Airtac JSI Series Standard Cylinder JSI40X200STC
The AirTAC Airtac JSI Series Standard Cylinder JSI40X200STC 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 JSI40X200STC
Delivering 628 N of push force at 0.5 MPa, the AirTAC JSI40X200STC is a double-acting 40 mm bore JIS-standard profile cylinder engineered for tight machinery layouts. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same bore, yielding a tangible space saving without sacrificing output. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the heterogeneous two-way piston seal retains grease for extended, low-friction service life.
Because the SKU includes the -S suffix, a built-in piston magnet enables drop-in CMSE or DMSE reed and electronic switches along the side grooves for precise end-of-stroke detection. For practical sizing, 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 unit features a G1/4 port, an M14x1.5 rod thread, and adjustable air cushions at both ends to smoothly decelerate the 200 mm travel.

Where the Airtac JSI Series Standard Cylinder JSI40X200STC Is Used
Package Diverters
Actuates routing flaps on 30-800 mm/s packaging lines to sort small parcels, utilizing the 628 N push force to snap gates shut rapidly.
Palletizer Stops
Deploys a 200 mm stroke mechanical stop to halt empty pallets at the loading station, absorbing kinetic energy via the adjustable end cushions.
Small Press Ejectors
Pushes lightweight aluminum castings out of a 40-ton benchtop press, relying on the compact JIS profile to fit within the machine's narrow column gap.
Is the Airtac JSI Series Standard Cylinder JSI40X200STC the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm JSI drops the output to 402 N push at 0.5 MPa, whereas moving up to a 50 mm bore raises it to 982 N if your fixture requires more muscle. The included TC trunnion mount provides a pivoting interface that accommodates slight misalignment, and the -S magnet ensures immediate compatibility with position sensing. Because this model features a 200 mm stroke, maintaining adequate guide bushing support on the external load is recommended to prevent excessive rod bending and premature seal wear.
Remember that a standard double-acting cylinder drifts when air is lost or the valve is centered, as the adjustable cushion only decelerates the piston near stroke end rather than locking it. To safely suspend a load vertically, 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 JSI40X200STC FAQ
This 40 mm bore cylinder provides 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. The air port is G1/4, the rod thread is M14x1.5, and the adjustable air cushion stroke is 20.5 mm at each end.
The TC trunnion mount allows the cylinder body to pivot during operation, compensating for alignment shifts. Furthermore, the JIS-standard extruded profile is physically shorter and more compact than a same-bore ISO 15552 cylinder, saving valuable real estate on dense equipment frames.
