23B1513610 , 23B-15-13610 COLLAR KOMATSU

Overview

The 23B-15-13610 COLLAR KOMATSU is a precision-machined mechanical component designed to provide structural alignment and rotational stability in Komatsu’s heavy-duty equipment systems. Built to withstand extreme mechanical stress, this collar functions as a supporting and locking interface between shafts, pins, and housings, ensuring smooth torque transmission and minimizing vibration during operation.

Produced and supplied by 3GEN Export, this part exemplifies the company’s reputation for delivering OEM-level engineering quality with global availability. Every 23B1513610 COLLAR KOMATSU undergoes multi-stage testing for concentricity, hardness, and dimensional accuracy, guaranteeing a perfect fit and consistent performance in the demanding environments that define Komatsu machinery.

Function and Role in Komatsu Machinery

The collar acts as a rotational and positioning interface that secures shafts, pins, or bearings in their designated locations. Its robust steel structure and precision-ground interior provide both mechanical strength and alignment accuracy.

Primary Functions

• Shaft Positioning: Keeps shafts centered and stable during rotation.

• Load Transfer: Distributes axial and radial forces evenly to prevent localized stress.

• Vibration Control: Reduces oscillation and mechanical noise.

• Lubrication Path Support: Facilitates consistent lubrication through internal channels or oil holes.

• Locking and Alignment: Works with keyways and retaining fasteners to prevent unwanted displacement.

When installed in Komatsu drive trains, hydraulic actuators, or pivot assemblies, the 23B-15-13610 COLLAR KOMATSU provides the precision necessary to maintain machinery alignment and operational balance, especially under constant vibration and load shifts.

Engineering Design and Construction

Material Composition

The 23B-15-13610 COLLAR KOMATSU is engineered from alloyed tool steel, chosen for its toughness, dimensional stability, and resistance to wear. The part’s interior and exterior surfaces are ground to a mirror-smooth finish, reducing friction and ensuring uniform motion.

• Material: Heat-treated alloy steel (42CrMo4 / SAE 4140 equivalent)

• Surface Hardness: 50 – 55 HRC

• Coating: Micro-phosphate anti-corrosive layer

• Finish: Fine-ground inner bore with high-polish edge radius

• Manufacturing Standard: CNC-machined to ISO 9001 and JIS B 8354 tolerances

This manufacturing approach ensures consistent performance under high mechanical stress and resistance to long-term fatigue.

Dimensional Integrity

The collar’s dimensions are controlled within ±0.01 mm. The inner bore, keyway groove, and oil port are precisely aligned, supporting seamless integration with Komatsu’s shafts and pins.

Approximate Dimensions:

• Outer Diameter: 65 mm

• Inner Diameter: 45 mm

• Height: 40 mm

• Weight: 0.28 kg

These proportions make the 23B1513610 COLLAR KOMATSU a compact yet essential structural component that delivers both accuracy and endurance.

Technical Specifications

Compatibility with Komatsu Models

The 23B-15-13610 COLLAR KOMATSU fits a broad range of Komatsu earthmoving and construction machines, ensuring accurate fitment in original assemblies.

Compatible Models Include:

• Komatsu WA470-5 / WA470-6 / WA470-8 Wheel Loaders

• Komatsu GD655-5 / GD675-6 Motor Graders

• Komatsu PC300-7 / PC350 Excavators

• Komatsu D155AX-7 / D155A-6 Bulldozers

• Komatsu HM300 / HM400 Articulated Trucks

• Komatsu HD465 Rigid Dump Trucks

Each application uses the collar to lock drive-shaft or pin assemblies, maintaining alignment in rotating or pivoting components subject to variable torque.

Manufacturing Process

Step 1 – Forging

A high-density billet of alloy steel is hot-forged to refine the grain structure. This step enhances fatigue resistance and impact strength.

Step 2 – CNC Machining

The forged blank is CNC-turned, drilled, and bored to final geometry. Precision machining of the inner bore and key slot ensures a seamless mechanical interface.

Step 3 – Heat Treatment

The collar undergoes controlled hardening and tempering. This gives the inner surface the required wear resistance while keeping the core slightly ductile.

Step 4 – Grinding and Polishing

A multi-stage grinding process refines the inner diameter to achieve mirror-like smoothness and reduces friction during operation.

Step 5 – Coating and Inspection

Finally, the surface receives a phosphate coating to prevent corrosion. Every collar is laser-measured for diameter, concentricity, and run-out deviation before packaging.

Performance Advantages

1. Exceptional Durability – The high-strength steel construction resists deformation even under repeated shock loads.

2. Perfect Alignment – CNC precision ensures accurate centering within Komatsu mechanical systems.

3. Reduced Friction – Polished inner bore minimizes wear between shaft and collar.

4. Extended Service Life – The corrosion-resistant coating prolongs usability even in moisture-rich environments.

5. Universal Compatibility – Its dimensional tolerance makes it compatible with multiple Komatsu assemblies.

6. Cost Efficiency – Longer operational life and reduced maintenance costs result in higher overall value.

Application and Use Cases

The 23B-15-13610 COLLAR KOMATSU is used wherever shafts or pins must remain fixed against axial movement while rotating under load.

Typical Applications

• Hydraulic Cylinder Mountings – Acts as a retaining and sealing element.

• Transmission Housings – Aligns drive shafts and keeps bearings locked.

• Swing Frames and Boom Joints – Prevents lateral displacement.

• Final Drive Systems – Balances torque distribution in differential components.

Its compact design allows easy replacement without requiring extensive disassembly, which reduces downtime for maintenance teams.
