Airtac JSI Series Standard Cylinder JSI100X150S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X150S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 150mm 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 JSI100X150S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X150S is a double-acting JIS-standard profile cylinder built for heavy-duty automation. Its extruded hard-anodized aluminum barrel omits external rods, making the unit significantly shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. A heterogeneous two-way piston seal retains grease for long, low-friction life, while the -S suffix denotes a built-in magnet for position sensing.
The G1/2 air ports feed a 32 mm carbon steel rod that generates 3574 N of pull force at 0.5 MPa. For practical sizing, plan for about 2356 N of real work at that pressure, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. CMSE or DMSE electronic switches drop directly into the side sensor grooves, and adjustable 33 mm air cushions at both ends decelerate the piston smoothly across its 30-800 mm/s speed range.

Where the Airtac JSI Series Standard Cylinder JSI100X150S Is Used
Injection Mold Clamping
Provides the 3927 N push force required to secure mid-sized injection mold halves, utilizing the compact profile to fit within tight press enclosures.
Pallet Dispenser Pusher
Indexes empty pallets into a packaging line, easily handling loads up to 200 kg vertically with the 150 mm stroke and integrated -S magnet for position confirmation.
Heavy Press Ejection
Ejects dense stamped metal parts from a hydraulic press, relying on the 3574 N pull force and 33 mm adjustable air cushions to prevent end-of-stroke impact damage.
Is the Airtac JSI Series Standard Cylinder JSI100X150S the Right Cylinder?
When sizing this 100 mm bore, verify if the 80 mm class (delivering 2513 N push at 0.5 MPa) is sufficient, or if you need to step up to the 125 mm bore (6136 N push at 0.5 MPa) for heavier loads. The 150 mm stroke is well within standard limits, so no side-load guide concerns apply here. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, and TC/TCM1/TCM2 trunnion styles.
Because this is a double-acting cylinder, air drives both extension and retraction. The adjustable cushions only decelerate the piston near stroke end and do not function as a brake. If your application must hold a vertical load when air pressure drops or the valve is centered, add an external rod lock or a pilot-operated check valve to prevent drifting.
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 JSI100X150S FAQ
This 100 mm bore cylinder features G1/2 air ports and an M26x1.5 rod thread. It generates 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 is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable space on machinery. It is not dimensionally interchangeable with ISO 15552, but uses the same hard-anodized aluminum extrusion concept without external rods.
