Atlas RDH Roundline Cylinders

Atlas Cylinders Series RDH industrial grade roundline welded hydraulic cylinders add value through proven reliability, efficient performance and the high quality you expect from every Atlas Cylinder Division product. Each Series RDH hydraulic cylinder includes superior design features for a 3,000 psi roundline welded cylinder. Features include: 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 combined with the Double-Service Wipersealâ„¢ 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 Atlas Cylinders ALS switches through carbon steel cylinders and EPS or CLS sensors are available for stroke position sensing. Port mounted counterbalance valves provide versatility by offering hose break protection, preventing loads from drifting and controlling overrunning loads.

All Atlas cylinder products have an eighteen month warranty and each Series RDH cylinder is individually tested before leaving our facility to ensure proper performance and leak-free operation.
