Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-50S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-50S 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 JSIJ100X100-50S
Delivering 3927 N of push force at 0.5 MPa, this 100 mm bore JIS actuator brings heavy-duty motion into a compact aluminum profile barrel that is noticeably shorter than a same-bore ISO 15552 cylinder. The G1/2 port feeds a 32 mm piston rod threaded M26x1.5, running on adjustable 33 mm air cushions at both ends. A built-in magnet equips the unit for CMSE/DMSE sensors that mount directly into the side grooves.
The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, dropping the usable forward travel from the 100 mm maximum down to 50 mm without swapping the cylinder. This on-site tuning yields a safe working load of roughly 2356 N, translating to about 200 kg of vertical lift with a 2:1 margin. The retract end remains fixed, and because the stop only sets the end position, you must add an external rod lock or pilot-operated check valve to hold a load against air loss.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-50S Is Used
Press Stroke Tuning
Dial in the exact 50 to 100 mm clamping reach on a multi-product line without machining new spacers or changing the actuator body.
Variable Transfer Stops
Adjust the extend stop on the fly to handle different carton widths on a heavy-duty belt, using the 3927 N push force to halt large payloads.
Vertical Lift Dampening
Lift approximately 200 kg of stock vertically while tweaking the upper end position to synchronize with an existing mechanical stop.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X100-50S the Right Cylinder?
When sizing this model, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter jobs, while the 125 mm bore steps up to 6136 N if you need more muscle. The 50 mm adjuster window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE switches for position feedback. For any stroke length at or above 300 mm, always use a guide rail to prevent side-load damage to the rod seals.

- ✓ 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 JSIJ100X100-50S 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 nominal 100 mm extend stroke is the maximum. The external stop screw lets you shorten the forward travel by up to 50 mm on-site, giving a usable extend range of 50 to 100 mm. The retract end is fixed, and the stop only sets position without locking the load.
