Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X500-75 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 500mm 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 JSIJ100X500-75
The hard-anodized aluminum profile barrel keeps the overall body more compact than a same-bore ISO 15552 cylinder.
The external stop screw provides a 75 mm adjustment window, letting you shorten the extend stroke from its 500 mm maximum down to 425 mm without changing the cylinder itself. Retract remains fixed. Air flows through a G1/2 port, and adjustable cushions at both ends absorb kinetic energy. This plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor; for load holding on air loss, add an external rod lock or pilot-operated check valve, as the cushion only decelerates.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75 Is Used
Press Stroke Tuning
Dial in the exact 425-500 mm extend reach on a light assembly press without machining new hard stops.
Variable Transfer Pusher
Adjust the pusher end position on-site to handle different pallet sizes without swapping the actuator.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X500-75 the Right Cylinder?
The 75 mm adjustable window is ideal when you need to fine-tune the extend end position across multiple stations or share a spare cylinder among 425-500 mm stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 500 mm stroke is long, always support the rod against side loads with an external guide to prevent bending. Note this non-magnetic version cannot accept position sensors.
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 JSIJ100X500-75 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. It uses a G1/2 port and a 33 mm adjustable cushion at each end.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable extend range of 425-500 mm. The retract end is fixed, and this stop sets position only—it does not lock the load.
