Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 100mm stroke, G1/4 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 JSIJ40X100-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder uses an external adjuster to shorten the extend stroke on-site by up to 40 mm. The nominal 100 mm stroke remains the maximum travel, yielding a usable 60-100 mm extend range while the retract end stays fixed. It carries a built-in magnet for CMSE/DMSE sensors and features a G1/4 port.
Built with an extruded hard-anodized aluminum barrel, the unit is shorter and more compact than a same-bore ISO 15552 cylinder. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin. Note that the adjustable stop sets end position only; the cushion decelerates but does not lock, so fit an external rod lock or pilot-operated check valve for held loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-40S Is Used
End-Position Trimming
Fine-tune the extend stop on a clamping fixture by up to 40 mm without swapping the cylinder, dialing in the exact grip on varying part widths.
Transfer Stroke Adjustment
Shorten the 100 mm extend stroke on a push-off conveyor diverter to 60 mm on-site, adapting the travel distance to a new lane layout.
Spare Consolidation
Keep one adjustable unit as a plant-wide spare for multiple 40 mm bore actuators, setting the extend window to match the required stroke during installation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-40S the Right Cylinder?
Size this 40 mm bore against the 32 mm option when you need more than the 402 N @0.5 MPa push of the smaller size, or step up to the 50 mm bore for 982 N @0.5 MPa. The -40 mm adjustable window is ideal for on-site end-position tuning or sharing a spare across stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S suffix means a piston magnet is present for CMSE/DMSE sensors. 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 JSIJ32~50 Adjustable Cylinder JSIJ40X100-40S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. The air port is G1/4.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm. With a 100 mm nominal maximum stroke, the usable extend range is 60-100 mm. The retract end is fixed, and the stop sets position only without locking the load.
