Product Introduction

The Trunnion Mount at Base SB-Y1 Hydraulic Cylinder is designed for heavy-duty pivoting applications, with a trunnion located at the cylinder base. This mounting configuration is one of the most reliable solutions for high-load, high-inertia systems, ensuring stable operation under demanding conditions.

By allowing controlled pivoting at the base, this cylinder is ideal for metallurgical main equipment, mining hydraulic systems, and heavy engineering machinery, where strong impact resistance and precise load transmission are critical.

Why This Cylinder Was Designed

In heavy-duty pivoting applications, conventional fixed mounting can cause excessive stress and reduce cylinder service life.
The Base Trunnion Mount configuration addresses these challenges by:

• Providing strong impact and shock resistance

• Supporting high-load, high-inertia systems

• Delivering proven industrial reliability for long-term operation

It is the preferred choice for manufacturers who need robust, durable hydraulic cylinders for extreme pivoting workloads.

Structural & Performance Advantages

✔ Strong Impact Resistance

Base trunnion mount absorbs shock loads effectively, protecting both the cylinder and connected machinery.

✔ Designed for High Loads & High Inertia

Optimized for heavy-duty systems with significant mass and dynamic forces.

✔ Mature and Reliable Engineering

Proven design and precision manufacturing ensure long-term reliability under severe industrial conditions.

✔ Industrial-Grade Stability

Coaxial machining of trunnion and cylinder base minimizes eccentric loading and wear, improving lifespan.
