Double Acting Hydraulic Cylinder With Industrial Ball Joints (70/40)

This double acting hydraulic cylinder with ball joints (70/40) is engineered for demanding agricultural, construction, and industrial applications. The integrated ball joints (also known as spherical bearings or heim joints) allow for angular movement and compensate for misalignment, reducing stress on the cylinder and mounting points.

This design makes the cylinder ideal for dynamic applications where rigid mounting would cause excessive wear. The flexible joint construction improves performance, extends service life, and ensures smoother operation under load.

The cylinder is fully assembled and ready for immediate installation. It features a precision-engineered piston with a special locking ring, ensuring secure operation and reliable performance in heavy-duty conditions.

Important Notes

• All cylinders are painted black for corrosion protection during storage and transport
• Minor scratches may occur and are not considered defects
• Protect the cylinder from welding spatter during installation

Applications

Suitable for tractors, agricultural implements, construction equipment, and industrial hydraulic systems requiring flexible mounting and reliable push-pull force.

Why Choose Ball Joint Cylinders?

• Better alignment tolerance than clevis or rigid mount cylinders
• Ideal for dynamic applications with movement
• Reduced wear and longer service life
