SB81 HB20G Hydraulic Breaker Parts Piston, Hydraulic Hammer Piston
Product Overview
The SB81 HB20G hydraulic breaker piston is a core wearable component for excavator hydraulic hammer equipment. As a key hydraulic hammer piston part, it undertakes the main impact and pressure transmission work of the hydraulic breaker. Manufactured with high-purity alloy steel and professional precision heat treatment technology, this breaker piston features ultra-high hardness, strong pressure resistance and excellent fatigue resistance. It effectively solves common problems such as piston jamming, insufficient striking force and oil cylinder wear, ensuring stable, high-efficiency and long-lasting operation of the hydraulic breaker in various heavy-duty construction scenarios.
Product Advantages
This SB81 HB20G hydraulic hammer piston adopts one-piece forging molding process without secondary splicing, which completely avoids the risk of fracture and deformation under high-frequency impact. The internal and external surfaces are precisely polished with smooth texture, which reduces friction with the cylinder body, prevents oil leakage and jamming, and greatly improves the working efficiency of the hydraulic breaker.
Stronger pressure bearing capacity compared to ordinary pistons
Lower failure rate for reduced maintenance costs
Longer service life minimizing downtime losses
Strict quality inspection for dimensional accuracy and surface finish
Every hydraulic breaker piston is strictly inspected for dimensional accuracy, surface finish and pressure resistance before delivery. We support bulk wholesale and customized processing, providing high-quality and cost-effective hydraulic breaker spare parts for global engineering machinery dealers and construction contractors.
