MTB GA Series Hydraulic Breaker Through Bolt Tie Rod Bolt Spare Parts

MTB GA Series Hydraulic Breaker Through Bolt  Tie Rod Bolt Spare Parts

Our MTB GA Series Hydraulic Breaker Through Bolt, also known as tie rod bolt, is the critical load-bearing structural spare part for MTB GA gas-type closed box hydraulic breakers. The through bolt runs through the entire breaker body to tightly clamp the front head, cylinder and back head together into one rigid assembly. It bears huge cyclic tensile force and vibration loads during continuous rock impact, maintains component alignment and compresses joint face seals to prevent oil leakage.

Each MTB GA breaker through bolt is forged from high-grade 42CrMo alloy steel, with precision thread rolling and multi-step quenching & tempering heat treatment. The finished bolt delivers ultra-high tensile strength and excellent fatigue resistance, effectively resisting stretching, loosening and fatigue cracking under heavy mining and demolition working conditions. Precision thread control ensures perfect matching with nuts, stable pre-torque and reliable locking performance.

We supply full model coverage for MTB GA series breakers: GA70, GA100, GA150, GA200, GA300, GA400. Our replacement through bolts are direct interchangeable parts for original MTB GA hammer, widely fitted on excavator-mounted hydraulic hammers for open-pit mining, rock quarrying, concrete demolition, road construction and boulder breaking. Cracked, stretched or fatigued through bolts will cause separation of hammer components, oil leakage and total breaker failure, so timely inspection and replacement are essential.

OEM & custom machining service is available. We can produce through bolts according to your technical drawings or physical sample requirements. All MTB GA breaker through bolts are supplied at competitive factory price, controllable lead time and reliable after-sales support.

FAQ Section

A: Our replacement tie rod through bolts fit full MTB GA gas closed-box breaker range: GA70, GA100, GA150, GA200, GA300, GA400. Please provide your exact GA model number, we will verify the bolt length and thread specification.

Q2: What material are MTB GA breaker through bolts made of?

A: Made of 42CrMo high strength alloy steel. Forged and heat-treated to achieve high tensile strength and anti-fatigue performance to withstand repeated cyclic impact tension.

Q3: What is the function of breaker through bolt?

A: Through bolts tie front head, cylinder and back head tightly together. It absorbs cyclic tension and vibration during hammer operation, keeps all components aligned, and maintains sealing pressure to avoid hydraulic oil leakage. Damaged through bolt may lead to catastrophic hammer breakdown.

Q4: What are the signs that my through bolt needs replacement?

A: Bolt elongation, visible fatigue cracks, thread damage, frequent loosening under operation, oil leakage at joint faces or abnormal vibration noise. Stop operation and replace immediately to prevent major damage.

Q5: Can you make custom size MTB GA through bolts?

A: Yes, OEM custom service is supported. Send us your old bolt sample, dimension parameters or technical drawing, we can manufacture as requested.

Q6: What is MOQ and production lead time?

A: Small trial orders are acceptable for standard sizes. Lead time normally 7–15 working days, subject to quantity and stock availability. Contact us for latest stock status.

Q7: What working scenarios suit MTB GA breaker through bolts?

A: Ideal for open-pit mine, rock quarry, concrete demolition, road construction and boulder breaking. Perfect match for MTB GA closed silent box gas hammers.

Q8: What payment terms do you accept?

A: T/T, L/C are available. Payment terms can be negotiated according to your order volume.
