Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 75mm 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 JSIJ40X75-10S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminum extruded barrel keeps the assembly light, while the G1/4 port matches the bore standard.
The external stop screw provides a 10 mm on-site extend-shortening window, letting you fine-tune the end position down to a 65 mm usable stroke without swapping the cylinder. It handles about 377 N of safe working load, translating to roughly 32 kg lifted vertically with a 2:1 margin. The integrated -S magnet supports CMSE/DMSE sensors in the side grooves for position feedback.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-10S Is Used
Clamp Stroke Tuning
Dial in the exact 65 to 75 mm clamping reach on-site using the external adjuster to accommodate varying workpiece thicknesses without remounting.
Sensor-Equipped Ejection
Use the built-in magnet with CMSE/DMSE switches to confirm part ejection in tight assembly cells where the compact JIS profile saves valuable space.
Transfer Pusher Adjustment
Fine-tune the pusher end-position by up to 10 mm to handle different product sizes on a packaging line while maintaining a safe 377 N working load.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X75-10S the Right Cylinder?
Size this 40 mm bore against the 32 mm option (402 N push at 0.5 MPa) for lighter duties, or step up to the 50 mm class (982 N push) when you need 1374 N at 0.7 MPa. The adjustable 10 mm window is ideal for sharing one spare across slightly different stroke variants and tuning end positions on-site. Choose from Basic, FA, LB, TC, TCM1, or TCM2 mounts. The -S magnet enables CMSE/DMSE switches. For any stroke over 300 mm, add an external guide to prevent side-load 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 JSIJ40X75-10S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it delivers 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 rod is 16 mm with an M14x1.5 thread, and it has 20.5 mm adjustable air cushions at both ends.
The nominal 75 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable extend range of 65 to 75 mm for precise end-position tuning. The retract end is fixed. Note that this stop only sets position; it does not hold the load on air loss, so you need an external rod lock or pilot-operated check valve for holding.
