Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-30
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm 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 JSIJ100~125 Adjustable Cylinder JSIJ125X1000-30
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS actuator brings heavy-duty motion into a compact hard-anodized aluminium profile barrel that is physically shorter than a same-bore ISO 15552 cylinder. The G1/2 port feeds a 32 mm rod running on adjustable 33 mm air cushions at both ends.
An external stop screw lets you trim the extend stroke by up to 30 mm on site, giving a usable 970-1000 mm forward travel while the retract end stays fixed. This on-site tuning means you can fine-tune the end position without changing the cylinder, and it handles about 3682 N of real work, roughly 313 kg lifted vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-30 Is Used
Heavy Press Tampening
Adjust the 30 mm window on site to set the exact 970 mm down-stroke for tamping heavy assemblies without swapping the actuator.
Pallet Stopper Finesse
Trim the extend end-position by a few millimeters to perfectly match varying pallet widths on a high-force 125 mm conveyor line.
Large Mold Clearance
Shorten the forward stroke from the 1000 mm maximum to safely clear large molds during changeovers, relying on the 8590 N push at 0.7 MPa.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X1000-30 the Right Cylinder?
Size both ways against the 125 mm bore: drop to a 100 mm bore if you only need 3927 N push at 0.5 MPa, or stay here at the top edge for 6136 N. The -30 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end-position tuning on site. Mount using FA, LB, TC, TCM1, or TCM2 brackets. Because this is a no-S SKU, it cannot accept magnetic sensors. With a 1000 mm stroke, always use an external guide to prevent rod bending and side-load damage.
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 JSIJ125X1000-30 FAQ
It provides 6136 N push and 5734 N pull at 0.5 MPa, 8590 N push and 8028 N pull at 0.7 MPa, with a theoretical max of 1251 kgf at 1.0 MPa. The air port is G1/2.
The nominal 1000 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on site by up to 30 mm, yielding a usable 970-1000 mm forward travel. The retract end is fixed, and this stop is for positioning, not load holding.
