Schrader Bellows Series RDH
Series RDH industrial grade heavy duty roundline hydraulic cylinders are field repairable and provide extremely long cycle life. Series RDH is 3,000 psi rated and configurable in 9 standard mounts, strokes to suit your needs and many standard options.
Schrader Bellows Series RDH industrial grade roundline welded hydraulic cylinders provide value through proven reliability, efficient performance and the quality that you expect from every Schrader Bellows Cylinder Division product line. Each Series RDH hydraulic cylinder has design features that are superior in a 3,000 psi roundline welded cylinder. Included features are: energized bi-directional piston seal, standard composite wear rings both in the head and on the piston, and hard chrome plated piston rods.
The Tri-Lip Rod Seal in combination with the Double-Service Wiperseal™ comprises a sealing system that delivers dry rod performance. The one-piece piston is piloted to the piston rod and sealed with an O-ring to eliminate oil bypass through the joint. Anti-extrusion design o-ring Body End Seals provide leak-free service. Magnetic piston for actuating Schrader Bellows ALS switches through carbon steel cylinders and EPS or CLS sensors are available for stroke position sensing. Port mounted counterbalance valves add versatility by offering hose break protection, preventing loads from drifting and controlling overrunning loads.
All Schrader Bellow cylinder products carry an eighteen month warranty and each Series RDH cylinder is individually tested before leaving our plant to assure proper performance and leak-free operation.
