Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-30 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 JSIJ40X225-30
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 withstanding industrial wear. It operates on a G1/4 port and features a 16 mm rod with an M14x1.5 thread.
The -30 code means an external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 195 to 225 mm without changing the cylinder itself. This on-site tuning is ideal for dialing in exact end positions. It handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin. Note this SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-30 Is Used
Conveyor Diverter Tuning
Dial in the exact pusher extension by up to 30 mm on-site to deflect varying package sizes without swapping the cylinder.
Clamp Position Adjustment
Fine-tune the clamping endpoint on machining fixtures where part tolerances require a slightly shorter forward stroke.
Compact Stacking Push
Fit a shorter JIS-profile actuator into tight palletizing cells and adjust the extend reach to match different layer heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-30 the Right Cylinder?
When sizing, the 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm bore jumps to 982 N if you need more force. This 40 mm bore hits a solid middle ground with 628 N push and 528 N pull at 0.5 MPa. The adjustable stroke is useful when you need to fine-tune the extend end position on the machine or want a shared spare across slightly different stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 225 mm stroke exceeds 300 mm, always use a guide rail to prevent side-load damage. Since this is a no-magnet SKU, you cannot add position sensors.
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 JSIJ40X225-30 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. This 40 mm bore cylinder uses a G1/4 air port.
The external stop screw lets you shorten the extend stroke on-site by up to 30 mm. The usable extend range is 195 to 225 mm, with the 225 mm nominal stroke being the maximum. The retract end is fixed. This mechanism only sets the end position and does not hold the load; use an external rod lock or pilot-operated check valve for load holding.
