Construction machinery For 374-0788 3740788 Crankshaft CAT Excavator C27 Engine Parts

Specification

Description

Advantage

Material Durability:Made of fatigue-resistant alloy, it has excellent wear and impact resistance, capable of withstanding stress shocks from long-term high-load operation of construction machinery.
Precision Compatibility:Strictly processed to match the assembly standards of the C27 engine, with minimal installation gap error, it can be directly adapted to the equipment without additional debugging.
Structural Stability:Optimized balance weight layout and surface-hardened journals effectively reduce vibration and noise during operation, improving the smoothness of power transmission.
Scenario Adaptability:Designed specifically for heavy excavators, it meets the continuous operation needs in complex working conditions such as mines and infrastructure, combining adaptability and reliability.

Performance

Load-Bearing Capacity:It can withstand the peak torque of the C27 engine under high-power output, with stable torque transmission without attenuation during continuous operation.
Operation Precision:The roundness and cylindricity errors of the main journals and connecting rod journals are controlled within 0.005mm, ensuring coaxiality and power transmission efficiency during high-speed operation.
Fatigue-Resistant Life:After professional fatigue testing, the service life under rated working conditions can reach more than 1.2 times the standard maintenance cycle of the equipment, reducing replacement frequency.
Temperature Adaptability:Within the operating temperature range of -20℃ to 120℃, there is no obvious change in material performance, suitable for engineering operations in different climatic environments.
