Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 80mm stroke, G1/8 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 JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S
The hard-anodized aluminum barrel keeps the assembly light, while the G1/8 port feeds the 12 mm rod. Because it carries the -S suffix, a built-in piston magnet is present, ready to accept CMSE or DMSE reed and electronic switches that drop directly into the side grooves.
The -20 code means an external adjuster can shorten the extend stroke on site by up to 20 mm, dropping the usable forward travel from the 80 mm maximum down to 60 mm without swapping the cylinder. The retract end remains fixed. Note that a plain cylinder drifts on air loss; the air cushion only decelerates near the end, so fit an external rod lock or pilot-operated check valve if you need to hold a load.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S Is Used
Gauge Position Trimming
Use the 20 mm extend adjuster to dial in the exact forward reach of a 60 to 80 mm gauging probe without machining new spacers.
Small Part Ejection
Times the 32 mm bore push stroke for lightweight plastic ejector pins where 402 N at 0.5 MPa is more than enough force.
Shared Spare Inventory
Keep one -S cylinder on the shelf and adjust the forward stop from 60 to 80 mm to service multiple similar machine stations.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S the Right Cylinder?
When sizing, step down from a 40 mm bore if your 0.5 MPa load is under 345 N pull, or step up if you exceed the 32 mm push capacity. The adjustable stroke shines when you need to fine-tune the extend end position on the machine or want a single shared spare across slightly different stroke variants. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. The -S magnet equips the cylinder for position sensing. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the front cover.
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 JSIJ32~50 Adjustable Cylinder JSIJ32X80-20S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port is G1/8.
The 80 mm nominal stroke is the maximum forward travel. The -20 code provides an external adjuster that lets you shorten the extend stroke on site by up to 20 mm, giving a usable extend range of 60 to 80 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
