Airtac JSI Series Standard Cylinder JSI100X50STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X50STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 50mm stroke, G1/2 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 JSI100X50STC
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore cylinder is built for heavy-duty positioning. As a JIS-standard profile unit, it is notably shorter and more compact than an equivalent ISO 15552 cylinder, saving valuable machine space without sacrificing power. 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 SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing. Plan for roughly 2356 N of real work at 0.5 MPa, which translates to lifting about 200 kg vertically with a 2:1 safety margin. The unit features a G1/2 port, an M26x1.5 rod thread, and 33 mm adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSI Series Standard Cylinder JSI100X50STC Is Used
Injection Mold Clamping
Provides the high clamping thrust needed to secure heavy injection mold halves, utilizing the 3927 N push force to hold the tooling steady during the injection cycle.
Pallet Stopper Gate
Acts as a robust stopper arm on heavy-duty pallet conveyors, extending quickly to halt 200 kg loads before they enter a wrapping or labeling station.
Press Die Ejection
Ejects dense stamped metal parts from a hydraulic press, using the 33 mm adjustable air cushions to prevent end-of-stroke impact on the machine frame.
Is the Airtac JSI Series Standard Cylinder JSI100X50STC the Right Cylinder?
This 100 mm bore sits between the JSI63 (1402 N pull at 0.5 MPa) and the JSI125 (5734 N pull at 0.5 MPa), giving you a clear upgrade path if your force requirements shift. The included TC trunnion mount allows pivoting articulation, which is ideal for accommodating slight misalignments in your mechanical linkage. Since this specific configuration carries the -S suffix, it is fully ready for CMSE or DMSE sensor installation.
Remember that a standard pneumatic cylinder cannot hold a load if air pressure drops or the valve is centered; the piston will drift, as the air cushions only decelerate the rod near the stroke ends and do not act as a brake. To suspend a load safely, integrate an external rod lock or a pilot-operated check valve into your 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 JSI100X50STC FAQ
This 100 mm bore model uses a G1/2 port and generates a push force of 3927 N and a pull force of 3574 N at 0.5 MPa. At 0.7 MPa, the push is 5497 N and the pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, helping you save footprint on tight machinery. It features a hard-anodized aluminum barrel with no external rods, and this specific -S SKU includes a piston magnet for side-groove CMSE or DMSE sensors.
