Anti-Rust Wear-Resistance Hydraulic Breaker Pistons Hydraulic Hammer Pistons

(1) What are main materials of hydraulic breaker pistons?

Hydraulic breaker pistons mainly use high strength anti-wearing steels like GCr15,40CrNiMo with hardness

HRC 58-62.

(2) What are main features of hydraulic breaker pistons?

• High strength materials;
• Anti-resistance, anti-striking;
• Anti-rust technology;
• Long service life;
• Large quantity in stock;
• Complete models for selection

(5) Why hydraulic breaker pistons break?

1. Usually hydraulic breaker pistons bear large striking power which may cause breaker pistons breaking

because of fatigue after long-time using;

2. Lack of normal maintenance. Usually butter shall be filled every 2 hours to maintain lubricating and normal

working of pistons. If the piston is deformed, the cylinder liner and oil seal will also be worn. Then it may leak oil

and the impact will be weak. Excessive wear of the cylinder liner will directly cause the hammer to be scrapped.

3. Wrong operation. As hydraulic breaker fails to crush hard objects in 60 seconds, just strike it in another angle.

Striking once in a long time has to be avoided, or it will cause high temperature to speeden aging of the spare parts.
