Airtac JSI Series Standard Cylinder JSI40X100CA
The AirTAC Airtac JSI Series Standard Cylinder JSI40X100CA 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 JSI40X100CA
Generating 628 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder is purposefully shorter and more compact than an equivalent 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. Air connects via a G1/4 port, and the unit features a 20.5 mm adjustable air cushion at both ends.
Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSE or DMSE position switches. For sizing practicality, 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 CA clevis mount supplied is ideal for pivoting articulations.

Where the Airtac JSI Series Standard Cylinder JSI40X100CA Is Used
Package Diverter Arm
Actuates a swinging gate on a packaging line to sort medium-weight cartons, utilizing the 100 mm stroke and CA clevis for smooth pivoting motion.
Small Part Ejection
Pushes molded plastic components out of a press die, relying on the 628 N push force to reliably clear the tooling within a short cycle time.
Clamp Mechanism
Secures aluminum extrusions in a machining fixture, applying consistent holding pressure against the workpiece before a cutting operation begins.
Is the Airtac JSI Series Standard Cylinder JSI40X100CA the Right Cylinder?
When sizing this 40 mm bore, verify your force needs against the 628 N push rating at 0.5 MPa. If your application requires less power, dropping down to a 32 mm bore yields 402 N, whereas stepping up to a 50 mm bore provides 982 N. Keep in mind that a standard cylinder drifts if air pressure is lost or the valve is centered; the cushion only decelerates the piston near stroke end rather than locking it. To suspend a load safely, incorporate an external rod lock or a pilot-operated check valve.
The included CA clevis mount accommodates angular movement, and you can pair the M14x1.5 rod thread with an I, Y, F, or U knuckle. Since this configuration has no -S magnet, you must select a magnet-equipped variant if your control system requires CMSE or DMSE sensor feedback.
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 JSI40X100CA FAQ
This 40 mm bore cylinder features a G1/4 air port and an M14x1.5 rod thread. The thrust output is 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa. The theoretical maximum force is 128 kgf at 1.0 MPa.
No, because this specific SKU does not include the -S magnet option, it cannot accept CMSE or DMSE magnetic switches. You would need to select the -S variant of this JIS profile cylinder to enable sensor feedback in the side grooves.
