Airtac JSI Series Standard Cylinder JSI40X200
The AirTAC Airtac JSI Series Standard Cylinder JSI40X200 is a genuine double acting 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 JSI Series Standard Cylinder JSI40X200
Generating 628 N of push force at 0.5 MPa, this double-acting 40 mm bore cylinder is built around an extruded hard-anodized aluminum barrel. Because it follows a JIS-standard profile architecture, the body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable real estate on tight machinery. The internal two-way piston seal retains grease for a long, low-friction service life.
With a 200 mm stroke and a G1/4 air port, it delivers a practical safe working load of about 377 N—roughly 60 percent of its 0.5 MPa rating. That translates to lifting around 32 kg vertically with a 2:1 safety margin. Note that this specific SKU lacks the -S magnet, so it cannot host CMSE or DMSE position switches in its side grooves.

Where the Airtac JSI Series Standard Cylinder JSI40X200 Is Used
Package Diverting
Pushes small cartons off a sorting line using a 200 mm travel, relying on the 628 N push force to overcome box friction.
Pallet Tagging
Extends a pneumatic label applicator 200 mm toward incoming pallets, fitting into tight conveyor gaps thanks to the compact profile.
Small Press Ejection
Kicks lightweight stamped aluminum parts out of a die area, where the hard-anodized barrel withstands repetitive cycling.
Is the Airtac JSI Series Standard Cylinder JSI40X200 the Right Cylinder?
If 628 N of push is excessive for your payload, dropping down to the 32 mm bore yields 402 N at 0.5 MPa. Conversely, if you need more authority, the 50 mm bore provides 982 N. This 200 mm stroke is well within the 1200 mm maximum, but at lengths of 300 mm or more you should guide the rod to prevent bending under side loads. Since this SKU has no -S magnet, sensing is impossible without changing to the magnet-equipped variant.
Keep in mind that standard double-acting operation does not secure the load if air pressure drops or the valve is centered; the piston will drift. The adjustable 20.5 mm cushions merely decelerate the piston near the end caps, so install an external rod lock or pilot-operated check valve if you need to hold a vertical load safely.
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 JSI Series Standard Cylinder JSI40X200 FAQ
The 40 mm bore uses a G1/4 port and a 16 mm rod with an M14x1.5 thread. It generates 628 N push and 528 N pull at 0.5 MPa, 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so CMSE or DMSE switches cannot be used. You would need the -S variant for position sensing.
