| High Light | SB81 Inner Outer Bush ，Breaker Front Head Bush ，Hydraulic Hammer Guide Bush | ||
This complete inner and outer bush set is designed for Soosan SB81 and SB100 series hydraulic breakers. The bush (bushing) is a core wearable component installed inside the front head assembly, serving as the critical guide and support structure for the chisel reciprocating motion.

Precision Guidance: Maintains smooth and accurate chisel movement trajectory under frequent impact loading, eliminating chisel shaking and offset. Wear Protection: Acts as a sacrificial wear component, protecting the expensive front head cylinder body from direct abrasion. Impact Stability: Ensures consistent chisel alignment for maximum energy transfer to the breaking surface.
Each bush undergoes precision CNC machining followed by surface hardening and honing to achieve tight dimensional tolerances and a smooth inner bore finish. This reduces friction, extends chisel life, and minimizes maintenance frequency.
