Airtac JSI Series Standard Cylinder JSI100X135S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X135S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 135mm 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 JSI100X135S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X135S is a double-acting JIS-standard profile cylinder built for heavy machinery. Its extruded hard-anodized aluminum barrel omits external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The heterogeneous two-way piston seal retains grease for long, low-friction life, while the included -S piston magnet allows CMSE or DMSE sensors to drop directly into the side grooves for position detection.
This 135 mm stroke unit features a 32 mm carbon steel rod with an M26x1.5 thread, a G1/2 air port, and 33 mm adjustable air cushions at both ends to decelerate the piston smoothly. Plan for about 2356 N of real work at 0.5 MPa, which translates to lifting roughly 200 kg vertically with a 2:1 safety margin. Operating speeds span 30-800 mm/s across a 0.15-1.0 MPa pressure range.

Where the Airtac JSI Series Standard Cylinder JSI100X135S Is Used
Injection Mold Clamping
Provides 3927 N of push at 0.5 MPa to secure mid-sized injection mold halves, utilizing the compact profile to save valuable machine footprint.
Heavy Pallet Diverting
Shifts loaded pallets along high-throughput packaging lines, with the 33 mm air cushions absorbing the kinetic energy of heavy moving masses.
Vertical Material Lift
Lifts roughly 200 kg of raw materials vertically with a 2:1 safety margin, using the -S magnet to trigger upper and lower limit sensors.
Is the Airtac JSI Series Standard Cylinder JSI100X135S the Right Cylinder?
If you need slightly less force, the 80 mm bore offers 2513 N push at 0.5 MPa; for heavier demands, the 125 mm bore provides 6136 N. Since this 135 mm stroke is under 300 mm, rod bending is less of a concern, but always guide the load to prevent side loads. Remember that air cushions only decelerate the piston near the end of stroke—they do not act as a brake. If the machine loses air, the piston will drift, so fit an external rod lock or pilot-operated check valve for secure load holding. The built-in magnet on this -S model is required for CMSE/DMSE switches.
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 JSI100X135S FAQ
At 0.5 MPa it provides 3927 N push and 3574 N pull. At 0.7 MPa it provides 5497 N push and 5003 N pull. The theoretical maximum force is 801 kgf at 1.0 MPa. The air port size is G1/2.
The JSI 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 without external rods, and the -S suffix means it includes a magnet for CMSE/DMSE sensors.
