Airtac JSI Series Standard Cylinder JSI100X150STC
The AirTAC Airtac JSI Series Standard Cylinder JSI100X150STC 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 JSI100X150STC
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X150STC is a JIS-standard double-acting profile cylinder built for heavy-duty automation. 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 two-way piston seal retains grease for long, low-friction life, while the G1/2 ports handle the high airflow needed for rapid cycling.
Because the code includes an S, this SKU has a built-in piston magnet for CMSE or DMSE switches that drop directly into the side sensor grooves. Plan for about 2356 N of real work at 0.5 MPa, which safely lifts roughly 200 kg vertically with a 2:1 margin. The 33 mm adjustable air cushions at both ends absorb end-of-stroke impact, and the TC trunnion mount provides a pivoting centerline axis for articulated mechanisms.

Where the Airtac JSI Series Standard Cylinder JSI100X150STC Is Used
Injection Mold Clamping
Supplies 3927 N of push at 0.5 MPa to secure heavy injection mold halves, leveraging the hard-anodized barrel for abrasive factory environments.
Press Ejection Systems
Uses the 150 mm stroke and 801 kgf theoretical maximum force to eject dense metal or plastic parts from hydraulic press beds rapidly.
Pallet Stopper Gates
Handles heavy pallet impacts on conveyor lines, with the TC trunnion mount allowing the cylinder body to pivot smoothly during actuation.
Is the Airtac JSI Series Standard Cylinder JSI100X150STC the Right Cylinder?
When sizing this 100 mm bore, verify your actual load against the 3927 N push and 3574 N pull ratings at 0.5 MPa. If you need less force, the 80 mm bore offers 2513 N push; stepping up to the 125 mm bore yields 6136 N. The TC trunnion mount suits pivoting loads, but remember a plain cylinder drifts when air is lost or the valve is centered. The cushions only decelerate the piston near stroke end, so fit an external rod lock or pilot-operated check valve if you must hold a vertical load safely.
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 JSI100X150STC FAQ
This 100 mm bore cylinder features a G1/2 port and an M26x1.5 rod thread. 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 TC trunnion provides a pivoting centerline mount for articulated mechanisms. Its JIS profile barrel omits external rods, making it shorter and more compact than a same-bore ISO 15552 cylinder, saving valuable space on dense machinery.
