Airtac JSI Series Standard Cylinder JSI40X100TC
The AirTAC Airtac JSI Series Standard Cylinder JSI40X100TC 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 JSI40X100TC
Generating 628 N of push force at 0.5 MPa, this double-acting 40 mm bore cylinder is built for tight machinery layouts. As a JIS-standard profile unit, it is notably shorter and more compact than an equivalent ISO 15552 cylinder of the same bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches. For sizing real tasks, plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The unit features a G1/4 air port, an M14x1.5 rod thread, and 20.5 mm adjustable air cushions at both ends to smooth out stroke transitions.

Where the Airtac JSI Series Standard Cylinder JSI40X100TC Is Used
Package Diverter
Actuates a routing gate on a packaging conveyor, using the 100 mm stroke to push cartons into secondary lanes without consuming excessive frame depth.
Small Part Ejection
Ejects molded plastic components from an injection press, leveraging the 528 N pull force at 0.5 MPa to reliably retract a stripper plate.
Clamp Actuation
Drives a secondary clamping jaw on a CNC machining center, where the compact JIS profile leaves room for adjacent tooling and chip clearance.
Is the Airtac JSI Series Standard Cylinder JSI40X100TC the Right Cylinder?
If 628 N of push at 0.5 MPa is excessive for your application, the smaller JSI32 bore offers 402 N; conversely, stepping up to the JSI50 provides 982 N. This 100 mm stroke model is supplied with a TC trunnion mount, giving you a pivot axis suited to articulated mechanisms. Remember that a standard cylinder will drift if air pressure drops or the valve centers, as the end cushions only decelerate the piston rather than locking it. To suspend a load safely mid-stroke, integrate an external rod lock or a pilot-operated check valve into your pneumatic circuit.
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 JSI40X100TC FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum is 128 kgf at 1.0 MPa. The air port is G1/4.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSE or DMSE switches. You would need the JSI40X100TC-S variant to enable magnetic sensing.
