Luftzylinder Double Acting Air Cylinder
This aluminum round-tube air cylinder emphasizes durability and long-lasting performance. The design suits a wide range of industrial equipment, including machinery manufacturing, automotive applications, and shipyard equipment. The product highlights premium aluminum construction and broad applicability, making it a versatile choice for shops seeking robust, reliable pneumatic actuation.
TAILONZ PNEUMATIC 25mm Bore 150mm Stroke Air Cylinder Double Action
With a 25 mm bore and a long 150 mm stroke, this double-acting cylinder provides extended reach and strong retraction force. The PT1/8 port size is standard for many pneumatic systems, and the included Y-connector and fittings offer straightforward installation in line with common automation setups.
TAILONZ PNEUMATIC 20mm Bore 50mm Stroke Double-Rod
This double-rod double-acting cylinder is designed for compact spaces while delivering reliable linear motion. The 20 mm bore and 50 mm stroke make it suitable for light automation tasks, gripping mechanisms, and pulling or pushing actions in constrained environments. The PT1/8 port keeps compatibility with many air lines and valves.
TAILONZ PNEUMATIC 32mm Bore 75mm Stroke Double-Rod
Featuring a 32 mm bore and a 75 mm stroke, this double-rod configuration balances force and stroke length for mid-range automation tasks. The 1/8 NPT port size aligns with standard pneumatic fittings, enabling easy integration into existing systems. It is suitable for applications requiring stable thrust and compact form factor.
HNJPC MAL Mini Pneumatic Cylinder MAL16x25
This compact aluminum air cylinder uses a 16 mm bore and a 25 mm stroke, ideal for tight spaces and small-scale automation. It supports a temperature range and an air pressure range that suit lightweight, precise actuation tasks. The miniature scale makes it a good choice for end-effector movements or compact tooling assemblies.
Buying Guide
Key considerations influence performance, durability, and compatibility when selecting a double acting air cylinder. The following perspectives cover practical criteria and usage scenarios.
- Bore and stroke: Larger bores deliver higher thrust; longer strokes extend travel. Match bore and stroke to the required force and movement range, while considering system speed limits and rod fatigue through repetitive cycles.
- Rod design: Single-rod vs. double-rod configurations affect balance and alignment. Double-rod cylinders tend to offer smoother action and better resistance to side loads, which is helpful for guided motions.
- Port size and fittings: Common sizes include PT1/8 and 1/8 NPT. Ensure compatibility with existing valves, manifolds, and tubing. Check for included connectors or adapters to reduce setup time.
- Material and durability: Aluminum cylinders provide light weight and corrosion resistance. For aggressive environments, consider models with seals suitable for temperature and contaminants present in the application.
- Operating pressure and temperature: Verify the maximum operating pressure and temperature range. Applications involving heat, moisture, or particulates may require additional protection or seals.
- Mounting options: Look for end-plate configurations and mounting holes compatible with your machinery. Some cylinders include integrated mounting hardware for quicker installation.
- Maintenance and replacement parts: Availability of seals, rods, and end caps influences total cost of ownership. Choose suppliers with readily available spare parts and documented service intervals.
- System integration: Ensure the cylinder’s stroke and force align with your actuator, sensor, and control logic. Consider double-acting cylinders when positive push and pull motion is needed for synchronized operations.
- Cost of ownership: Evaluate durability, replacement part availability, and service life in your environment. Sometimes a slightly higher upfront cost yields longer service intervals and lower downtime.
- Application examples: Packaging, fixture actuation, material handling, and automated clamping are common uses. Consider whether you need a compact unit for tight spaces or a longer stroke for extended reach.
For robust automation tasks with steady repeatable motion, fixed double-acting cylinders with durable aluminum construction and standard porting offer dependable performance. When space is limited, compact mini cylinders provide precise actuation with a smaller footprint. For applications requiring longer strokes or multi-directional control, multi-rod configurations deliver balanced thrust and stroke alignment. Always verify compatibility with your pneumatic valves, manifolds, and control system to ensure smooth operation and easy maintenance.
