Why Do box type silenced hydraulic breaker Adopt Extended Outer Bushings? Professional Answers from Zhengzhou Hanyun!
Release time：2026年1月23日
In the structure of a hydraulic breaker, the outer bushing is a vital core component, especially critical for box-type silenced hydraulic breakers. Recently, many clients have asked us: why do the customized box-type breakers we provide use extended outer bushings? Today, Zhengzhou Hanyun will give you a detailed explanation.
The outer bushing is the working area where intense impact occurs between the chisel and piston, enduring high-speed and high-frequency impact loads. If the outer bushing is too short, the impact points between the piston and chisel are prone to eccentricity or offset during long-term use, leading to uneven impact force. This in turn causes the following problems:
HanYun Hydraulic Breakers: Setting Standards Inspired by Epiroc Breakers
- Accelerated wear on the piston head
- Local damage to the chisel tail
- Rapid loosening or fracture of the outer bushing
- Reduced overall service life of the hydraulic breaker
The extended outer bushing design can effectively guide the chisel and piston to move precisely along the same axis, significantly reducing the risk of impact offset. It structurally protects the chisel, piston and bushing, and enhances the overall stability and service life of the breaker.
