Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 175mm stroke, G3/8 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 JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to heavy pneumatic tasks. The hard-anodized aluminum barrel uses no tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work safely, which translates to lifting roughly 128 kg vertically with a 2:1 margin.
The -30 code means an external adjuster can shorten the extend stroke by up to 30 mm, giving a usable range of 145 to 175 mm while the retract end stays fixed. You fine-tune the end position mechanically without swapping the cylinder. This -S SKU includes a piston magnet for CMSE/DMSE sensors that drop into the side grooves, and the air connection is a G3/8 port.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S Is Used
Press Stroke Tuning
Dial in the exact 145 to 175 mm extend reach on a light assembly press without machining new spacers or changing the cylinder.
Transfer Diverter
Set a precise extend stop to push heavy pallets onto a secondary line, using the 2513 N push force to move the load reliably.
Vertical Lift Gate
Lift a 128 kg gate using the 2:1 safety margin, adjusting the extend window to match the exact gate travel distance required.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa, while the 100 mm bore jumps to 3927 N, so the 80 mm sits right in the middle for medium-heavy duty. The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in a final end position on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this unit has the -S suffix, it accepts CMSE/DMSE sensors; a no-S SKU cannot take a sensor. For any stroke at or over 300 mm, always use a guide rail 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 JSIJ63~80 Adjustable Cylinder JSIJ80X175-30S FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum force is 513 kgf at 1.0 MPa. The air port is G3/8, the rod is 25 mm, and the cushion is 29 mm.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable range of 145 to 175 mm. The retract end is fixed. This stop sets the end position and does not lock the load; for load holding on air loss, use an external rod lock or pilot-operated check valve.
