Daemo DMB Standard Series Through Bolt Side Bolt For Hydraulic Breaker Parts

Product Introduction

The Daemo DMB Standard Series Through Bolt Side Bolt For Hydraulic Breaker Parts is an important fastening component used in excavator-mounted hydraulic breaker hammers. It is designed for the Daemo DMB Standard Series hydraulic breakers, including common models such as DMB50, DMB70, DMB90, DMB140, DMB180, DMB210, DMB220, DMB230, DMB250, DMB300, DMB360, and DMB450.

Through bolts and side bolts are essential structural parts in a hydraulic breaker assembly. They help connect and secure the main breaker body, front head, cylinder, back head, bracket, and side plates. During rock breaking, concrete demolition, road construction, quarrying, mining, and trenching, the hydraulic breaker works under continuous impact force and strong vibration. The bolts must hold the breaker structure firmly and maintain stable assembly strength during operation.

If a through bolt or side bolt becomes loose, stretched, cracked, worn, or broken, the hydraulic breaker may experience abnormal vibration, weak impact, oil leakage, body misalignment, front head movement, cylinder damage, or serious structural failure. For repair workshops, spare parts distributors, construction contractors, quarry operators, mining customers, and equipment rental companies, replacing damaged bolts in time is important for safe and reliable hydraulic breaker operation.

This product is an aftermarket replacement through bolt and side bolt compatible with Daemo DMB Standard Series hydraulic breakers. The Daemo and DMB model names are used only for compatibility reference. YULINDINGLI supplies hydraulic breaker spare parts for repair, maintenance, rebuild, and aftermarket replacement needs.

Product Features

The Daemo DMB Standard Series through bolt and side bolt are designed for high-impact hydraulic breaker working conditions. These bolts must withstand repeated vibration, strong tensile force, shock load, and long working hours. Compared with ordinary bolts, hydraulic breaker bolts require better material strength, accurate thread machining, stable heat treatment, and reliable dimensional control.

Our through bolts and side bolts can be produced from selected alloy steel according to model requirements and customer needs. The production process usually includes material cutting, forging or forming, CNC machining, thread processing, heat treatment, grinding, and surface finishing. Proper heat treatment helps improve strength, toughness, and fatigue resistance, allowing the bolt to perform better under continuous impact vibration.

Thread accuracy is very important for hydraulic breaker bolts. Poor thread quality may cause difficult installation, uneven locking force, thread stripping, loosening, or early failure. A properly machined through bolt or side bolt can provide better fitting performance and help maintain the correct assembly force of the breaker body.

Dimensional accuracy is also essential. The bolt length, diameter, thread size, head shape, and fitting position must match the hydraulic breaker model. If the bolt is too short, too long, or incorrectly threaded, it may not lock the breaker parts properly. This may lead to structural looseness, abnormal noise, or damage to related components.

These bolts are suitable for regular breaker maintenance, urgent repair, hydraulic breaker rebuild projects, and spare parts stock. They can be supplied as single replacement parts or together with other hydraulic breaker components such as chisels, pistons, seal kits, inner bushes, outer bushes, front heads, back heads, cylinders, diaphragms, rod pins, and wear parts.

Main Advantages

The main function of the Daemo DMB Standard Series through bolt and side bolt is to secure the hydraulic breaker structure and keep the breaker assembly stable during operation. A reliable bolt set helps reduce abnormal vibration, maintain body alignment, and support stable impact performance.

For demolition applications, hydraulic breakers often work on reinforced concrete, building foundations, bridge structures, walls, and road surfaces. For quarry and mining work, the breaker may face hard rock, large stones, and continuous secondary breaking. In these demanding conditions, the bolts must resist repeated tensile stress and impact vibration. A poor-quality bolt may loosen or break quickly, causing machine downtime and higher repair costs.

Replacing damaged through bolts and side bolts in time can help protect other important hydraulic breaker parts. When the breaker body is not firmly secured, the cylinder, front head, back head, piston, seal kit, and chisel system may suffer abnormal stress. This can lead to oil leakage, unstable impact, faster wear, and expensive repairs. A properly matched bolt can help improve the service life of the whole breaker assembly.

For spare parts dealers and repair workshops, through bolts and side bolts are common replacement items. Keeping suitable bolts in stock can help repair hydraulic breakers faster and provide better service to end users. For contractors and rental companies, using correct bolts helps reduce job site failure and improves equipment safety.
