Parker Hannifin's Industrial Cylinder Division released the Series RDH Roundline Cylinder line. The RDH Series is a heavy-duty, industrial-grade repairable welded cylinder. It features robust design, advanced sealing technology and exterior toughness to satisfy demands of industrial applications.

Its cost-effectiveness and short lead times (catalog-standard product) make it a great choice for our industrial customers.

## Quick Facts:

- Threaded head, welded cap (repairable)
- 3,000 psi hydraulic service
- 1-1/2" to 8" bore diameters
- 5/8" to 5-1/2" rod diameters
- Standard strokes to 120"
- 9 standard mounts (most are NFPA)
- Standard temperature -10°F to +165°F
- All popular seal compounds
- Parker WearGardTM bearings for rod and piston
- Many model code options and common modifications
- Manufactured in the U.S.A.
