employee count, factory floor area, annual turnover, OEM customer names or independent audit references appear in the source. The extensive engine coverage list suggests either substantial pattern inventory or flexible manufacturing, but this should be validated through factory visit or video audit. Request evidence of ring groove contact pattern testing, material certification from the cast iron foundry, and traceability records for heat treatment batches before accepting first production.
