Airtac JSI Series Standard Cylinder JSI100X210S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X210S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 210mm 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 JSI100X210S
Delivering 3927 N of push force at 0.5 MPa, this double-acting 100 mm bore cylinder is built for heavy-duty automation. The JSI100X210S uses a JIS-standard extruded hard-anodized aluminum profile that is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable machine space. Its two-way piston seal retains grease for long, low-friction life, and the integrated -S magnet allows CMSE or DMSE switches to drop directly into the side grooves for position sensing.
Featuring a 210 mm stroke and a G1/2 air port, it provides a safe working load of about 2356 N for real-world tasks, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. The 32 mm hard-chrome rod and 33 mm adjustable air cushions at both ends absorb impact energy effectively. For jobs needing opposing stroke ends or adjustable length, consider the related JSID double-rod or JSIJ adjustable-stroke variants.

Where the Airtac JSI Series Standard Cylinder JSI100X210S Is Used
Injection Mold Clamping
Supplies the 3927 N push force needed to secure heavy injection mold halves, utilizing the 210 mm stroke to clear large part ejection zones.
Pallet Dispenser Pusher
Indexes empty pallets into high-speed packaging lines, where the compact JIS profile saves footprint and the -S magnet confirms dispatch via sensors.
Heavy Press Feed
Feeds thick steel blanks into a hydraulic press, relying on the 33 mm adjustable air cushions to halt the 100 mm piston smoothly at stroke end.
Is the Airtac JSI Series Standard Cylinder JSI100X210S the Right Cylinder?
When sizing this 100 mm bore model, the smaller JSI80 yields 2513 N push at 0.5 MPa, while the larger JSI125 provides 6136 N, letting you step up or down precisely. Because the 210 mm stroke exceeds 300 mm, ensure external guide rails are used to prevent rod bending under heavy side loads. Remember that a standard cylinder drifts if air pressure drops or the valve is centered; the cushions only decelerate the piston near stroke ends and do not act as a lock. For suspended loads, install an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, and TC trunnion styles.
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 JSI100X210S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum is 801 kgf at 1.0 MPa. The air port is G1/2.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. It uses an extruded aluminum barrel with no external rods, and the built-in -S magnet supports CMSE/DMSE switches.
