HYDRAULIC AND ELECTRIC SWIVEL JOINTS

SWIVEL JOINT

Gemels rotary distributors are designed for complex hydraulic applications where multiple fluid lines must be transferred simultaneously between fixed and rotating parts. They are ideal for excavators, cranes, aerial platforms, and drilling systems requiring operational continuity and reliability.

Available in configurations from 2 up to 20 passages, they enable efficient flow distribution in high-complexity hydraulic systems. Designed to operate up to 420 bar, they ensure high performance even under demanding conditions.

The structure allows controlled continuous rotation, preventing torsion and wear on piping. The optimized internal design ensures smooth flow management and long service life.

The option to integrate an electrical slip ring enables combined transmission of power and signals, making the rotary distributor a complete solution for advanced hydraulic and electromechanical systems.
