Product Description

Outer Bush Lower Bush Front Cover For  Hydraulic Hammer Rock Road Breaker Apply To Excavator 


Product Introduction

Guchuan Machinery provides heavy-duty hydraulic breaker outer bushing precision-engineered from premium 42CrMo and 40Cr alloy steels. Specifically designed for maximum durability on critical models like the SB81, SB121, SB131, SB151, HB20G, HB30G, and HB40G, these bushings deliver superior impact resistance and fatigue strength. They are engineered to withstand extreme stress, drastically reduce downtime, and extend the service life of your equipment in the most demanding demolition and mining applications.


Key Features

  1. High-Quality Materials: Made from durable steel, these parts are designed to withstand harsh working conditions and provide long-lasting performance.
  2. Precision Engineering: The outer bush, lower bush, and front cover are manufactured with precision to ensure a perfect fit and smooth operation.
  3. Easy Installation: These parts are designed for easy replacement, reducing downtime and maintenance costs.


Applications 

  • Road Construction and Maintenance: Breaking asphalt and concrete during road repairs and new construction.
  • Mining and Quarrying: Efficiently breaking rocks and ores in mining operations.
  • Demolition Projects: Ideal for breaking down structures and clearing debris.




Why 42CrMo and 40Cr?
Both 42CrMo and 40Cr are industry-respected materials for critical mechanical parts, especially in mining and construction equipment. The key differentiator is the addition of molybdenum in 42CrMo. This element significantly enhances the steel's hardenability, strength at high temperatures, and most importantly, its resistance to fatigue and impact—making it the premier choice for the largest and most powerful breakers.
