Double Acting Universal Hydraulic Cylinder, 16″ Stroke
The Wryxia Double Acting Universal Hydraulic Cylinder provides versatile use across industrial equipment and machinery. Its chrome-plated piston rod enhances durability and rust resistance, supporting longer service life in demanding environments. With a working pressure of 2900 PSI and a maximum allowable pressure of 3600 PSI, this cylinder is suited for high-load applications where controlled extension and retraction are required. The automatic welding construction contributes to robust integrity in field installations and workshop setups. This model is designed to work effectively in systems that demand reliable, double-acting hydraulic action.
Key considerations include mounting compatibility, stroke length at 16 inches, and pin hole size of 1.0 inch. Users should verify the cylinder’s bore size and port configuration to ensure seamless integration with existing hydraulic hoses and control valves. Maintenance should emphasize keeping the chrome surface clean to preserve corrosion resistance and reduce wear on seals and guides over time.
DOZYANT Gas Lift Cylinder Replacement
While designed primarily for office chairs, the DOZYANT gas lift cylinder represents a robust gas-ram alternative for lightweight, vertical adjustment systems. It supports up to 450 lbs on most executive chairs and features a standard diameter layout: outer cylinder 2 inches and inner cylinder 1.1 inches. The cylinder ensures smooth, quiet movement with full 360-degree rotation, making it suitable for ergonomic furniture where fluid lift and steady hold are essential. For hydraulic-focused systems, ensure compatibility with gas-charged configurations if your application requires pneumatic action rather than purely hydraulic.
Double Acting Universal Hydraulic Cylinder with Hydraulic Lock
The second Wryxia model adds a hydraulic lock feature to the standard double-acting design, using a chrome-plated piston rod and a robust construction that can tolerate 2900 PSI working pressure and up to 3600 PSI maximum. This variant’s stroke is 12 inches, with a 1.0 inch pin hole, making it a flexible choice for equipment that requires a compact, lockable extension. When integrating this unit, verify the hydraulic lock mechanism’s actuation method, as well as port sizing and mounting alignment to ensure reliable locking under load and accurate retraction.
Kingway Hydraulic Double Acting Cylinder (12″ Stroke)
The Kingway hydraulic cylinder combines heavy-duty construction with practical versatility. It delivers 3500 PSI, with a 12-inch stroke and a 0.75-inch pin hole design, compatible with SAE#6 ports. The cylinder uses high-quality steel with hard chrome plating to resist corrosion in tough environments, making it suitable for construction, agricultural, and industrial applications. Its mounting and port arrangements are designed to integrate with front-end loaders and machinery that require reliable, high-load piston action. Ensure port compatibility and external mounting geometry match your system’s specifications.
Omyoffice Office Chair Cylinder Replacement
Omyoffice presents a heavy-duty class 4 hydraulic pneumatic piston designed for universal fit on most chairs. It features SGS and BIFMA certification for safety and durability, with a load capacity up to 1000 lbs. The cylinder spans a 5.5-inch adjustable height range, with a fully expanded height around 16.9 inches and a minimum height near 11.4 inches. Outer diameter is 2 inches, inner diameter 1.1 inches. This unit is tailored for ergonomic office setups that demand high lift capability and long service life in daily use, rather than industrial-scale hydraulic systems.
14 Inches-22 Inches Extra Long Gas Lift Cylinder
Mastery Mart offers an extra-long gas lift cylinder with an 8-inch travel range and an adjustable height spanning from 13.97 inches to 21.85 inches. The unit features a 2-inch outer diameter and a 1-1/8 inch piston shaft diameter, designed for drafting chairs and bar stools that require substantial vertical adjustment. It is built to meet Class 4 gas cylinder standards (BIFMA/ANSI) and supports up to 1000 lbs. Potential buyers should measure their chair geometry to ensure compatibility with top and bottom mountings, as well as any cable-pin interactions that may affect stroke length.
WEN WT1508 Cross Tube Hydraulic Cylinder
The WEN WT1508 features a 1.5-inch bore, 8-inch stroke, and a 1-inch rod diameter, boasting a double-acting steel-welded design capable of up to 3000 PSI. This cylinder uses an SAE-4 port (7/16 inch-20UNF), enabling straightforward connections to hydraulic hoses. It is well-suited for light-to-mid-duty hydraulic applications where compact size and reliable repetitive motion are important. When selecting this model, verify the available mounting points and the compatibility of its ports with your hydraulic system’s fittings.
WEN WT2016 Cross Tube Hydraulic Cylinder
The WEN WT2016 expands to a 2-inch bore with a 16-inch stroke and a 1.25-inch rod diameter, delivering up to 3000 PSI. It uses an SAE-6 port (9/16 inch-18UNF), offering compatibility with a broader range of hydraulic hoses and quick-connect fittings. Its steel-welded construction provides solid durability for longer duty cycles in workshop and light-industrial settings. Consider the larger bore and stroke for higher force at extended lengths, and confirm the port size matches your existing hydraulic manifold.
Buying Guide: Key Purchase Considerations
When selecting a piston or cylinder for hydraulic applications, several factors determine long-term performance and compatibility. This guide outlines important considerations from multiple perspectives, helping you balance cost, durability, and fit for your system.
- Load capacity and pressure rating: Match the working pressure (PSI) and maximum allowable pressure to your application’s peak loads. Over-specifying can improve safety, while under-specifying risks failure or leakage.
- Stroke and bore dimensions: The stroke determines travel distance, while bore size affects force output and system flow. Ensure the combination aligns with the available space and required actuation speed.
- Port sizing and compatibility: Check SAE port standards (e.g., SAE #4, #6) and thread types to ensure proper hose connections and fittings. Misfit ports can cause leaks or failed seals.
- Material and corrosion resistance: Chrome-plated pistons and steel housings help resist rust and wear in harsh environments. Consider environments with humidity, chemicals, or dust that can accelerate degradation.
- Mounting geometry and pin holes: Verify pin hole diameter and mounting style to fit your frame, brackets, or mating components. Misalignment can cause binding, wear, or leakage.
- Operational environment: Office chairs and light-duty equipment benefit from quieter operation and smoother movement, while industrial cylinders must withstand dust, vibration, and heavy loads.
- Certifications and safety: Look for BIFMA/ANSI classifications for office components and industry-standard certifications that signal compliance with safety benchmarks.
- Maintenance and replacement parts: Availability of seals, rods, and end fittings affects lifecycle cost. Choose brands with accessible service parts and clear maintenance guidance.
In applications requiring specific functionality—such as hydraulic locks, laser-tight tolerances, or extended reach—consider models that offer additional features while ensuring they fit your hydraulic circuit and control system. For office furniture, prioritize quiet operation and load stability. For industrial machinery, prioritize high PSI capacity, robust corrosion resistance, and compatible mounting.
Overall, selecting the right piston or cylinder involves balancing mechanical specifications with durability, installation feasibility, and long-term maintenance. The products highlighted above provide a range of options across portable, office, and industrial contexts to help you identify a suitable match for your needs.
