Atlas Copco FKM Hydraulic Breaker Seal Kits Anti Leak Overhaul Spare Parts

Atlas Copco SBU Series Hydraulic Breaker Seal Kits Heavy Mining Anti-Leak Overhaul Spare Parts

SBU series seal kits are full overhaul maintenance sealing packages exclusively designed for heavy-duty Atlas Copco SBU large hydraulic breakers, covering all models ranging from SBU220 to SBU2000. The complete set covers all sealing positions of piston cylinder front guide and nitrogen accumulator, widely applied in open pit hard rock mining tunnel excavation and large industrial building demolition projects.

We adopt multi-grade composite sealing materials to adapt harsh mining working environments. FKM Viton delivers outstanding high temperature and hydraulic oil resistance for continuous heavy-load operation, high toughness PU buffer seals resist impact extrusion, and PTFE back up rings effectively prevent seal rupture under ultra-high hydraulic pressure.

All sealing parts are precision compression molded with strict dimensional tolerance for direct OEM replacement without trimming. Complete matching eliminates oil leakage and pressure loss, stabilizes breaker striking power and cuts maintenance frequency of core metal spare parts like piston and bushing.

Each batch of seal kits passes hydraulic tightness test high temperature oil aging test and reciprocating friction endurance inspection to reach original equipment interchange standard. Full model stock supports small retail repair orders and large bulk wholesale for mining groups and demolition contractors. Custom combined seal combinations and branded packaging service are available for global machinery maintenance factories and dealers.
