Airtac JSI Series Standard Cylinder JSI40X100FA
The AirTAC Airtac JSI Series Standard Cylinder JSI40X100FA is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 100mm 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 JSI40X100FA
Delivering 628 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable real estate on compact machinery by being noticeably shorter than an ISO 15552 unit of the same 40 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while a two-way piston seal retains grease for a long, low-friction service life. It features a G1/4 air port, an M14x1.5 rod-end thread, and adjustable air cushions at both ends.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE position switches. For sizing tasks, plan for about 377 N of real work at 0.5 MPa, which equates to lifting roughly 32 kg vertically with a 2:1 safety margin. The included FA flange mount provides a solid front-face interface for secure equipment fastening.

Where the Airtac JSI Series Standard Cylinder JSI40X100FA Is Used
Package Diverting
Pushes small cartons off a packaging line using the 628 N push force, securely mounted via the FA flange to the conveyor frame.
Small Part Clamping
Holds lightweight aluminum extrusions in place for a drilling operation, utilizing the 32 kg vertical lift equivalent for reliable holding.
Gate Actuation
Cycles a lightweight machine guard door over the 100 mm stroke, benefiting from the compact JIS profile to fit within tight enclosures.
Is the Airtac JSI Series Standard Cylinder JSI40X100FA the Right Cylinder?
When sizing this 40 mm bore unit, verify your actual load requirements against the 628 N push and 528 N pull ratings at 0.5 MPa. If your application demands less force, dropping down to a 32 mm bore provides 402 N of push, while stepping up to a 50 mm bore yields 982 N. Since this 100 mm stroke falls under the 300 mm threshold, rod-bending side-load concerns are minimal, but always ensure linear guidance for optimal seal longevity.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the end-of-stroke cushions only decelerate the piston rather than locking it. To suspend a vertical load securely, incorporate an external rod lock or a pilot-operated check valve. Also, if your machine requires end-of-stroke signaling, you must select the -S magnet variant to enable CMSE or DMSE sensors.
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 JSI40X100FA FAQ
This 40 mm bore cylinder uses a G1/4 air port and an M14x1.5 rod thread. The thrust outputs are 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, because this specific SKU does not include the -S magnet, it cannot accept CMSE or DMSE magnetic switches. You would need to select the -S variant to enable sensor grooves for position detection.
