Product Description
- Solid round bar hot forging forming, dense internal metal grain, eliminate inner shrinkage cavity to avoid tensile elongation under long-term vibration.
- Multi-section necking buffer design consistent with OEM structure, disperse concentrated impact stress, greatly reduce bolt sudden breakage rate.
- Full CNC precision thread rolling, complete uniform thread tooth, tight matching with original lock nut, anti-loosening under heavy vibration.
- Integral quenching + high-low temperature tempering treatment, balance surface tensile strength and core toughness, anti-fatigue & anti-stretch.
- Black oxide anti-rust surface finish, resistant to mine muddy, damp open-air construction corrosive environment.
- Standard chamfer at two thread ends, convenient diagonal cross tightening during field maintenance installation.
- Independent plastic wrap + export carton packing, avoid thread collision damage during long-distance sea transportation.
- Four sets of side through bolts symmetrically pass through front head, middle cylinder, back head along breaker lateral direction.
- Cross diagonal torque tightening locks three separated hammer components into integrated whole cylinder assembly.
- When piston high-frequency strikes chisel, vibration & impact force transfers to cylinder wall, bolts bear alternating tensile stress constantly.
- Middle neck buffer structure disperse concentrated stress, avoid stress concentration crack on bolt rod body.
- Lock nut + flat washer auxiliary anti-loose, keep pre-tightening force stable in long-time continuous construction.
- 7*24h online professional technical support: model confirmation, installation torque guidance, bolt failure cause analysis for global buyers.
- Three-level pre-shipment QC: raw material test→full dimension inspection→random mechanical performance spot check.
- OEM customization available: print customer private brand logo on export carton, customized packaging specification.
- Multiple logistics options: sea freight, air freight, international express with full cargo tracking information.
- One-stop full SB121 spare supply: piston, chisel, flat pin, seal repair kit, diaphragm all in ready stock.
