Atlas Copco SB Series Hydraulic Breaker Through Bolt High Tensile Forged Alloy Steel Demolition Hammer Tie Rod Fastener Spare Parts

Atlas Copco SB series hydraulic breaker through bolt also named tie rod is the core tension fastener that tightly combines front head main cylinder and rear accumulator housing into one integrated solid unit. This critical fastening spare part fits all mainstream SB solid body breaker models SB50 SB52 SB100 SB102 SB150 SB152 SB200 SB202 SB300 SB302 SB400 SB450 SB452 SB552 SB702 and SB850 matched with 1–16 ton excavators for demolition and light rock breaking work.

We supply multiple high strength alloy steel grades with 42CrMo as the standard preferred material for heavy demolition loads. Alternative steel materials include 40Cr 20CrMo GCr15 40CrNiMo 9Cr2MoV SCM440 SAE4140 SAE4340 with customizable material hardness formula on demand.

Each through bolt adopts one piece integral forging craft to eliminate internal metal segregation shrinkage cavities and hidden micro cracks. Complete quenching and tempering heat treatment significantly improves tensile yield strength and long cycle fatigue resistance. It can maintain stable clamping tension under long hours of high frequency impact to avoid bolt elongation breakage or loose assembly gaps.

All thread sections adopt precision rolling machining to guarantee accurate thread pitch and matching tolerance. Evenly installed multiple through bolts fix all breaker housings tightly together, effectively reducing running vibration blocking hydraulic oil leakage and stabilizing consistent breaking efficiency on busy construction sites.

Applicable working scenarios include building interior dismantling concrete slab breaking wall demolition asphalt cutting foundation trimming landscaping and small quarry secondary crushing projects. Each batch of through bolts undergoes tensile strength test thread precision inspection and impact fatigue cycle test to reach OEM interchange standards.

We hold full stock of all SB series through bolt specifications supporting small repair retail orders and large volume wholesale orders for demolition contractors and machinery rental firms. Custom length diameter and thread standard production service can be provided for global machinery maintenance factories and spare parts dealers.
