Everdigm EHB Series Through Bolt / Side Bolt For Body Clamping And Shock Stability

Product Introduction

The Everdigm EHB Series Through Bolt Side Bolt For Body Clamping And Shock Stability is designed for excavator-mounted hydraulic breaker hammers. It is suitable for Everdigm EHB Series hydraulic breakers, including common models such as EHB02, EHB04, EHB05, EHB13, EHB17, EHB20, EHB25, EHB30, EHB40, and EHB50.

Through bolts and side bolts are important fastening parts in the hydraulic breaker structure. The through bolt is mainly used to clamp and connect the main breaker body sections, helping keep the front head, cylinder, back head, and internal structure aligned under impact load. The side bolt is commonly used for side plate fastening, housing locking, bracket area support, and frame stability.

During hydraulic breaker operation, the hammer works under repeated impact force, vibration, hydraulic pressure, and shock load. If the through bolt or side bolt becomes loose, stretched, cracked, worn, bent, or broken, the breaker may develop abnormal noise, body looseness, side plate movement, oil leakage, weak impact, structural misalignment, and higher repair cost.

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

Material

Our Everdigm EHB Series through bolts and side bolts are commonly produced from selected high-strength alloy steel according to model size, working load, and customer requirements. Common material options may include 40Cr, 42CrMo, or other high-tensile alloy steel.

Bolts used in hydraulic breakers must have strong tensile strength, good toughness, impact resistance, fatigue resistance, and stable thread performance. The breaker works continuously with high-frequency vibration, so poor material may cause the bolt to stretch, loosen, or break during operation.

Heat treatment is an important process for improving bolt strength and durability. Proper heat treatment helps the bolt resist repeated shock load while maintaining enough toughness. Accurate thread machining also helps improve tightening performance and installation stability.

Surface treatment can be supplied according to customer requirements, including black finish, anti-rust oil, phosphating, coating, or other custom treatment.

Product Features

The main feature of the Everdigm EHB Series through bolt and side bolt is structural fastening. These bolts are not ordinary hardware items. They are critical breaker body parts that help maintain hammer alignment and working stability.

The through bolt helps hold the main breaker body together. It supports the connection between different hammer sections and helps resist the separating force caused by repeated impact. If the through bolt is not properly tightened or is already damaged, the hammer body may become loose and internal parts may wear faster.

The side bolt mainly supports side frame locking and side plate stability. It helps keep the breaker housing tight during demolition, concrete breaking, trenching, road repair, quarry work, and other heavy-duty applications.

Correct size is very important. Bolt length, diameter, thread pitch, head design, and fitting position must match the breaker model. If the bolt is too long, too short, or incorrectly threaded, it may not provide proper locking force. This can lead to vibration, loose housing, uneven stress, and repeated repair problems.

Main Advantages

The main advantage of the Everdigm EHB Series through bolt and side bolt is improved body stability. A correctly matched bolt set helps keep the hydraulic breaker structure tight, reduces abnormal vibration, and supports safer hammer operation.

For demolition contractors, stable fastening helps the breaker handle reinforced concrete, building foundations, walls, pavement, and road surfaces. For municipal construction and road repair teams, reliable bolts help maintain hammer stability during asphalt removal, curb breaking, and trenching work. For quarry and stone breaking applications, the bolts must resist continuous impact vibration and long working hours.

Timely bolt replacement can also protect other hydraulic breaker parts. If damaged bolts continue working, the front head, cylinder, back head, side plate, bracket, piston, seal kit, and bushing system may suffer extra stress. Replacing loose or cracked bolts in time can help reduce larger structural damage and lower total maintenance cost.

For repair workshops and spare parts dealers, through bolts and side bolts are important maintenance parts. Keeping correct Everdigm EHB Series bolt sets in stock can help customers complete breaker repairs faster and reduce equipment downtime.

FAQ

Q1: Are these bolts original Everdigm parts?
No. These are aftermarket replacement through bolts and side bolts compatible with Everdigm EHB Series hydraulic breakers. The Everdigm name and model references are used only for compatibility identification.

Q2: What is the function of a hydraulic breaker through bolt?
The through bolt helps clamp and connect the main breaker body sections, supporting the front head, cylinder, back head, and internal structure under impact load.

Q3: What is the function of a side bolt?
The side bolt helps lock the breaker side frame, housing, side plates, and bracket area. It supports structural stability and reduces abnormal vibration.

Q4: When should I replace through bolts or side bolts?
They should be replaced when they are loose, stretched, cracked, bent, worn, broken, or thread-damaged. Abnormal housing noise or body looseness also means the bolts should be inspected.

Q5: What problems can damaged bolts cause?
Damaged bolts may cause body looseness, side plate movement, abnormal vibration, oil leakage, weak impact, structural misalignment, and damage to nearby breaker parts.

Q6: How can I confirm the correct bolt size?
You can provide the breaker model, old bolt length, diameter, thread size, head shape, photos, drawings, samples, or part numbers. We can help confirm the correct item before shipment.

Q7: Can I order bolts with other hydraulic breaker parts?
Yes. Through bolts and side bolts can be supplied together with chisels, rod pins, pistons, seal kits, bushings, diaphragms, front heads, back heads, cylinders, buffers, and wear plates.
