With a 14,700 lb load capacity and 3,500 PSI rating, it supports demanding hydraulic applications such as material handling, presses, and machinery requiring reliable extended reach. The tang configuration simplifies mounting, while robust steel construction ensures longevity in harsh operating environments.
Chief TC3 Tie-Rod Cylinder

The Chief TC3 tie-rod cylinder provides a 2″ bore, 6″ stroke, and a 16.25″ retract, rated at 3000 PSI with a 9,420 lb column load. SAE 8 port size supports easy integration with existing hydraulic systems. The tie-rod design offers a longer hydraulic base and improved swing, enhancing compatibility with agricultural, construction, and transport equipment. Performance testing and over-pressurization tolerance contribute to reliable operation in double-acting configurations.
2.5×30 Hydraulic Cylinder

This tang universal cylinder combines a 2.5″ bore with a long 30″ stroke, offering extended reach for lifting and pulling tasks. The welded construction and SAE 8 ports equip it for robust operations in industrial setups, with a rated 2500 PSI and 11,700 lbs load capacity. Its design emphasizes durability and versatility for production lines, vehicle repairs, and heavy equipment maintenance, especially where space allows longer strokes.
Buying Guide: Key Considerations And Comparisons
- Pressure rating: Verify maximum PSI to match your system’s operating pressure. Higher PSI supports heavier loads and faster cycles but may require sturdier mounting and seals.
- Bore and stroke: Choose bore size for force output and stroke length for movement range. Tang universal cylinders suit versatile mounting, while tie-rod designs offer modular adaptability.
- Port type and size: SAE ports are common; confirm compatibility with your hoses and fittings. Ensure seals and O-rings have matching AS568 specifications for reliability.
- Seal material: Fluorocarbon (FKM/Viton) resists heat, oil, and many chemicals, ideal for hydraulic and aerospace applications. Consider operating temperature and exposure when selecting O-ring kits.
- Construction quality: Welded versus tie-rod constructions impact rigidity, alignment, and durability in outdoor or rugged environments. All-welded designs typically offer higher strength in demanding tasks.
- Maintenance features: Look for tight seals and accessible ports. Kitted O-rings with maintenance tools reduce downtime during repairs and replacements.
- Compatibility: Ensure selected cylinders and O-ring kits suit your cylinders, bearings, valves, and plumbing fixtures. A matched kit reduces part variety and simplifies inventory.
- Application scope: For aerospace or automotive contexts, choose materials and standards aligned with AS568 and industry-specific requirements to ensure long-term performance.
These options provide a spectrum of configurations—from compact, high-speed applications to long-stroke, high-load tasks. When evaluating, consider the operating environment, required force, cycle frequency, and ease of installation. The combination of robust cylinders and fluorocarbon O-rings helps ensure reliable sealing under high pressure, extreme temperatures, and challenging fluids across industrial, automotive, and servicing scenarios.
