Product Introduction

The Trunnion Mount at Head SB-Y1 Hydraulic Cylinder is designed for applications where the piston rod end connects to swing arms or linkages, allowing controlled pivoting at the front end.

By mounting the trunnion at the rod-end, this cylinder accommodates complex motion paths while reducing stress on the connecting components. It is ideal for articulated machinery and linkage-driven systems, ensuring smooth operation under variable load conditions.

Why This Cylinder Was Designed

In mechanical systems with articulated or oscillating motion, rigid rod-end mounting can create high stress at connection points and reduce service life.
The Trunnion Mount at Head configuration addresses these challenges by:

• Allowing controlled front-end pivoting for swing or linkage mechanisms

• Reducing stress on piston rod and connected linkages

• Supporting long-term stability and reliability under dynamic loads

This design is optimal for manufacturers requiring flexible rod-end motion with heavy-load capability.

Structural & Performance Advantages

✔ Front-End Pivot Capability

The trunnion at the piston rod end allows rotational freedom, adapting to complex motion trajectories.

✔ Reduces Connection Stress

Pivoting design minimizes bending and shear forces on the piston rod and connected linkages.

✔ Supports Heavy Loads and Long Strokes

Optimized trunnion dimensions and bearing selection ensure stability under maximum load.

✔ Industrial Reliability

Precision-machined trunnion interfaces reduce eccentric loading and wear, ensuring extended service life.
