Airtac JSI Series Standard Cylinder JSI100X900
The AirTAC Airtac JSI Series Standard Cylinder JSI100X900 is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 900mm 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 JSI100X900
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X900 is a JIS-standard double-acting profile cylinder built for heavy-duty linear motion. 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.
At 0.5 MPa, plan for roughly 2356 N of real work, which translates to lifting about 200 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, meaning it cannot accept CMSE or DMSE position switches. Air enters via the G1/2 port, driving the 32 mm chrome-plated rod at speeds between 30 and 800 mm/s.

Where the Airtac JSI Series Standard Cylinder JSI100X900 Is Used
Automotive Body Press
Provides the 3927 N push at 0.5 MPa required to form and seat large sheet metal panels over a 900 mm travel distance.
Pallet Transfer Ejector
Pushes fully loaded heavy-duty pallets off a roller line, utilizing the full 900 mm extension to clear the conveyor zone.
High-Bay Extractor
Acts as the main extraction arm on automated storage systems, reaching deep into racking to pull out 200 kg tote bins.
Is the Airtac JSI Series Standard Cylinder JSI100X900 the Right Cylinder?
When sizing this 100 mm bore, stepping down to the JSI80X900 yields 2513 N push at 0.5 MPa, while moving up to the JSI125X900 provides 6136 N. Because this model has a 900 mm stroke, you must support the load with an external guide to prevent rod bending and excessive side loading. Note that a standard cylinder drifts when air is lost or the valve is centered; the 33 mm adjustable air cushions only decelerate the piston near the end of travel. Use an external rod lock or pilot-operated check valve if the load must be held.
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 JSI100X900 FAQ
The JSI100X900 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 air port size is G1/2.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. This saves space on machinery without sacrificing the 900 mm stroke.
