Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X160-20
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X160-20 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 160mm 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 JSIJ100X160-20
The extruded hard-anodized aluminum barrel leaves no external tie rods, making the unit measurably shorter than an equivalent ISO 15552 cylinder of the same bore.
The -20 code defines an external adjuster that lets you shorten the extend stroke on site by up to 20 mm, giving a usable forward travel of 140 to 160 mm while the retract end stays fixed. You fine-tune the end position without swapping the cylinder. Air connects via a G1/2 port, and the rod end uses an M26x1.5 thread. Note that this specific SKU lacks a magnet, so it cannot accept CMSE or DMSE sensors.

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 JSIJ100X160-20 Is Used
Press Tonnage Trimming
Dial in the exact 140 mm extend stop on-site to seat bearings without bottoming out the full 160 mm travel.
Pallet Positioning Stop
Absorb heavy pallet impacts using the 3574 N pull force, adjusting the forward position by up to 20 mm as line layouts change.
Heavy Diverter Gate
Shift dense packages with 5497 N at 0.7 MPa, using the external adjuster to tune the gate drop distance precisely.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X160-20 the Right Cylinder?
When sizing this 100 mm bore, stepping down to an 80 mm cylinder drops the 0.5 MPa push force to 2513 N, while moving up to a 125 mm bore raises it to 6136 N. The adjustable stroke is ideal for sharing a single spare across multiple stroke variants or dialing in a precise end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this SKU has no -S suffix, it cannot host a magnetic switch; add the -S variant for CMSE/DMSE sensing. For any stroke at or over 300 mm, always guide the load to prevent 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 JSIJ100X160-20 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 is 801 kgf at 1.0 MPa. It uses a G1/2 port, an M26x1.5 rod thread, and a 33 mm adjustable air cushion at each end.
The nominal extend stroke is 160 mm, but an external stop screw lets you shorten that forward travel by up to 20 mm on site, yielding a usable range of 140 to 160 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load against air loss.
