TAILONZ PNEUMATIC 25mm Bore 150mm Stroke Double Action
This double-acting cylinder offers a 25mm bore and a 150mm stroke, providing substantial linear reach in compact form. The PT1/8 port size supports quick installation with common pneumatic fittings, and the single-rod design keeps weight down for precise control. It is well suited for automation tasks requiring both extension and retraction forces at moderate speeds, with a rated maximum pressure around 145 psi.
TAILONZ PNEUMATIC 32mm Bore 50mm Stroke Double-Rod Cylinder
This model features a 32mm bore with a short 50mm stroke and a robust aluminum body. The double-rod design increases stability and stroke guidance, making it suitable for precise repeatable movements in compact automation lines. Port size is 1/8 NPT, and operating pressure ranges from 0 to 145 psi, matching typical factory air systems.
TAILONZ PNEUMATIC 32mm Bore 75mm Stroke Double-Rod
With a longer 75mm stroke, this double-rod cylinder extends reach while maintaining a compact 32mm bore. The aluminum build offers strength with reduced weight, and the unit uses a 1/8 NPT port for easy integration into standard pneumatic lines. It supports a similar working pressure range, enabling versatile operation in automation setups requiring extended travel.
TAILONZ PNEUMATIC 20mm Bore 50mm Stroke Double-Rod
This compact unit uses a 20mm bore with a 50mm stroke and a double-rod configuration. The PT1/8 port size aligns with common pneumatic hardware, and the operating pressure falls within the standard range for most small- to mid-scale automation tasks. The design emphasizes smooth actuation and stable returns, suitable for precise positioning and clamping applications.
TAILONZ PNEUMATIC 20mm Bore 100mm Stroke Double-Acting
This long-stroke option provides 100mm of travel in a lightweight 20mm bore cylinder. The aluminum construction ensures durability in repeated cycles, and the model includes a Y-connector and fittings for immediate integration into a pneumatic circuit. With a maximum pressure around 145 psi, it suits feed- or pick-and-place operations where additional stroke is advantageous.
HNJPC SC Air Cylinder 50mm x 75mm
HNJPC’s SC series cylinder offers a 50mm bore and 75mm stroke in a robust aluminum body. A PT1/4 threaded hole and a 0-145 psi operating window make it a strong choice for general automation tasks requiring reliable linear motion with moderate force. The unit’s design focuses on factory-ready mounting and consistent performance in industrial environments.
HNJPC MAL Mini 16mm Bore 25mm Stroke
Designed for compact automation tasks, the MAL mini cylinder has a 16mm bore and 25mm stroke. It uses a compact aluminum body with a small footprint and M5 mounting threads. The unit operates within a typical pneumatic range, making it suitable for tight spaces, precision clamping, and light-duty actuation in machine-builds or hobby projects.
Baomain Pneumatic SC 63 x 150
Baomain’s SC 63 x 150 model provides a 63mm bore and a 150mm stroke in a double-acting configuration. The PT3/8 port size and M16X1.5 piston port size suit heavier automation tasks, while the single-rod design helps reduce lateral movement during operation. This option is appropriate for conveyor lines and fixtures requiring robust actuation with extended travel.
Buying Guide: Key Considerations For Your Selection
- Application load and speed: Larger bores deliver more force; longer strokes translate to greater travel. Match bore and stroke to your mechanical load and cycle rate.
- Port and mounting compatibility: Check port sizes (PT1/8, 1/8 NPT, PT1/4) and mounting threads to ensure seamless integration with existing sensors, valves, and brackets.
- Material and wear: Aluminum bodies offer light weight and corrosion resistance, while some variants use more compact, low-profile housings suitable for tight spaces.
- Operating pressure range: Most models accommodate 0-145 psi. Ensure your compressor, valves, and air supply can sustain sustained operation within this window.
- Double-acting vs. single-rod configurations: Double-acting cylinders provide push and pull movements; double-rod variants improve alignment and return stability, especially in precise applications.
- Environmental conditions: Temperature tolerance matters for outdoor or industrial settings. Watch for articles specifying operating temperatures and seals material.
- Maintenance and accessories: Look for included fittings, connectors, or Y-connectors, and confirm availability of replacement seals for long-term reliability.
- Cost of integration: Compare ease of installation, added accessories, and compatibility with existing control systems to estimate total cost of ownership.
In selecting a double-acting pneumatic cylinder, consider the specific motion profile, space constraints, and system air supply. The options above provide a range of bore sizes, strokes, and port configurations to fit common American automation tasks—from compact inline actuators to longer-travel fixtures. When in doubt, prioritize units with widely available fittings and clear documentation to minimize setup time and ensure dependable performance in production environments.
