The 23B-27-11563 STUD BALL KOMATSU is a precision-machined load-bearing component designed to deliver stability, flexibility, and durability to the boom and arm joints of Komatsu heavy machinery. By absorbing multidirectional loads and ensuring smooth pivot motion, this stud ball supports hydraulic articulation under the toughest excavation and mining conditions.
Developed with exact dimensional accuracy, the 23B2711563 STUD BALL KOMATSU helps maintain structural integrity and alignment in linkage assemblies. Manufactured from hardened alloy steel and polished to a mirror finish, it performs with maximum endurance under continuous vibration and impact.
As a trusted OEM-grade part, 3GEN Export supplies this stud ball to Komatsu users worldwide—offering reliable quality, strict tolerance control, and global delivery in only five working days.
The 23B-27-11563 STUD BALL KOMATSU functions as a spherical connection element linking the moving arms of the machine’s boom system. It allows for controlled motion while transmitting forces between structural components.
The upper section features a precision-formed spherical head, while the lower shank is cylindrical with an internally threaded bore. This configuration permits exact mounting with bolts or retaining pins, achieving both rotational and axial security inside the housing.
Each stud ball is CNC-machined to sub-millimeter precision and undergoes heat treatment to balance hardness with flexibility. The polished ball surface ensures reduced friction against the socket or bushing, minimizing wear and enhancing long-term reliability.

Within Komatsu’s heavy-duty equipment, the 23B-27-11563 STUD BALL KOMATSU provides a flexible spherical joint between boom and linkage assemblies. Its role is to:
Allow multi-axis movement without mechanical distortion
Distribute stress evenly across pivot points
Reduce vibration and fatigue in the arm assembly
Maintain perfect alignment under hydraulic load
When used in excavators or wheel loaders, this stud ball’s polished geometry and load rating protect the surrounding bushings, sockets, and seals from uneven wear—ensuring extended operational uptime.
CNC machining guarantees consistent radius curvature and concentricity. The precision profile keeps rotational torque uniform, preventing uneven pressure and joint noise.
Through controlled induction hardening and tempering, the component reaches surface hardness of 58–62 HRC, providing resistance against abrasive dust and hydraulic shock.
Unlike externally threaded designs, the internal thread of the 23B-27-11563 STUD BALL KOMATSU ensures cleaner aesthetics, easier torque application, and enhanced tensile strength during installation.
A two-layer coating—zinc phosphate primer and sealing film—protects against rust even after thousands of operating hours in humid environments.
Surface roughness (Ra < 0.05 µm) ensures minimal friction, improving efficiency and lowering energy loss in hydraulic systems.
The 23B-27-11563 STUD BALL KOMATSU is fully compatible with the following equipment:
Komatsu PC200-7 / PC200-8
Komatsu PC220-7 / PC220-8
Komatsu PC240LC-8
Komatsu PC270 and PC300 Series
Komatsu WA320 / WA380 Wheel Loaders
Komatsu D85EX-15 Dozers
Komatsu GD675 Grader Assemblies
This part integrates seamlessly with factory linkages without modification, maintaining OEM-level fitment and mechanical alignment.
Clean all socket bores and bushings. Remove debris and check for wear or distortion.
Position the stud ball so that the spherical head sits evenly within the bore. Ensure no gap exists between the flange and mounting surface.
Use a torque-calibrated wrench to tighten the bolt to the specified torque (typically 190 – 210 Nm). Avoid over-torquing.
Apply a thin layer of high-pressure grease on the ball surface before final assembly. Re-lubricate at regular intervals.
After installation, move the joint through its full range to confirm smooth motion and proper alignment.
High Structural Integrity: Supports extreme mechanical loads without deformation.
Extended Component Life: Reduces wear on bushings and pins.
Low Friction: Polished geometry ensures silent operation.
Corrosion-Proof: Protected against oxidation and humidity.
Plug-and-Play Compatibility: No modifications required for Komatsu equipment.
