Overview

The 23B-15-13180 FLANGE KOMATSU is a high-strength, precision-engineered component designed for Komatsu heavy machinery, particularly in grader and loader assemblies. This essential part acts as a mounting and support interface that ensures perfect shaft alignment, smooth torque transfer, and consistent structural balance under heavy-duty operational stresses.

Manufactured by 3GEN Export, this 23B1513180 FLANGE KOMATSU meets the highest OEM quality standards. It is engineered to withstand the mechanical stress, vibration, and high-pressure environments of Komatsu transmission and powertrain systems. With tight machining tolerances and surface finishing that ensures optimal contact and fit, this flange guarantees superior performance and reliability in demanding working conditions.

Function and Application

The 23B-15-13180 FLANGE KOMATSU serves as a mechanical connector and stabilizer that links rotating elements such as shafts and housings in the drive or transmission assembly. It also provides an anchor point for bearings and seals, keeping components aligned while distributing stress evenly across the mounting surface.

Core Functions

• Shaft Alignment: Maintains perfect centering of drive shafts, preventing vibration or offset under torque load.

• Torque Transfer: Ensures smooth transmission of rotational power without loss or slippage.

• Bearing Support: Houses and secures bearings for stable rotation of connected elements.

• Vibration Damping: Reduces mechanical resonance and distributes forces evenly.

• Structural Sealing: Provides a tight interface to prevent oil leakage or ingress of dust and debris.

By securing the rotational assembly within the transmission or axle housing, this flange improves operational reliability and extends the lifespan of the machine’s entire drive system.

Design and Construction

1. Material Composition

The 23B-15-13180 FLANGE KOMATSU is manufactured from high-grade ductile cast iron reinforced with carbon and manganese additives for superior tensile strength. The inner bearing seat is precision-machined and hardened to maintain wear resistance even under continuous frictional stress.

• Material: Ductile Iron (Grade 500–7)

• Surface Treatment: Anti-corrosive coating and phosphate layer for rust resistance

• Machining Process: CNC lathe finishing with surface tolerance of ±0.01 mm

This alloy composition and finishing combination ensures both mechanical durability and dimensional stability over time.

2. Surface Coating

The flange is coated in Komatsu’s signature industrial-grade yellow enamel, enhancing corrosion resistance and aiding visual inspection. Beneath the coating lies a metallic layer treated with anti-oxidation primers that resist harsh environmental factors such as humidity, mud, and hydraulic oil exposure.

3. Structural Reinforcement

The flange body is designed with reinforced ribs along the mounting plane to reduce deformation during high-torque operations. Its uniform wall thickness ensures even heat dissipation, which prevents thermal expansion and cracking.

Technical Specifications

Compatibility with Komatsu Models

The 23B-15-13180 FLANGE KOMATSU is compatible with a wide range of Komatsu graders, wheel loaders, and construction vehicles. Each application ensures high torque support and vibration control in the drive and axle assemblies.

The flange fits directly into Komatsu’s transmission, differential, and drive systems, ensuring full compatibility without modification. Its bolt-hole configuration matches OEM standards, allowing easy replacement during maintenance or rebuilds.

Precision Manufacturing Process

Forging and Machining

Each 23B-15-13180 FLANGE KOMATSU undergoes a controlled forging process that ensures internal grain alignment and eliminates voids in the material. After forging, CNC machines cut the mounting holes and inner bearing seat with micron-level precision.

Heat Treatment

Following machining, the flange is heat-treated using a controlled quenching process that increases its surface hardness to 48–52 HRC while keeping the inner structure flexible enough to absorb torque vibrations.

Dimensional Verification

Every flange passes through a coordinate measuring machine (CMM) verification stage. This ensures that the inner bore and bolt pattern are perfectly concentric, eliminating the risk of misalignment during installation.

Performance Features

1. Load-Bearing Strength

Capable of sustaining heavy radial and axial loads, the 23B-15-13180 FLANGE KOMATSU resists deformation under extreme torque stress. This is particularly important in graders and loaders where hydraulic power transfer is continuous.

2. Anti-Vibration Design

The precise bolt pattern and symmetrical geometry of this flange help dissipate vibrations evenly throughout the mounting base, protecting bearings and shafts from premature wear.

3. Corrosion and Temperature Resistance

The protective coating and metallic treatment offer resistance against water, mud, dust, and oil contamination. The component retains its mechanical integrity in temperature ranges from –40°C to +180°C.

4. Seamless Installation

With its pre-threaded bolt holes and smooth inner bore, the 23B-15-13180 FLANGE KOMATSU allows for effortless installation and alignment with existing drive assemblies.
