Connecting rod

Product Introduction

The connecting rod is a core transmission and load-bearing component inside the engine. Connecting to the piston pin at the upper end and fitted with the crankshaft connecting rod journal at the lower end, it transmits the reciprocating linear power of the piston to the crankshaft, completing the power conversion and output. Simultaneously, it withstands the combustion pressure and high-frequency reciprocating impact loads, making it a crucial component for engine force transmission and load bearing.

Made from a single piece of 40Cr alloy steel, it undergoes heat treatment, precision machining, and flaw detection. The rod body is highly resilient, resistant to bending and torsion. The large and small end holes are highly precise, wear-resistant, and do not deform. The standard clearance ensures even stress distribution, preventing breakage and bending. It is impact-resistant, fatigue-resistant, and its dimensions perfectly match original factory specifications, offering strong versatility. It is an essential part for engine overhauls.

Application Scenarios

• Construction Sites: For loaders with frequent loading and stopping, it smoothly transmits power and operates stably under alternating loads.
• Heavy-Duty Mining Conditions: For full-load climbing and heavy-load operations, it resists impact and deformation, and is not prone to failure during long-term operation.
• Sand and Gravel Yards, Coal Yards: For continuous full-load operation in all weather conditions, it resists fatigue wear and extends engine service life.
• Engine overhaul and maintenance: Suitable for replacing bent, deformed, worn, or broken connecting rods in various loader diesel engines.
• Complex and harsh working conditions: Suitable for high-temperature, high-frequency vibration environments in the engine compartment; structurally stable and durable.
