Product Specification

Rammer E Series Bushing Set for Hydraulic Breaker Chisel Guidance and Wear Protection

The Rammer E Series Bushing Set includes Inner Bush and Outer Bush, which are essential wear components designed for Rammer E Series hydraulic breakers. These bushings provide stable guidance for the working tool, maintain proper chisel alignment, and protect the hydraulic breaker front head from excessive wear during continuous impact operation.

During construction, mining, and demolition applications, hydraulic breakers experience repeated high-frequency impacts and side loads. The bushing system supports the chisel and reduces direct friction between the working tool and breaker body. Properly maintained bushings help improve impact efficiency, reduce vibration, and extend the service life of other hydraulic breaker components.

Our Construction Rammer E Series Inner Bush and Outer Bush are manufactured from wear-resistant alloy steel with precision machining and professional heat treatment. Each bushing is produced according to OEM-compatible dimensions to ensure accurate fitting, stable performance, and reliable durability in demanding working environments.

Designed for Rammer E Series hydraulic breaker hammers, our replacement bushing sets are widely used by hydraulic breaker distributors, repair workshops, construction contractors, and equipment owners for maintenance and rebuilding applications.

Product Features

Wear-Resistant Alloy Steel Material

The Rammer E Series Bushing Set is manufactured from high-strength alloy steel, providing excellent resistance against:

• Impact loads
• Friction wear
• Deformation
• Continuous working stress

This ensures stable performance during long-term hydraulic breaker operation.

Precision Machined Dimensions

Advanced CNC machining technology ensures:

• Accurate inner diameter
• Correct outer diameter
• Proper clearance with chisel
• Smooth tool movement

Precision dimensions help reduce abnormal wear and improve breaker efficiency.

Professional Heat Treatment

Special heat treatment processes improve:

• Surface hardness
• Material toughness
• Wear resistance
• Service life

Allowing the bushing to withstand high-frequency impact conditions.

Improved Chisel Alignment

The inner bush and outer bush maintain the correct position of the working tool, reducing:

• Chisel vibration
• Side movement
• Uneven wear
• Front head damage

Protection of Hydraulic Breaker Housing

The bushing acts as a replaceable wear surface, protecting expensive internal breaker components from direct tool contact.

OEM-Compatible Replacement

Manufactured according to OEM specifications for direct replacement on Rammer E Series hydraulic breakers.
