Airtac JSI Series Standard Cylinder JSI100X550STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X550STC is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 550mm 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 JSI100X550STC
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an equivalent ISO 15552 unit of the same 100 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. A built-in piston magnet comes standard, allowing CMSE or DMSE reed and electronic switches to drop directly into the side grooves for position detection.
At 0.5 MPa you can plan for roughly 2356 N of real work, which translates to lifting about 200 kg vertically with a 2:1 safety margin. The G1/2 air port feeds the 32 mm hard-chrome piston rod, and adjustable 33 mm air cushions at both ends absorb end-of-stroke impact. For tasks requiring opposed or variable length strokes, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Where the Airtac JSI Series Standard Cylinder JSI100X550STC Is Used
Pallet Diversion
Pushes heavy timber pallets sideways onto a secondary line using the 3927 N thrust, with the TC trunnion absorbing the pivot stress.
Vertical Lift Gate
Raises a 180 kg loading dock gate through the 550 mm stroke, safely staying under the 200 kg vertical lift capacity.
Press Ejection
Clears stamped metal parts from a hydraulic press bed, relying on the 33 mm cushions to soften the rapid 30-800 mm/s retraction.
Is the Airtac JSI Series Standard Cylinder JSI100X550STC the Right Cylinder?
When sizing this 100 mm bore, stepping down to a JSI63 yields 1559 N of push at 0.5 MPa, while moving up to a JSI125 provides 6136 N, letting you match the exact energy requirement. This unit includes the -S magnet for sensors and uses a TC trunnion mount, which accommodates pivoting loads. Because the 550 mm stroke creates a long lever arm, use an external guide rail to prevent rod bending and premature seal wear under side loads. Remember that the air cushion only decelerates the piston near the end caps; it will not hold a suspended load if air pressure drops or the valve is centered. To prevent drifting, install an external rod lock or a pilot-operated check valve.
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 JSI100X550STC FAQ
At 0.5 MPa it provides 3927 N of push and 3574 N of pull. At 0.7 MPa the push is 5497 N and pull is 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 air port and an M26x1.5 rod thread.
No, the adjustable air cushions only decelerate the piston at the stroke ends and do not act as a brake. If air is lost or the valve is centered, the rod will drift. You must add an external rod lock or pilot-operated check valve to hold a suspended load.
