Precision Honed Inner and Outer Bush Set for Soosan SB81 Hydraulic Breaker

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.

Technical Specifications

Three Critical Functions

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.

Manufacturing Quality

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.
