Airtac JSI Series Standard Cylinder JSI100X1650S
The AirTAC Airtac JSI Series Standard Cylinder JSI100X1650S is a genuine double acting JIS-standard air cylinder with a Ø100mm bore and 1650mm 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 JSI100X1650S
Delivering 3927 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder handles heavy-duty automation with ease. Its extruded hard-anodized aluminum barrel contains no external rods, making the unit shorter and more compact than an ISO 15552 cylinder of the same 100 mm bore. The built-in -S piston magnet allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
Because the 1650 mm stroke exceeds the 1500 mm standard maximum, this is a made-to-order unit. For real-world sizing, plan for about 2356 N of actual work at 0.5 MPa, which safely lifts roughly 200 kg vertically with a 2:1 margin. The internal two-way piston seal retains grease for long, low-friction life, while the G1/2 port and M26x1.5 rod thread match the bore's heavy force class.

Where the Airtac JSI Series Standard Cylinder JSI100X1650S Is Used
Automotive Body Welding
Indexes heavy welding fixtures along a 1.6-meter axis, using the 3927 N push force to clamp and position steel panels securely.
Pallet Transfer Line
Pushes loaded pallets across a wide assembly bay, where the compact JIS profile saves valuable machine footprint compared to standard ISO units.
Large Material Lift
Raises 200 kg components vertically between processing tiers, relying on external guides to stabilize the extended 1650 mm stroke.
Is the Airtac JSI Series Standard Cylinder JSI100X1650S the Right Cylinder?
When sizing this 100 mm bore actuator, consider the 80 mm option (2513 N push at 0.5 MPa) for lighter duties, or the 125 mm bore (6136 N push at 0.5 MPa) if you need maximum thrust. Since this is a plain double-acting cylinder, the piston will drift if air pressure drops or the valve is centered; the adjustable air cushion only decelerates the rod near the end of travel. To hold a suspended load securely, add an external rod lock or a pilot-operated check valve.
At 1650 mm, this non-standard stroke requires careful mounting to prevent rod bending. Always use external guide rails to support the load and minimize side-load forces on the long piston rod. The -S magnet is already included, so you can fit CMSE or DMSE switches without modifying the cylinder.
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 JSI100X1650S 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. This 100 mm bore unit uses a G1/2 air port, an M26x1.5 rod thread, and operates at 30-800 mm/s.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. The 1650 mm stroke is a non-standard, made-to-order dimension because it exceeds the 1500 mm maximum standard stroke for this bore size.
