Heavy Duty Hydraulic Cylinder

Parker Series RDH Heavy Duty Hydraulic Cylinder – Industrial-Grade Performance and Reliability

The Parker Series RDH heavy duty roundline welded hydraulic cylinder is engineered to deliver the quality and performance expected from Parker’s Cylinder Division. Designed for a wide range of industrial applications, this 3,000 PSI cylinder incorporates advanced sealing technology and robust construction for long-lasting, trouble-free operation.

Superior Sealing System for Dry Rod Performance

The Series RDH features a Tri-Lip Rod Seal in combination with the Double-Service Wiperseal, creating a sealing system that delivers dry rod performance and positive no-leak sealing . This advanced design helps prevent oil bypass through the piston joint by piloting the one-piece piston to the piston rod and sealing with an O-ring. Anti-extrusion design O-ring body end seals further ensure leak-free service.

Durable Construction for Demanding Environments

Each RDH cylinder incorporates design features superior in a roundline welded cylinder, including standard composite wear rings in both the head and the piston, and hard chrome-plated piston rods for extended wear life . The heavy-duty construction ensures reliable performance in industries such as energy production, mining, oil and gas, factory automation, and lumber processing .

Advanced Control and Position Sensing Options

For applications requiring position feedback, an optional magnetic piston allows for actuating Parker ALS switches and EPS or CLS sensors . Port-mounted counterbalance valves add versatility by offering hose break protection, preventing loads from drifting, and controlling overrunning loads, making this cylinder suitable for lifting and positioning applications.

Quality Assured

Every Series RDH cylinder is individually tested before leaving the plant to ensure proper performance and leak-free operation, backed by an eighteen-month warranty .
