Hydraulic Atlas Copco Concrete Breaker Parts Bushing Guide Wear For Rock Demolition Hammer

Atlas Copco SB Series Hydraulic Breaker Bushing 42CrMo Forged Alloy Anti Friction Guide Wear Spare Parts For Demolition Hammer

Atlas Copco SB series hydraulic breaker bushing also named front guide bushing is the critical friction-resistant wear component installed inside the front housing of SB solid body hydraulic breakers. This replacement spare part fits all mainstream models SB50 SB52 SB100 SB102 SB150 SB152 SB200 SB202 SB300 SB302 SB400 SB450 SB452 SB552 SB702 and SB850, widely matched with 1–16 ton excavators for urban demolition and light rock breaking jobs.

We produce SB series guide bushings with multiple high-strength alloy steel grades, with 42CrMo as the mainstream standard material for heavy demolition workloads. Optional materials include 40Cr 20CrMo GCr15 40CrNiMo 9Cr2MoV SCM440 SAE4140 SAE4340 with customizable material formula based on customer site conditions.

Each bushing adopts one-piece integral forging craft to eliminate internal metal segregation and micro cracks. Special quenching and tempering heat treatment improves surface hardness and self-lubricating performance. Precision CNC internal and external turning creates ultra-smooth inner bore surface to minimize friction loss between bushing and chisel shank during continuous high-frequency striking.

Ultra-tight dimensional tolerance ensures perfect assembly matching with original SB front head housing. The guide bushing keeps the breaking chisel running on a central axis, effectively avoiding eccentric abrasion, abnormal impact noise, oil seal damage and premature failure of piston and other core internal spare parts on busy demolition construction sites.

Applicable scenarios cover indoor building dismantling concrete slab breaking wall demolition asphalt pavement cutting foundation trimming landscaping and small quarry secondary crushing works. Every finished bushing undergoes full dimension inspection, friction endurance test and assembly fitting verification to meet OEM interchange standards.

We maintain complete stock of all SB series bushing specifications to support small repair retail orders and large volume wholesale for demolition contractors and machinery rental firms. Custom inner diameter outer diameter and length processing service can be offered for global machinery maintenance factories and spare parts dealers.
