Airtac JSI Series Standard Cylinder JSI100X65S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X65S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 65mm 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 JSI100X65S
Delivering 3927 N of push force at 0.5 MPa, the AirTAC JSI100X65S is a JIS-standard double-acting profile cylinder engineered for heavy-duty automation. Its extruded hard-anodized aluminum barrel omits external rods, making the body noticeably shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The built-in piston magnet (-S) allows CMSE or DMSE reed and electronic switches to drop directly into the side grooves for precise end-of-stroke detection. A heterogeneous two-way piston seal retains grease, ensuring low-friction operation over a long service life. Air enters via the G1/2 port, driving the 32 mm chrome-plated carbon steel rod at speeds of 30-800 mm/s.
For practical sizing, plan for a safe working load of about 2356 N of real work at 0.5 MPa, which is roughly 60 percent of the rated push force. In vertical lifting applications, this translates to lifting about 200 kg with a 2:1 safety margin. Adjustable 33 mm air cushions at both ends absorb kinetic energy near the stroke limits, protecting the TPU buffer gaskets from impact damage.

Where the Airtac JSI Series Standard Cylinder JSI100X65S Is Used
Injection Mold Clamping
Provides 3927 N of clamping pressure at 0.5 MPa to secure medium-sized injection mold halves during plastic part forming.
Pallet Diverting
Uses the 65 mm stroke and built-in magnet to rapidly extend and divert heavy pallets on a packaging line at speeds up to 800 mm/s.
Press Fit Assembly
Presses bearings into heavy machinery housings, utilizing the 33 mm adjustable air cushions to soften the impact at the end of the stroke.
Is the Airtac JSI Series Standard Cylinder JSI100X65S the Right Cylinder?
When sizing this 100 mm bore model, verify your actual load against the available force. If 3927 N of push at 0.5 MPa is excessive, stepping down to the 80 mm bore yields 2513 N. If you need more power, the 125 mm bore provides 6136 N. Because this is a 65 mm stroke, side-load risks are minimal, but always ensure the rod-end M26x1.5 thread is aligned correctly with your load. Remember that a standard cylinder drifts when air is lost or the valve is centered; the air cushion only decelerates the piston near the end of stroke and does not act as a lock. For suspended loads that must be held in position, install 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 JSI100X65S 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 hard-anodized aluminum barrel without external rods, saving valuable machine space.
