Airtac JSI Series Standard Cylinder JSI100X1000S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1000S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1000mm 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 JSI100X1000S
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an equivalent ISO 15552 unit of the same 100 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. Equipped with a G1/2 port and an M26x1.5 rod thread, it operates at speeds between 30 and 800 mm/s.
Because the SKU includes the -S suffix, a built-in piston magnet enables CMSE or DMSE switches to drop directly into the side grooves for position sensing. For real-world sizing, plan for roughly 2356 N of actual work at 0.5 MPa, which translates to lifting about 200 kg vertically with a 2:1 safety margin.

Where the Airtac JSI Series Standard Cylinder JSI100X1000S Is Used
Pallet Transfer Line
Pushes heavy loaded pallets between machining centers using its 3927 N thrust, while the 1000 mm stroke accommodates wide conveyor gaps.
Vertical Material Lift
Hoists 200 kg component racks between floor levels, relying on the -S magnet to confirm the upper and lower landing positions.
Injection Mold Ejection
Actuates large mold ejection plates over a 1-meter depth, using the hard-anodized barrel to withstand repetitive industrial impacts.
Is the Airtac JSI Series Standard Cylinder JSI100X1000S the Right Cylinder?
When sizing this 100 mm bore against its neighbors, stepping down to an 80 mm JSI drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. If your machine requires the piston to stay put after a power or air loss, remember that a standard cylinder will drift under load when the valve centers; the 33 mm adjustable air cushions only decelerate the rod near the end of travel, so you must add an external rod lock or a pilot-operated check valve for secure holding.
At a 1000 mm stroke, the 32 mm diameter piston rod is highly susceptible to bending under side loads. Always use external guide rails to support the load and prevent rod deflection over this extended travel distance.
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 JSI100X1000S FAQ
This 100 mm bore model uses a G1/2 port and an M26x1.5 rod thread. The thrust output is 3927 N push and 3574 N pull at 0.5 MPa, increasing to 5497 N push and 5003 N pull at 0.7 MPa. The theoretical maximum force at 1.0 MPa is 801 kgf.
Built to JIS standards with an extruded profile barrel, it is shorter and more compact than an ISO 15552 cylinder of the same bore. The adjustable cushions only decelerate the piston near stroke ends and do not act as a brake; the cylinder will drift if air is lost, so an external rod lock is required for position holding.
