Product Features

• Structure: A precision-machined, hollow cylindrical bushing made from high-strength copper-lead alloy or aluminum-tin alloy, with an oil feed hole for lubrication.

• Performance: Provides a low-friction bearing surface for the piston pin, distributing loads evenly and preventing wear on both the connecting rod and piston pin. The oil feed hole ensures continuous lubrication to reduce heat and friction.

• Design: Directly interchangeable with original equipment bushings, ensuring a precise interference fit in the connecting rod small end for reliable operation.

Core Function

1. Load Distribution: Transmits the combustion forces from the piston pin to the connecting rod, distributing stress evenly to prevent localized wear.

2. Lubrication: The oil feed hole channels engine oil to the piston pin and bushing interface, reducing friction and heat generation.

3. Wear Protection: The alloy construction resists fatigue and wear, extending the service life of both the connecting rod and piston pin in harsh operating conditions.

Frequently Asked Questions – Bearing C02FL-7M4046+A SHANGCHAI

What engine models does the Bearing C02FL-7M4046+A fit?

This bearing is engineered for SHANGCHAI SC-series diesel engines. It matches the original equipment dimensions and clearance specifications used in SC9D, SC12E, and related engine platforms. Always cross-reference with your engine serial number to confirm fitment.

Is the Bearing C02FL-7M4046+A a main bearing or connecting rod bearing?

The C02FL-7M4046+A part number corresponds to a specific position within the SHANGCHAI engine bearing set. Contact our technical team with your engine model number, and we will confirm the exact application position and whether you need a matched set.

What material is used in this bearing, and how does it affect longevity?

This bearing uses a multi-layer construction — typically a steel backing for structural rigidity, an intermediate copper-lead or aluminum-tin alloy layer for load distribution, and a soft overlay for conformability and embedability. This design allows the bearing to absorb minor shaft imperfections and contaminants without scoring, extending service life significantly under proper lubrication.

How tight are the dimensional tolerances on this bearing?

Wall thickness tolerance is controlled to ±0.01 mm, and bore diameter conformance meets OEM blueprint specifications. Each production batch undergoes CMM (Coordinate Measuring Machine) verification to ensure consistency across units.

Can I order this bearing with custom packaging under my own brand?

Yes. METTLEAD supports white-label and fully custom packaging solutions. You provide the artwork and specifications, and we deliver bearing sets ready for your distribution channel — no minimum design fees on qualifying order quantities.

What is the recommended replacement interval for this bearing?

Replacement intervals depend on operating conditions, oil quality, and maintenance practices. Under normal operating conditions with proper filtration and oil change schedules, SHANGCHAI engine bearings typically perform reliably for 300,000–500,000 km. Inspect during major overhauls or if oil analysis indicates elevated copper or lead content.
