Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 200mm stroke, G1/4 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40
Generating 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site flexibility to fixed-length builds. The hard-anodized aluminum profile barrel keeps the body shorter and more compact than a same-bore ISO 15552 cylinder, saving valuable machine space.
A built-in external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable range of 160 to 200 mm without changing the hardware. It handles about 377 N of safe working load, which is roughly 32 kg lifted vertically with a 2:1 margin. The unit features a G1/4 port, an M14x1.5 rod thread, and 20.5 mm adjustable air cushions at both ends. Note that this specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40 Is Used
Sorter Diverter Tuning
Dial in the exact 160 to 200 mm push-out distance on a conveyor belt diverter to accommodate varying package sizes without swapping actuators.
Clamp Position Adjustment
Fine-tune the clamping reach on a small machining fixture by shortening the extend stroke up to 40 mm to avoid deforming delicate workpieces.
Carton Flap Folding
Adjust the folding arm stroke on-site to match different carton heights, ensuring crisp folds without re-engineering the entire packaging station.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40 the Right Cylinder?
Size this 40 mm bore against its neighbors: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore jumps to 982 N. The external adjuster is ideal when you need to fine-tune the extend end position on-site or want a shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the nominal stroke is 200 mm, standard guidance applies but keep an eye on side loads. For position feedback, you must select the -S variant, as this base model cannot accept a sensor.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it delivers 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa.
The nominal 200 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, yielding a usable range of 160 to 200 mm. The retract end remains fixed. This mechanism sets the end position but does not lock the load; for holding a load on air loss, use an external rod lock or pilot-operated check valve.
