Alloy Steel Rock Breaker Bushing 42CrMo Hydraulic Hammer Inner Sleeve Excavator Breaker Spare Parts

Brief Introduction

Our hydraulic breaker bushing is precision CNC machined alloy steel spare part for excavator rock hammer. With professional heat treatment, it features excellent wear resistance and impact resistance, protecting the hydraulic breaker under heavy impact working conditions. OEM & custom machining service is available, factory direct supply with stable quality.

Product Overview

This hydraulic breaker inner bushing is a core wear-resistant component of rock breakers. It is processed by high-precision CNC turning and milling, paired with strict heat treatment to improve hardness and toughness. The bushing acts as a buffer and friction-reducing part between the piston and hammer shell, absorbing huge impact force during rock breaking, mining and demolition work, reducing wear of the main machine and extending the service life of the hydraulic breaker.

All products are inspected one by one before delivery to guarantee precise dimension tolerance and stable performance. We can manufacture according to your drawings or samples for non-standard specifications.
