Golden Ring Design Enerpac RD cylinders are provided with the Golden Ring Design, for long, trouble-free performance.

쑼 Clamping application using Enerpac RD cylinders (with clevis eye attachments on both ends) for their high-pressure capability and mounting flexibility.

• Designed for long life, the best choice for production applications • Unique mounting configurations simplify fixturing • Baked enamel finish for increased corrosion resistance • Double-acting operation develops force in both directions, providing maximum versatility • Plunger wiper reduces contamination, extending cylinder life
