Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-100
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø63mm 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 JSIJ63X175-100
The nominal 175 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its extruded hard-anodized aluminium barrel omits tie rods entirely, creating a cleaner, more compact body that is notably shorter than a same-bore ISO 15552 cylinder. The G3/8 port feeds the 20 mm piston rod for rapid cycling.
You can dial the usable extend stroke down to 75 mm for precise machinery setup. Remember that a plain unit cannot hold a load on air loss—the adjustable cushion only decelerates near the end of travel, so fit an external rod lock or pilot-operated check valve for suspended loads. This specific SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 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 JSIJ63~80 Adjustable Cylinder JSIJ63X175-100 Is Used
Machine Tool Clamping
Dial in the exact clamping reach on a machining fixture by shortening the 175 mm extend stroke up to 100 mm, accommodating different part heights without changing cylinders.
Pallet Stopper Tuning
Fine-tune the stopping position of pallets on a roller bed by turning the external adjuster, setting the stroke anywhere from 75 to 175 mm as line layouts evolve.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-100 the Right Cylinder?
The 100 mm adjuster window is especially useful for sharing a single spare cylinder across multiple stroke variants in a plant, as you can tune the extend end position on the floor. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnetized SKU, it cannot accept position sensors; choose the -S variant if you require CMSE or DMSE switches. For this 175 mm stroke, ensure adequate guide support to prevent side-loading damage to the M18x1.5 rod thread.
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 JSIJ63X175-100 FAQ
This 63 mm bore cylinder pushes with 1559 N and pulls with 1402 N at 0.5 MPa. At 0.7 MPa, push is 2182 N and pull is 1962 N. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 air port and features a 20 mm piston rod with an M18x1.5 thread.
The -100 code means an external stop screw lets you shorten the extend stroke by up to 100 mm on-site. The nominal 175 mm stroke is the maximum travel, so the usable extend range is 75 to 175 mm. The retract end remains fixed, and the stop mechanism sets the end position but does not lock the load.
