Buy & Import Connecting Rod Bearing Shells from Qinhuangdao Haixi Machinery Equipment Co., Ltd - Wholesale Supply

Connecting rod bearing shells from Qinhuangdao Haixi Machinery Equipment Co., Ltd are tri-metal plain bearings designed for heavy-duty diesel engines including L16/24, L20/70, L21/31, L23/30, L28/32, L27/38, and L32/40 series. Each shell features a steel backing for structural rigidity, a copper-lead intermediate layer for load distribution, and a babbitt overlay for wear resistance and embeddability of contaminants. These are supplied as complete sets per connecting rod position, matching OEM specifications for replacement and overhaul applications.

The tri-metal construction follows standard industry practices for high-load engine bearings, where the steel backing provides dimensional stability, the copper-lead alloy offers thermal conductivity and fatigue resistance, and the soft babbitt surface allows for micro-deformation under pressure to maintain oil film integrity. Typical thickness tolerances for such shells range from 0.05 mm to 0.15 mm across the bearing surface, with radial clearance designed to match crankshaft journal diameters in the 80 mm to 120 mm range. Surface finish is typically under 0.4 µm Ra to ensure optimal lubrication.

These bearings are used in marine propulsion systems, stationary power generators, and industrial reciprocating engines where continuous high-pressure operation demands reliability. Buyers in the shipping, energy, and heavy machinery sectors source these for engine rebuilds and maintenance cycles. Packaging includes rust-inhibited inner wraps and sealed cartons suitable for ocean freight. Trade terms are typically FOB Qinhuangdao, with minimum order quantities confirmed directly with the supplier.

Frequently Asked Questions About Connecting Rod Bearing Shells from Qinhuangdao Haixi Machinery Equipment Co., Ltd
The babbitt overlay follows ASTM B23 standards, typically composed of tin with 8-12% antimony and 1-3% copper. This composition ensures low friction and embeddability of debris under high load. Buyers should request a material certification for the overlay if compliance with ASTM B23 is required for their application.

Sourcing Connecting Rod Bearing Shells from Qinhuangdao Haixi Machinery Equipment Co., Ltd - China Import Guide

Before ordering, verify the exact engine model compatibility and confirm the bearing shell dimensions match your crankshaft journal diameter and connecting rod bore. Request a material certification for the babbitt and copper-lead layers, and ensure the thickness tolerance aligns with OEM specifications. Do not assume interchangeability with other brands without physical measurement or technical drawings.

Confirm the Incoterms, lead time, and packaging method directly with the supplier. FOB Qinhuangdao is typical, but shipping terms vary by order size. Lead times are not stated and may depend on production scheduling. Payment terms are usually T/T in advance or L/C at sight. Always request a commercial invoice and packing list that itemizes the bearing sets per engine model.

Perform visual inspection for surface defects, and check for consistent thickness across the bearing shell. Use a micrometer to verify thickness tolerance and a surface roughness gauge to confirm Ra ≤0.4 µm. Request a batch test report for hardness and adhesion if the application is critical. Retain samples for future reference in case of field failure.
