Reliable Fluid Transfer for High-Performance Automation
In modern factory automation, precision and efficiency are everything. Rotary unions—also known as rotary joints—play a vital role in enabling the seamless transfer of fluids (such as air, water, oil, or coolant) between stationary and rotating components.
At Penlink, we offer high-performance rotary unions for factory automation engineered to meet the demands of automated systems across a wide range of industries.
Our rotary unions are designed for use in:
- Rotary indexing tables: for pneumatic or hydraulic actuation
- Robotic arms: for air or coolant delivery to end-of-arm tools
- Packaging machines: for steam, vacuum, or compressed air
- Injection molding: for circulating cooling fluids
- Printing and converting equipment: for ink, air, or water transfer
