Epiroc EC Series Side Bolt For Breaker Housing Locking And Vibration Control

Product Introduction

The Epiroc EC Series Side Bolt For Breaker Housing Locking And Vibration Control is a replacement fastening part designed for excavator-mounted hydraulic breaker hammers. It is suitable for Epiroc EC Series hydraulic breakers, including common models such as EC40T, EC60T, EC70T, EC80T, EC90T, EC100T, EC120T, EC135T, EC140T, EC150T, EC155T, EC165T, and EC180T.

The side bolt is an important locking component used to secure the breaker housing, side plates, bracket area, and body structure. During hydraulic breaker operation, the hammer works under strong impact force, repeated vibration, and continuous shock load. The side bolt helps keep the breaker assembly tight, reduces abnormal movement, and supports stable working performance.

If the side bolt becomes loose, stretched, cracked, worn, bent, or thread-damaged, the hydraulic breaker may develop abnormal vibration, body noise, loose housing, side plate movement, uneven stress, impact power loss, or damage to nearby structural parts. In severe cases, continued operation with damaged side bolts may lead to housing deformation, broken mounting parts, or unsafe job site operation.

This product is an aftermarket replacement side bolt compatible with Epiroc EC Series hydraulic breakers. The Epiroc name and EC model references are used only for compatibility identification.

Material

Our Epiroc EC Series side bolts can be produced from selected alloy steel according to model size, working load, and customer requirements. Common material options may include 40Cr, 42CrMo, or other high-strength alloy steel depending on the application.

A side bolt must have high tensile strength, good toughness, fatigue resistance, and reliable thread performance. Hydraulic breakers work in harsh environments where vibration and impact are constant. If the material is not strong enough, the bolt may stretch, loosen, or break during operation.

Heat treatment is an important process for improving bolt strength and durability. Proper heat treatment helps the side bolt resist repeated impact vibration while maintaining stable toughness. The bolt surface can also be finished according to customer requirements to improve appearance, corrosion resistance, and installation performance.

Product Features

The main feature of the Epiroc EC Series side bolt is stable housing locking. Unlike smaller wear parts, the side bolt works as a structural fastening part. It helps maintain the correct position of the breaker housing, side plates, and related mounting components.

Accurate thread machining is very important. Poor thread quality may cause difficult installation, uneven locking force, thread damage, or early loosening. A correctly machined side bolt can provide better tightening performance and help maintain stable assembly force during high-impact breaker operation.

The bolt length, diameter, thread pitch, head shape, and fitting position must match the hydraulic breaker model. If the side bolt is too short, too long, or incorrectly threaded, it may not lock the breaker housing correctly. This can lead to vibration, abnormal noise, and faster wear on nearby parts.

The side bolt can be used for regular maintenance, breaker housing repair, side plate replacement, hydraulic hammer rebuild, and spare parts stock. It can also be supplied together with through bolts, rod pins, chisels, pistons, seal kits, bushings, diaphragms, front heads, back heads, cylinders, buffers, and wear plates.

Main Advantages

The main advantage of the Epiroc EC Series side bolt is that it helps improve structural stability during breaker operation. A reliable side bolt can reduce housing looseness, control vibration, and keep the hydraulic hammer body properly fastened.

For demolition contractors, hydraulic breakers often work on reinforced concrete, bridge structures, foundations, and road surfaces. For quarry and mining customers, the breaker may work continuously on hard rock and large stones. In these demanding applications, the side bolt must resist repeated vibration and shock load.

A damaged side bolt should be replaced in time. If the breaker continues working with loose or damaged bolts, the housing and side plates may suffer extra stress. This can also affect the front head, cylinder, back head, chisel system, and mounting bracket. Replacing the side bolt at the right time can help reduce repair cost and prevent more serious structural damage.

For repair workshops and spare parts distributors, side bolts are useful replacement items for hydraulic breaker maintenance. Keeping correct side bolts in stock can improve repair speed and help customers return equipment to work faster.
