7077635010 , 707-76-35010 BUSHING KOMATSU

Premium Hydraulic Cylinder Bushing for Komatsu Equipment

The 7077635010 BUSHING KOMATSU is a precision-machined steel component designed to deliver maximum stability, alignment, and durability within the hydraulic cylinder assemblies of Komatsu heavy machinery. Built for extreme load-bearing applications, it ensures smooth articulation between the cylinder rod and housing—minimizing wear, vibration, and misalignment under continuous mechanical stress.

Manufactured and supplied by 3GEN Export, this bushing exemplifies OEM-grade craftsmanship and reliability. Engineered from high-strength alloy steel and finished with advanced surface treatments, it provides exceptional resistance to abrasion and impact, guaranteeing prolonged service life in the toughest construction, quarry, and mining operations worldwide.

Precision Engineering for Long-Term Performance

Every 707-76-35010 BUSHING KOMATSU undergoes a multi-stage machining and heat-treatment process to achieve the tight tolerances required for Komatsu hydraulic cylinders. The component is ground to micrometric accuracy, ensuring a perfect interference fit that enhances hydraulic performance, maintains shaft alignment, and reduces the risk of oil leakage.

This bushing’s spherical internal profile allows angular motion while absorbing radial and axial loads, ensuring consistent movement of cylinder components. The integrated lubrication hole supports proper grease distribution, preventing metal-to-metal contact even under high friction.

Technical Specifications

Compatible Komatsu Models

The 707-76-35010 BUSHING KOMATSU is compatible with a wide range of Komatsu hydraulic systems, including excavators, bulldozers, and loaders that utilize spherical or cylinder-mount bushings for motion absorption and load distribution.

Commonly Used in Models:

• Komatsu PC200-6 / PC200-7 / PC200-8 Excavators

• Komatsu PC210-8 / PC220-8 Hydraulic Excavators

• Komatsu PC300-7 / PC300-8 Medium Excavators

• Komatsu D65EX / D85EX Bulldozers

• Komatsu WA200 / WA250 Wheel Loaders

Due to its robust design and material compatibility, the 707-76-35010 BUSHING KOMATSU is also interchangeably used across several cylinder assemblies, providing mechanics with flexibility and reduced maintenance costs.

Material Technology and Design

Heat-Treated Alloy Steel Construction

The 707-76-35010 BUSHING KOMATSU is produced from chromium-molybdenum alloy steel, chosen for its high yield strength and ability to resist deformation under stress. Each bushing is case-hardened through controlled induction heating to provide a tough, wear-resistant outer surface while maintaining a ductile core for shock absorption.

This microstructural balance ensures that even in high-pressure hydraulic environments, the bushing retains dimensional accuracy, preventing premature wear of both the bushing and mating parts.

Phosphate Surface Coating

The dark, corrosion-resistant finish visible on the component results from a manganese-phosphate coating. This coating improves surface hardness, enhances oil retention, and prevents rust formation, making the 707-76-35010 BUSHING KOMATSU ideal for long-term outdoor exposure.

Spherical Profile for Multi-Directional Movement

The internal ball-joint geometry of this bushing provides rotational flexibility across multiple axes. It absorbs misalignments between hydraulic components, reducing stress on piston rods and bearings while maintaining perfect mechanical symmetry.

Functional Advantages

The 707-76-35010 BUSHING KOMATSU plays a key role in maintaining the mechanical harmony of Komatsu hydraulic systems.

Primary Functions

• Load Distribution: Evenly spreads hydraulic force across the joint surface.

• Vibration Damping: Minimizes shock impact during operation in rough terrain.

• Alignment Retention: Ensures accurate rod and housing alignment.

• Wear Prevention: Reduces friction and surface scoring.

• Seal Protection: Maintains proper pressure alignment, protecting seals and cylinders.

Key Benefits

• Increased machine stability and smoother operation.

• Extended life span for hydraulic cylinders and connecting pins.

• Resistance to moisture, dirt, and abrasive particles.

• Reduced frequency of component replacement.

Installation and Maintenance

The 707-76-35010 BUSHING KOMATSU is designed for quick and secure installation without complex tooling.

Installation Steps:

1. Clean the mounting bore and rod surface thoroughly.

2. Verify bore dimensions and alignment before press-fitting.

3. Apply a thin layer of assembly grease to the bushing inner surface.

4. Insert the bushing carefully using a hydraulic press or soft driver tool.

5. Confirm the lubrication hole alignment with the grease port.

6. After installation, inject grease to verify flow through the bushing.

Maintenance Tips:

• Regularly inspect for wear marks or loosening.

• Keep bushings properly lubricated with hydraulic grease.

• Replace in pairs to maintain uniform wear.

• Store unused bushings in a dry environment to avoid oxidation.

Following these steps ensures optimal fit and maximized service life of the 707-76-35010 BUSHING KOMATSU.

Applications in Komatsu Machinery

This bushing is used in multiple motion-critical assemblies, including:

• Boom and Arm Joints: To stabilize linkage movement under pressure.

• Hydraulic Cylinder Ends: To absorb axial loads from piston movement.

• Swing and Articulation Points: To reduce vibration and increase smoothness of rotation.

• Steering and Tilt Systems: To preserve hydraulic alignment and force balance.

Its versatile geometry makes the 707-76-35010 BUSHING KOMATSU essential for both front and rear joint assemblies across excavators, dozers, and loaders.
