Airtac JSI Series Standard Cylinder JSI100X150
The AirTAC Airtac JSI Series Standard Cylinder JSI100X150 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 JSI100X150
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X150 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 noticeably shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The internal two-way piston seal retains grease, ensuring long, low-friction service life even under demanding cycles. Because this specific SKU lacks the -S magnet suffix, it cannot accept CMSE or DMSE position switches without upgrading to the sensed variant.
For practical sizing, plan for about 2356 N of real work at 0.5 MPa, which safely lifts about 200 kg vertically with a 2:1 margin. The 32 mm carbon steel rod is hard-chrome plated for wear resistance, and the body features G1/2 ports alongside 33 mm adjustable air cushions at both ends to smooth out end-of-stroke impacts. If your machine requires dual opposing rods or a custom stroke length, consider the related JSID or JSIJ series.

Where the Airtac JSI Series Standard Cylinder JSI100X150 Is Used
Automotive Body Welding
Clamps heavy steel chassis panels with 3927 N of push force at 0.5 MPa, holding parts firmly for robotic spot welding guns.
Pallet Diverting
Pushes loaded 150 mm stroke diverters to shift heavy pallets between adjacent high-speed packaging conveyor lines.
Vacuum Forming Press
Closes large plastic sheet molds, using the 33 mm adjustable air cushions to prevent impact damage at the end of the stroke.
Is the Airtac JSI Series Standard Cylinder JSI100X150 the Right Cylinder?
When sizing this 100 mm bore, stepping down to the JSI80X150 yields 2513 N of push force at 0.5 MPa, while stepping up to the JSI125X150 provides 6136 N. At 150 mm of stroke, side-load risks are minimal, but always ensure rigid mounting using the FA or FB flange, LB foot, or TC trunnion options to prevent rod binding. Remember that a standard cylinder drifts when air is lost or the valve is centered; the adjustable cushion only decelerates the piston near the end caps and will not hold a load. For vertical applications requiring position holding, integrate an external rod lock or a pilot-operated check valve.
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 JSI100X150 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. It uses a G1/2 air port and an M26x1.5 rod thread.
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, saving valuable machine space. Note that this specific SKU lacks a magnet, so it cannot host CMSE or DMSE sensors without the -S option.
