Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 100mm 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 JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS profile cylinder integrates a 20 mm external adjuster to fine-tune the extend stroke on-site. The hard-anodized aluminum barrel omits tie rods entirely, making the unit significantly shorter and more compact than a same-bore ISO 15552 cylinder. A built-in magnet (-S) allows CMSE or DMSE sensors to drop directly into the side grooves for precise position detection.
The G1/2 port feeds the double-acting single rod, which safely handles about 2356 N of real work, roughly 200 kg lifted vertically with a 2:1 margin. With a nominal 100 mm stroke, the external stop screw lets you shorten the extend travel by up to 20 mm without changing the mount, while the retract end remains fixed. Note that the adjustable air cushions only decelerate the load near the ends; an external rod lock or pilot-operated check valve is required to hold a load on air loss.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S Is Used
Press Fit Tuning
Dial in the exact 80 to 100 mm extend position for seating bearings without swapping the cylinder or adding shims.
Variable Transfer Stop
Adjust the extend stop on-site to accommodate different package widths on a 100 mm bore pneumatic routing gate.
Pallet Lift Damping
Lift roughly 200 kg vertically using the 0.5 MPa thrust while relying on the 33 mm cushions to decelerate the load smoothly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore increases it to 6136 N. The 20 mm extend-shortening window is ideal for sharing a single spare across slightly different stroke variants or dialing in an end position on the machine without machining. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The included -S magnet supports CMSE/DMSE switches. Because the stroke here is 100 mm, side loads are minimal, but any application exceeding 300 mm of travel should use a dedicated guide rail to prevent rod binding.
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 JSIJ100~125 Adjustable Cylinder JSIJ100X100-20S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. This 100 mm bore unit uses a G1/2 air port, features a 32 mm rod, and has an adjustable air cushion stroke of 33 mm at each end.
The nominal 100 mm stroke is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 80 to 100 mm. The retract end is fixed. This stop screw sets the end position and does not lock the load; you need an external rod lock for load holding.
