Airtac JSI Series Standard Cylinder JSI100X240S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X240S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 240mm 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 JSI100X240S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X240S is a double-acting JIS-standard profile cylinder built for heavy machinery. Its extruded hard-anodized aluminum barrel omits external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring low-friction operation over a long service life. Equipped with a G1/2 port and a 32 mm rod, it handles dynamic loads efficiently.
For practical sizing, plan for roughly 2356 N of real work at 0.5 MPa, which safely lifts about 200 kg vertically with a 2:1 margin. 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. The adjustable 33 mm air cushions at both ends decelerate the piston smoothly near stroke end, protecting your equipment from impact.

Where the Airtac JSI Series Standard Cylinder JSI100X240S Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure heavy injection mold halves during the pressing cycle.
Pallet Dispenser Pusher
Uses the 240 mm stroke to index empty pallets into high-speed packaging lines without consuming excessive frame space.
Stamping Press Feed
Drives heavy metal blanks into a stamping press, relying on the 33 mm adjustable cushions to absorb end-of-stroke kinetic energy.
Is the Airtac JSI Series Standard Cylinder JSI100X240S the Right Cylinder?
When sizing this 100 mm bore, verify if the 80 mm bore (delivering 2513 N push at 0.5 MPa) is sufficient, or step up to the 125 mm bore (6136 N push) for heavier demands. For vertical or suspended loads, remember that a standard cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston and does not act as a lock. Install an external rod lock or pilot-operated check valve to hold the load securely. The 240 mm stroke is well within standard limits, but always ensure adequate guide support to prevent rod bending under side loads. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, and TC trunnion, plus I/Y/F/U rod knuckles.
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 JSI100X240S FAQ
This 100 mm bore cylinder features a G1/2 port and a 32 mm piston rod. It delivers 3927 N push and 3574 N pull at 0.5 MPa, 5497 N push and 5003 N pull at 0.7 MPa, with a theoretical maximum of 801 kgf at 1.0 MPa.
The JSI series follows JIS standards and uses an extruded aluminum barrel without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same bore. This space-saving design is ideal for tight machine layouts.
