Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-20S
The AirTAC JSIJ63~80 Adjustable Cylinder JSIJ63X175-20S 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 JSIJ63X175-20S
The hard-anodized aluminum barrel skips external rods for a clean exterior, and the G3/8 port handles the air flow. Because it carries the -S suffix, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise position detection.
The -20 code means an external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable range of 155 to 175 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder, and the 29 mm adjustable air cushions at both ends absorb impact.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |

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 JSIJ63X175-20S Is Used
Press Stroke Tuning
Dial in the exact 155 to 175 mm extend reach on a light assembly press without machining new spacers, using the external adjuster to set the final contact position.
Divert Arm Positioning
Fine-tune where a divert gate rests at the end of its stroke on a packaging line, making sure product clears the belt perfectly before retracting.
Vertical Lift Stops
Lift loads up to 79 kg and tweak the upper stopping point on-site to match varying pallet heights, relying on the magnetic sensors for confirmation.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ63X175-20S the Right Cylinder?
The 20 mm adjustable window is ideal when you need to dial in a final extend position on the machine or want a single shared spare across slightly different stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Since the -S magnet is present, you are ready for CMSE/DMSE sensors. For any stroke at or above 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ63X175-20S FAQ
This 63 mm bore cylinder pushes 1559 N and pulls 1402 N at 0.5 MPa, and pushes 2182 N while pulling 1962 N at 0.7 MPa. The theoretical maximum force is 318 kgf at 1.0 MPa. It uses a G3/8 air port, an M18x1.5 rod thread, and a 20 mm piston rod.
The nominal 175 mm stroke is the maximum length. The external stop screw lets you shorten the extend stroke on-site by up to 20 mm, giving a usable extend range of 155 to 175 mm while the retract end remains fixed. This mechanism only sets the end position; it does not lock the load, so you need an external rod lock or pilot-operated check valve to hold a load on air loss.
