INTBUYING Air Cylinder SC 40 x 1000
Best for: applications that require a very long 1000 mm stroke while maintaining a solid aluminum body. The bore is 40 mm, which provides a balanced force for extended travel. This model features a double-acting design and a chrome-plated rod for durability. It is suited for automation benches, linear actuators, and material handling where extended reach is essential.
Why it’s selected: Its combination of a long stroke, standard M12X1.25 rod port, and aluminum construction offers a practical long-travel solution without overbuilding the cylinder. The data shows a range of 0.15–0.7 MPa operating pressure, making it compatible with common pneumatic systems.
Limitations: The piston speed specification (50–800 mm/s) may require system tuning to maintain consistent motion at very long strokes. Ensure mounting and guidance are optimized to avoid side loads that can affect accuracy over the full travel.
HNJPC SC Long Stroke 4″ Bore 20″ Stroke
Best for: industrial automation setups needing a sturdy 500 mm travel with a compact 100 mm bore. This double-acting model includes a magnetic piston and aluminum construction for fatigue resistance in repetitive cycles.
Why it’s selected: The 500 mm stroke offers a substantial reach while keeping the bore compact for tighter installation envelopes. The threaded PT1/2 hole and operating range of 0–145 PSI align with typical pneumatic systems in production lines.
Limitations: A 4″ bore may limit actuation force compared with larger bore options at the same pressure, so verify load requirements align with the expected force output over the stroke.
Baomain Pneumatic Air Cylinder SC 63 x 500
Best for: heavy-duty line work where a 63 mm bore is needed with a 500 mm stroke. The two push-in fittings and PT 3/8 port make it straightforward to integrate into existing pneumatic circuits.
Why it’s selected: The 2-1/2″ bore yields strong thrust for longer travels, and the M16x1.5 threaded rod supports secure connections. The self-lubricating bearing helps reduce maintenance in busy automation setups.
Limitations: Compared to larger bore cylinders, it may deliver less peak force at a given pressure; ensure the load is within its optimal range for the stroke.
Baomain Pneumatic Air Cylinder SC 63 x 400
Best for: compact long-stroke tasks where space is a constraint but a reliable 400 mm travel is still required. Suitable for pick-and-place stations and inline actuators in smaller machines.
Why it’s selected: The same robust 63 mm bore family with an ample 400 mm stroke and M16x1.5 threading provides consistent performance in mid-sized automation setups.
Limitations: The stroke length is shorter than 500 mm variants; verify that 400 mm meets the required travel distance in your application.
HNJPC SC Long Stroke 1-1/4″ Bore 12″ Stroke
Best for: compact long-stroke requirements where a small bore is advantageous. This 32 mm bore with a 300 mm stroke fits tight spaces while offering double-acting operation and magnetic piston features.
Why it’s selected: It demonstrates how long travel can be achieved even in a small-footprint cylinder, useful for modular machines and compact automation cells.
Limitations: The smaller bore yields lower thrust; confirm the load and force requirements do not exceed its capabilities.
Buying Guide: Long Stroke Air Cylinders
What to consider when choosing:
- Stroke length versus available space: Measure the required travel and compare it against installation clearance and mounting options.
- Bore size and force: A larger bore increases thrust. Balance required force with the available pneumatic pressure and cycle speed.
- Port size and fittings: Ensure compatibility with your existing pneumatic tubing (PT or G ports) and mounting patterns.
- Material and durability: Aluminum or alloy bodies offer corrosion resistance and light weight; magnet-equipped pistons aid position sensing in automation.
- Operating temperature and pressure range: Verify the cylinder can operate within your system’s temperature and pressure window.
- Maintenance needs: Self-lubricating bearings reduce upkeep; consider accessibility for routine servicing.
- Mounting and guidance: Long strokes require robust mounting and smooth linear guides to prevent side loads and misalignment.
Common configurations and tips
- Double-acting cylinders provide pushing and pulling motion, ideal for symmetrical actuation in automation cells.
- Push-in fittings simplify installation but verify tube outer diameter compatibility for a leak-free connection.
- Magnetic pistons enable position sensing with compatible sensors, improving feedback control in PLC systems.
FAQ
- What is a long stroke air cylinder good for? It is ideal when you need extended travel to reach distant workpieces, index parts along a line, or actuate large positioning tasks.
- How do I choose between 400 mm and 500 mm strokes? Pick 500 mm for greater reach and flexibility; choose 400 mm if space is limited and the stroke distance is sufficient for the task.
- Does bore size affect speed? Bore size mainly influences thrust; stroke length and system pressure govern speed. Smaller bores can move faster with the same pressure, but offer less force.
- Are magnetic pistons necessary? Magnetic pistons enable easier integration with sensing hardware, but are optional depending on your control scheme.
- What maintenance is typical? Look for self-lubricating bearings or sleeves to reduce friction and wear, and regularly inspect seals and rod for corrosion or damage.
- Can these cylinders operate in harsh temperatures? Check the specified operating temperature range for each model to ensure reliable performance in your environment.
