High Wear Resistant Guide Bushing For Atlas Copco PB Series Mini Medium Excavator Hydraulic Rock Breaker

Atlas Copco PB series hydraulic breaker bushing is the core guide wear resistant component installed inside front head, serving small and medium excavator mounted PB hydraulic rock breakers. This wear spare part covers all mainstream models PB110 PB160 PB200 PB210 PB310 PB420 and PB530 matched with 3–12 ton excavators for urban construction landscaping and light quarry projects.

We supply various high strength alloy steel grades to adapt different working intensity including 40Cr 42CrMo 20CrMo GCr15 40CrNiMo 9Cr2MoV SCM440 SAE4140 SAE4340 with customizable material formula on request. Every guide bushing adopts one piece integral forging to eliminate internal metal defects and upgrade structural stability under frequent impact friction.

Special quenching and tempering heat treatment improves surface hardness and self lubricating performance. Smooth inner machined surface effectively cuts friction loss between bushing and chisel during continuous high frequency striking. All PB series bushings are processed by high precision CNC lathes to maintain ultra tight dimensional tolerance.

Perfect assembly with original front head housing keeps the breaking chisel running concentrically, avoiding eccentric abrasion abnormal impact noise and premature damage of piston seal kits and other internal parts. Applicable to small rock splitting concrete demolition foundation trimming asphalt cutting and municipal road renovation works.

Each finished bushing undergoes full dimension inspection friction endurance test and assembly matching check to meet OEM interchange standards. We keep abundant stock of all PB series specifications supporting small repair orders and large volume wholesale orders. Custom inner outer diameter machining service can be provided for global machinery maintenance factories and spare parts dealers.
