Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40S 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 JSIJ40X200-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder uses a hard-anodized aluminum barrel to stay shorter and more compact than a same-bore ISO 15552 unit. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin. The G1/4 port feeds the double-acting single rod, and the -S suffix means a built-in magnet is present for CMSE/DMSE switches that drop directly into the side grooves.
The -40 code defines an external adjuster that lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 160-200 mm while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder, and the 20.5 mm adjustable air cushions at both ends decelerate the load smoothly. Remember that a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load securely.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40S Is Used
Divert Gate Tuning
Dial in the exact extend stop within the 160-200 mm window to deflect packages of varying sizes on a sorting line without changing hardware.
Clamp Positioning
Fine-tune the clamping depth on-site using the external adjuster to compensate for material thickness variations in a machining fixture.
Compact Pallet Stop
Use the shorter JIS profile to fit a 200 mm stroke stop into a tight pallet handling cell, shortening the extend stroke by 40 mm as needed.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X200-40S the Right Cylinder?
When sizing this 40 mm bore, step down to a 32 mm bore for lighter loads (402 N push at 0.5 MPa) or up to a 50 mm bore for heavier work (982 N push at 0.5 MPa). The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in end positions on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors, and for any stroke at or over 300 mm you should guide the load to prevent side-load damage.
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 JSIJ40X200-40S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 port and a 16 mm rod with an M14x1.5 thread.
The nominal 200 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable extend range of 160-200 mm. The retract end is fixed, and this stop only sets position, it does not lock the load.
