High Compatibility OE-Quality Standard Optimized Oil Supply Design Crankshaft Bearing SET for Mitsubishi 4D34 6D34 Excavator Engine Parts

For ME999384 Crankshaft Bearing SET Mitsubishi 4D34 6D34 Excavator engine parts

Specification

Description

This crankshaft bearing set, part number ME999384, is specially designed for 4D34/6D34 series engines and serves as a core wear-resistant component for excavator engines. The complete set includes multiple bearings that fit the engine's main journals, featuring original equipment specifications for direct replacement installation. It effectively supports crankshaft rotation, reduces friction loss, and ensures stable engine operation.

Advantage

High Compatibility: Developed exclusively for 4D34/6D34 engines with precise dimensional tolerances, requiring no additional machining for direct replacement installation.
OE-Quality Standard: Made of high-performance bearing alloy materials, meeting the same specifications as original parts. It offers excellent wear resistance and fatigue resistance, ideal for high-intensity construction machinery applications.
Optimized Oil Supply Design: The bearing surface features well-designed oil grooves that ensure the formation of a lubricating oil film during crankshaft operation, minimizing dry friction and extending service life.
Complete Set Supply: The full set is fully equipped, eliminating the need for separate purchases. It meets engine overhaul or bearing replacement requirements, reducing procurement costs and installation errors.

Performance

Excellent Wear and Impact Resistance: The alloy bearings provide outstanding wear resistance and impact resistance, withstanding alternating loads under high engine speeds and heavy loads, reducing the risk of wear and bearing seizure.
Low Friction Loss: Precisely machined surfaces with low friction coefficients reduce engine operating resistance and improve fuel efficiency.
High Stability: High dimensional accuracy and optimal fit clearances ensure crankshaft coaxiality during operation, minimizing vibration and noise and extending engine overhaul intervals.
Long Service Life: Designed for harsh construction machinery environments, it offers high temperature and corrosion resistance, with a service life that meets the demands of long-term, high-intensity operation.
