Soosan SB50 Hydraulic Breaker Piston

This aftermarket Soosan SB50 hydraulic breaker piston replacement is specifically designed for SB50 model breakers, featuring a standard diameter of 100mm and perfectly matching 11-16 ton class excavators. It is the ideal aftermarket replacement part for repair shops and distributors, widely used in heavy-duty applications such as mining, construction demolition, and rock breaking.

Manufactured through an integral high-strength alloy steel forging process and advanced vacuum quenching and tempering heat treatment, this piston achieves a standard surface hardness of HRC 56–60. This precision process ensures a perfect balance of extreme surface wear resistance and excellent internal toughness, effectively reducing cylinder scoring risks and fatigue cracks under continuous high-frequency strikes, while maintaining oil film stability to prolong the breaker's lifespan.
