Hydraulic Cylinder, Heavy Duty Industrial – Gen II Series 2H, 3H Family (Americas)

Parker Gen II Series 2H/3H Heavy Duty Hydraulic Cylinders – Industrial-Grade Performance and Reliability

The Parker Gen II Series 2H and 3H heavy duty hydraulic cylinders are engineered to meet the rigorous demands of industrial applications across multiple sectors. These cylinders are available in tie-rod style (Series 2H/2HD and 3H/3HD) and non-tie rod (Series 2HB/3HB) configurations, delivering superior performance and durability that ensure long service life and reduced operating costs.

Key Performance Specifications

Built to a robust 3000 PSI working pressure, these cylinders comply with ANSI/(NFPA) T3.6.7R3-2009 standards, ensuring they meet stringent industry requirements. They are designed for use with hydraulic oil and operate effectively across a wide temperature range of -10°F to +165°F.

Comprehensive Size and Mounting Options

The Series 2H family offers bore diameters from 1.5 inches through 6 inches, while the Series 3H family covers larger bore sizes from 7 inches through 20 inches. Rod diameters range from 0.625 inches to 5.5 inches. With 19 standard mounting styles available, these cylinders can be configured to suit virtually any application requirement, with any practical stroke length available.

Superior Design Features for Enhanced Productivity

Several key design features contribute to the exceptional performance of the Series 2H/3H cylinders:

• “Jewel” Rod Gland Assembly: This precision-engineered component increases machine productivity and ensures reliable operation.

• Advanced Sealing Systems: The TS2000 Rod Seal (in Series 2H/3H) and Tri-Lip Rod Seal (in Series 2HD/3HD/2HB/3HB), combined with the standard polyurethane Double-Service Wiperseal™, deliver dry rod performance and positive no-leak sealing.

• Universal Piston Design: The innovative Universal Piston features four seal options, allowing for easy in-field seal style changes and balancing low pressure sealability, low friction, extrusion resistance, and seal life.

• Hard Chrome Plated Piston Rods and Stepped Cushions: These features work together to maximize machine uptime and productivity.

Quality Assurance and Warranty

Every Series 2H/3H, 2HD/3HD, and 2HB/3HB cylinder is individually tested before leaving the Parker plant to ensure proper performance and leak-free operation, backed by an eighteen-month warranty.

Diverse Market Applications

These cylinders serve a wide range of industrial markets, including:

• Industrial and factory automation

• Energy production, development, and power generation

• Mining, oil and gas

• Food and beverage processing

• Machine tools, molding, and plastic processing

• Vehicle assembly facilities

• Lumber and wood processing

Feedback/Electrohydraulic Options

For applications requiring precise position and velocity control, feedback cylinders are available through the Parker Series 2HX/3HX. These electrohydraulic cylinders integrate position sensing devices and valve manifolds directly into the cylinder assembly, eliminating the need for separate components.

Legacy Model Conversion Support

Parker provides a legacy-to-next-gen model code conversion tool to help customers transition existing Parker 2H/2HD/3H/3HD hydraulic tie rod cylinder model numbers to the Gen II equivalent, ensuring seamless replacement and compatibility.

The Parker Advantage – Engineered for Long Service Life

Parker’s superior design, use of high-quality materials, and stringent manufacturing practices make the Series 2H/3H cylinders the industry standard for heavy-duty hydraulic actuation.
