Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-100S
The AirTAC JSIJ32~50 Adjustable Cylinder JSIJ32X350-100S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø32mm bore and 350mm 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 JSIJ32X350-100S
The hard-anodized aluminum barrel keeps the overall body shorter than a same-bore ISO 15552 unit, saving valuable machine space. 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 -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 250 to 350 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder, which is ideal for sharing a spare across different stroke variants. The G1/8 port and 20 mm adjustable air cushions at both ends manage the 30-800 mm/s speed range. Note that a plain cylinder drifts on air loss; use an external rod lock or pilot-operated check valve to hold a load securely.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 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 JSIJ32~50 Adjustable Cylinder JSIJ32X350-100S Is Used
Adjustable Stop Positioning
Dial in the exact extend endpoint on a small clamping fixture by shortening the stroke from 350 mm down to 250 mm without changing the cylinder mount.
Compact Transfer Pusher
Use the space-saving JIS profile body to push light 20 kg parts between conveyor lanes, relying on the G1/8 port for fast pneumatic response.
Sensor-Ready Divert Gate
Leverage the built-in magnet and CMSE switches to confirm gate extension and retraction in automated sorting lines, ensuring reliable package routing.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ32X350-100S the Right Cylinder?
Conversely, if you are oversizing for speed, there is no smaller standard JSIJ option. The adjustable stroke is a major selection advantage when you need on-site end-position tuning or want to standardize one spare cylinder for multiple 250-350 mm stroke machines. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet equips the cylinder for CMSE/DMSE sensors. Because the stroke is 350 mm, always support the load with an external guide to prevent rod bending and excessive side loading.
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 JSIJ32X350-100S FAQ
The theoretical maximum force is 82 kgf at 1.0 MPa. The air port size is G1/8.
The 350 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 250 to 350 mm. The retract end remains fixed, and this mechanism only sets the end position; it does not lock the load.
