SB-Y1 Hydraulic Cylinder Heavy-Duty Industrial Solutions

Product Introduction

The SB-Y1 Hydraulic Cylinder is a national standard (GB/T 2348-1993 & JB/T 10205-2010) heavy-duty hydraulic cylinder widely used in metallurgical, mining, and engineering machinery.
It is part of China’s most mature standard hydraulic cylinder series and is designed to deliver high reliability, strong load capacity, and long service life in demanding industrial environments.

SB-Y1 cylinders are compatible with multiple mounting types, including flange, clevis, trunnion, foot, and center pin, allowing flexible integration into a variety of systems.

Key Features & Advantages

• Standardized & Interchangeable
  Dimensions, mounting types, and pressure ratings follow unified standards, simplifying procurement, maintenance, and replacement.

• Heavy-Duty Design
  Engineered for metallurgical, mining, and heavy machinery applications. High structural rigidity, high-pressure resistance, and shockproof.

• Proven Reliability
  Long-term market validation with mature manufacturing processes and low failure rates.

• High Rated Pressure
  Standard working pressure: 16 MPa (~160 kgf/cm²). Reinforced designs up to 25 MPa or higher.
