Daemo DMB Standard Series Front Head Back Head For Breaker Hammer Repair

Product Introduction

The Daemo DMB Standard Series Front Head / Back Head is designed for excavator-mounted hydraulic breaker hammers used in demolition, quarrying, mining, road construction, trenching, concrete breaking, and heavy-duty rock breaking applications. It is suitable for Daemo DMB Standard Series hydraulic breakers, including common models such as DMB50, DMB70, DMB90, DMB140, DMB180, DMB210, DMB220, DMB230, DMB250, DMB300, DMB360, and DMB450.

The front head and back head are important structural parts of a hydraulic breaker hammer. The front head supports the chisel, bushings, retaining pins, and working tool system. It helps guide the breaker chisel during impact operation and protects the internal structure from excessive movement and wear. The back head is located at the upper part of the breaker and is connected with the nitrogen chamber and main body system. It plays an important role in supporting hydraulic breaker impact performance and structural stability.

When the front head or back head becomes cracked, worn, deformed, or damaged by long-term impact, the hydraulic breaker may show abnormal vibration, weak impact, oil leakage, nitrogen leakage, tool shaking, or unstable working frequency. Replacing damaged head parts in time can help restore breaker performance and reduce further damage to the cylinder, piston, bushing, chisel, seal kit, and through bolts.

This product is an aftermarket replacement front head and back head compatible with Daemo DMB Standard Series hydraulic breakers. The Daemo and DMB model names are used only for compatibility reference.

Product Features

Our Daemo DMB Standard Series front head and back head are produced for high-impact hydraulic breaker working conditions. These parts need strong structural strength, accurate machining, and reliable fitting tolerance because they are installed in key positions of the breaker hammer assembly.

The front head must match the chisel diameter, inner bush, outer bush, retaining pin, and lower breaker body. Accurate dimensions help ensure smooth tool movement and stable impact energy transfer. If the front head is worn or out of tolerance, the chisel may move abnormally, causing faster wear on bushings, pin holes, and the tool itself.

The back head needs good sealing and fitting performance. It is closely related to the nitrogen chamber and hydraulic breaker upper structure. A properly produced back head can help maintain stable pressure support, reduce leakage risk, and improve the overall working condition of the breaker.

The parts can be produced from selected alloy steel or customer-specified material according to model, working condition, and order requirements. CNC machining, heat treatment, drilling, boring, grinding, and surface finishing are used to achieve accurate fitting and stable performance.

Main Advantages

The main advantage of the Daemo DMB Standard Series front head and back head is their ability to restore hydraulic breaker structure and working stability. For repair workshops and spare parts distributors, these parts are important replacement components for breaker rebuild projects and heavy repair work.

A properly matched front head can reduce chisel shaking and protect the bushing system. It also helps maintain better impact direction, which is important for demolition, concrete breaking, road repair, trenching, quarrying, and mining work. When the front head is in good condition, the breaker tool can work more smoothly and efficiently.

A properly matched back head helps support the breaker’s upper structure and pressure system. It can reduce the risk of abnormal leakage and unstable impact performance. For heavy-duty hydraulic breakers working under continuous impact, reliable head parts are essential for long-term operation.

Replacing damaged front head or back head parts in time can also reduce maintenance costs. If the damaged part continues to be used, it may cause secondary damage to the piston, cylinder, seal kit, through bolts, bushings, and chisel. Timely replacement is an effective way to protect the whole hydraulic breaker assembly.
