Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-30
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X50-30 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 50mm 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 JSIJ100X50-30
The extruded hard-anodized aluminium barrel is noticeably shorter than an ISO 15552 cylinder of the same bore. A G1/2 port feeds the double-acting double rod, while adjustable air cushions of 33 mm decelerate the payload at each end.
The -30 code means an external adjuster can shorten the extend stroke on-site by up to 30 mm, giving a usable forward travel of 20 to 50 mm without changing the hardware. This on-site end-position tuning is ideal for shared spares across stroke variants. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |

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 JSIJ100X50-30 Is Used
Press Fit Tuning
Fine-tune the 20 to 50 mm extend stroke on-site to set precise insertion depth for bearing presses without swapping the actuator.
Pallet Stopper Gate
Act as a heavy pallet stop where the 30 mm shortening window lets operators adjust the gate drop height to match new product sizes.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-30 the Right Cylinder?
This model shines when you need on-site end-position tuning across machines sharing the same spare parts. The JSIJ mounting set includes Basic, FA, LB, TC, TCM1 and TCM2 options. Because the 50 mm stroke is short, side-load risk is minimal, but for any stroke over 300 mm you should guide the rod to prevent binding. Add the -S suffix variant if you need CMSE or DMSE magnetic sensing, as this base unit cannot accept a switch.
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 JSIJ100X50-30 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 air cushion at each end.
The nominal 50 mm extend stroke is the maximum. The external adjuster lets you shorten the forward travel on-site by up to 30 mm, yielding a usable extend range of 20 to 50 mm. The retract end is fixed. This stop sets the end position but does not lock the load; for holding on air loss use an external rod lock or pilot-operated check valve.
