Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 450mm 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 JSIJ100X450-50S
The hard-anodized aluminium extruded body is noticeably more compact than a same-bore ISO 15552 unit. A G1/2 port feeds the chamber, while the -S suffix adds a piston magnet for CMSE or DMSE switches.
The external adjuster lets you fine-tune the extend end position anywhere between 400 and 450 mm without swapping the cylinder, leaving the retract end fixed. Adjustable air cushions of 33 mm at each end absorb kinetic energy, but they only decelerate the piston and do not lock the load. For vertical or suspended loads that must hold position on air loss, fit an external rod lock or pilot-operated check valve.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |
| 0.7 MPa | 4935 N | 4935 N |
| Max (@1.0 MPa) | 719 kgf | |
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 JSIJ100X450-50S Is Used
Press Stroke Tuning
Dial in the exact 400 to 450 mm extend contact point on a light assembly press without machining new spacers.
Divertor Arm Adjustment
Fine-tune the pusher extension length on a sorting line to handle different carton widths on the fly.
Pallet Stop Positioning
Set a precise end stop for heavy pallets, using the 50 mm window to adjust the resting location easily.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-50S the Right Cylinder?
The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in a final end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet enables side-groove sensor mounting. Because the stroke is 450 mm, always support the load with external guides 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 JSIJ100X450-50S 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.
The 450 mm nominal stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable range of 400 to 450 mm. The retract end remains fixed.
