Airtac JSI Series Standard Cylinder JSI100X225S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X225S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 225mm 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 JSI100X225S
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore JIS-standard profile cylinder is purpose-built for heavy-duty automation. Because it uses an extruded hard-anodized aluminum barrel instead of external rods, the overall body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore. The internal two-way piston seal retains grease, ensuring long, low-friction operation even under demanding cycles.
The built-in -S piston magnet allows CMSE or DMSE switches to drop directly into the side sensor grooves for precise position detection. With a practical safe working load of about 2356 N, it can reliably lift roughly 200 kg vertically with a 2:1 safety margin. Pneumatic connections use a G1/2 port, and the unit operates smoothly across a 30-800 mm/s speed range.

Where the Airtac JSI Series Standard Cylinder JSI100X225S Is Used
Injection Mold Clamping
Provides the 3927 N push force needed to secure heavy injection mold halves or actuate large core pulls during thermoplastic processing.
Pallet Dispenser Pusher
Indexes empty or loaded wooden pallets along a roller conveyor, utilizing the 225 mm stroke to clear the machine envelope efficiently.
Heavy Press Fit Assembly
Drives large bushings or bearings into automotive housings, relying on the adjustable 33 mm air cushions to prevent end-of-stroke impact damage.
Is the Airtac JSI Series Standard Cylinder JSI100X225S the Right Cylinder?
When sizing this 100 mm bore unit against adjacent models, note the JSI80 provides 2513 N of push at 0.5 MPa, while the JSI125 jumps to 6136 N. Choose the 100 mm bore when your application requires the 3927 N output to move substantial mass without stepping up to the larger 125 mm footprint. The included -S magnet pairs perfectly with CMSE/DMSE sensors for end-of-stroke confirmation.
Remember that a standard pneumatic cylinder does not hold its load if air pressure drops or the valve is centered, as the piston will drift and the end cushions only decelerate motion near stroke limits rather than acting as a brake. For suspended or vertical loads that must remain fixed during an air loss event, incorporate an external rod lock or a pilot-operated check valve into your circuit design.
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 JSI100X225S FAQ
This 100 mm bore cylinder features a G1/2 air port and an M26x1.5 rod thread. The thrust output is 3927 N push and 3574 N pull at 0.5 MPa, increasing to 5497 N push and 5003 N pull at 0.7 MPa. The theoretical maximum force at 1.0 MPa is 801 kgf.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. It achieves this by using an extruded hard-anodized aluminum barrel without external tie rods, while still offering standard mounting options like FA flange and TC trunnion.
