Mechanical Function and Design Purpose

The 2327053140 BUSHING KOMATSU is engineered to sustain heavy axial and radial loads, serving as the primary wear-resistant sleeve that ensures controlled movement in pivot joints. It acts as a buffer between components such as the boom, arm, and bucket linkage, allowing rotational motion while minimizing friction and metal-to-metal contact.

Core Functional Benefits:

• Distributes operational loads evenly across the joint assembly.

• Reduces vibration and mechanical shock during heavy digging operations.

• Maintains precise alignment of moving components under high torque.

• Protects shafts, pins, and bores from direct abrasion.

• Ensures long-term stability of linkage mechanisms.

Its internal lubrication hole enhances grease flow and retention, minimizing maintenance intervals and ensuring consistent lubrication across the working surface.

Material Composition and Durability

The 232-70-53140 BUSHING KOMATSU is made from an advanced alloy steel that has undergone multiple treatment phases — including forging, quenching, and tempering — to enhance wear resistance and load capacity.

Engineering Features:

• Forged Alloy Steel: Ensures superior tensile strength and deformation resistance.

• Hardened Surface Layer: Provides long-lasting wear resistance in abrasive conditions.

• Tough Core: Maintains ductility to absorb impact without cracking.

• Precision Ground Finish: Guarantees minimal friction and smooth motion.

• Lubrication Groove & Hole: Facilitates optimal grease distribution.

This combination of metallurgical excellence and design precision allows the 2327053140 BUSHING KOMATSU to perform efficiently in harsh working conditions, from quarry sites to large-scale construction projects.
