Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 225mm 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 JSIJ40X225-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS actuator brings on-site flexibility to your fixturing. The hard-anodized aluminum profile barrel keeps the total length shorter than a same-bore ISO 15552 cylinder, while the integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for position detection.
The external stop screw provides a 40 mm adjustment window, letting you trim the usable extend stroke anywhere from 185 mm up to the 225 mm maximum without swapping the cylinder. It handles a safe working load of roughly 377 N, which translates to lifting about 32 kg vertically with a 2:1 safety margin. Pneumatic connections use a G1/4 port, and the retract end remains fixed.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40S Is Used
Clamp Stroke Tuning
Dial in the exact 185 to 225 mm extend reach on machining fixtures to accommodate varying part widths without changing cylinders.
Transfer Gate Adjust
Fine-tune the divert distance on a conveyor sorting line by shortening the extend stroke on-site to handle different package sizes.
Vertical Lift Stop
Lift approximately 32 kg of goods vertically and use the external adjuster to set a precise upper stop position safely.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40S the Right Cylinder?
Size this 40 mm bore against its neighbours: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore jumps to 982 N. The adjustable stroke shines when you need to fine-tune end positions across multiple stations or want a shared spare for slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The built-in magnet supports CMSE/DMSE switches. Because the 225 mm stroke exceeds 300 mm only slightly, side-load guiding is recommended for long rod extension to prevent premature seal wear.
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 JSIJ40X225-40S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull force. 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 size is G1/4.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm. The usable extend range is 185 to 225 mm, with 225 mm being the maximum nominal stroke. The retract end is fixed. This mechanism 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.
