Meta Description: Expert Guide to High-Performance Silver HB15G, HB20G, HB30G, HB40G Hydraulic Breaker Cylinders – For All Kinds of Hydraulic Hammers, Stone & Road Breakers

In the fields of construction, demolition, and quarrying, the hydraulic breaker’s cylinder is the vital core that determines its impact power, durability, and overall performance. Guchuan’s Series cylinders—specifically engineered for HB15G, HB20G, HB30G, and HB40G models—represent the pinnacle of precision manufacturing for all kinds of hydraulic breaker hammers, stone crushers, and road breakers.

Our cylinders are designed for use in a wide range of hydraulic breaker hammers, ensuring compatibility with various brands and models. Each cylinder is the result of advanced manufacturing processes and strict quality standards.

• Precision Machining:
  Every Silver Series cylinder undergoes ultra-precise boring and honing (Ra ≤ 0.2μm) to create a mirror-smooth inner wall. This reduces piston friction, enhances seal life, and maintains optimal hydraulic efficiency.

• Premium Materials:
  Forged from high-grade alloy steel (42CrMo, 40CrNiMo, etc.), each cylinder is tested for internal flaws before production to ensure safety and reliability.

• Special Heat Treatment:
  Multi-stage quenching and tempering achieve a perfect balance of surface hardness (HRC 50-55) and core toughness, guaranteeing resistance to wear, fatigue, and shock loads.

• Universal Compatibility:
  Designed for HB15G, HB20G, HB30G, HB40G, and suitable for a wide range of hydraulic breaker hammers and stone/road breakers on the market.

• Optimal Seal Performance:
  Perfect groove dimensions and finely honed surfaces provide an ideal fit for high-quality seals, reducing oil leakage and maintaining stable nitrogen pressure.

• Enhanced Durability:
  Superior material selection and treatment provide excellent resistance to scoring, deformation, and cyclical stress—even under extreme working conditions.

• Efficient Oil Channel Design:
  Precision-machined oil passages ensure smooth and rapid hydraulic flow, maximizing impact power and reducing energy loss.

• Long Service Life:
  Guchuan cylinders are engineered for extended use, reducing downtime and total cost of ownership for your hydraulic hammer fleet.

• Suitable for all major brands of hydraulic breaker hammers and attachments, especially compatible with HB15G, HB20G, HB30G, and HB40G models.
• Widely used in:
  • Stone quarrying and mining
  • Road construction and foundation breaking
  • Demolition of reinforced concrete and urban infrastructure
  • Trench excavation and pipeline projects

• OEM Quality Guarantee:
  100% original manufacturer standard, ensuring perfect fit and trouble-free installation.
• R&D Driven:
  Continuous innovation and technical upgrades based on customer feedback and field experience.
• Comprehensive Support:
  Fast delivery, technical guidance, and after-sales service to support global customers.
