Rammer R Series Bushing Set | Inner Bush and Outer Bush for Hydraulic Breaker

Rammer R Series Bushing Set for Hydraulic Breaker Tool Guidance and Wear Protection

The Rammer R Series Bushing Set includes Inner Bush and Outer Bush, which are essential wear components designed for Rammer R Series hydraulic breakers. These bushings support the working tool, maintain accurate chisel alignment, and protect the hydraulic breaker housing from excessive wear during operation.

During hydraulic breaker working cycles, the chisel experiences continuous high-frequency impact and side loading. Without proper bushing support, excessive movement between the tool and breaker body can occur, leading to uneven wear, reduced impact efficiency, and possible damage to internal components.

Our Rammer R Series Inner Bush and Outer Bush are manufactured from wear-resistant alloy steel with precision machining and professional heat treatment processes. Each bushing is produced according to OEM specifications to ensure accurate dimensions, excellent hardness, and stable performance under demanding working conditions.

Designed for Rammer R Series hydraulic breakers, our replacement bushing sets provide a reliable solution for equipment distributors, repair workshops, contractors, and hydraulic breaker users who require durable aftermarket components.

Product Features

Wear-Resistant Alloy Steel Material

The Rammer R Series Bushing Set is manufactured from specially selected alloy steel, providing excellent resistance to impact, friction, and continuous wear.

Precision Machined Dimensions

Advanced CNC machining ensures accurate inner and outer dimensions, allowing proper clearance and smooth movement between the chisel and bushing.

Professional Heat Treatment

Optimized heat treatment improves hardness, toughness, and wear resistance for long-term operation.

Improved Tool Alignment

The inner and outer bushes maintain correct chisel positioning, reducing vibration, abnormal movement, and uneven wear.

Protection of Hydraulic Breaker Housing

The bushings act as a protective wear surface, reducing direct contact damage between the working tool and breaker body.
