21N-70-14140 Adapter-Weld on-Bevel for Komatsu PC1000 | Heavy-Duty Alloy Steel Construction

Product Overview

The 21N-70-14140 Adapter-Weld on-Bevel (BYP161147) is a heavy-duty weld-on component specifically engineered for Komatsu PC1000 excavators operating in extreme mining and quarrying conditions. this adapter effectively distributes stress and protects the bucket lip structure while ensuring secure attachment of compatible teeth. Manufactured from premium alloy steel, it delivers exceptional durability and reliability in the most demanding applications.

Key Features & Benefits

• Advanced Stress Distribution: The gap design effectively absorbs and disperses impact forces, significantly reducing stress concentration on the bucket lip and extending its service life

• Superior Material Strength: Forged from high-grade alloy steel and treated with quenching and tempering heat treatment, achieving optimal hardness (350-420 HB) for maximum wear resistance and impact strength

• Precision Weld-On Construction: Designed for seamless integration with Komatsu PC650, PC650SE, PC710, PC710SE  bucket lips, ensuring perfect alignment and eliminating bolt-related failure points

• Extended Component Life: Robust construction and specialized heat treatment provide up to 40% longer service life compared to standard adapters in abrasive conditions

• Cost-Efficient Operation: Reduces bucket lip wear and replacement frequency, significantly lowering overall operating costs and maintenance downtime
