Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40 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 JSIJ40X225-40
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings compact air power to tight assemblies. Its extruded hard-anodized aluminum barrel is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space without losing strength. The G1/4 port feeds a double-acting single-rod mechanism rated for 30-800 mm/s speeds.
The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, yielding a usable range of 185-225 mm while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder, which is ideal for shared spares across stroke variants. In practical terms it handles about 377 N of real work, translating to roughly 32 kg lifted vertically with a 2:1 safety margin. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40 Is Used
Stopper Gate Tuning
Dial in the exact 185-225 mm extend position to deflect packages of varying widths on a conveyor without changing the physical cylinder.
Clamp Position Trimming
Trim the extend stroke by up to 40 mm on-site to perfect the clamping depth against machined parts of different heights.
Shared Spare Inventory
Keep one cylinder in stock and adjust the external stop screw to cover multiple 40 mm bore machines with slightly different extend requirements.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-40 the Right Cylinder?
When sizing, the 32 mm bore offers 402 N push at 0.5 MPa while the 50 mm jumps to 982 N, so this 40 mm bore at 628 N sits perfectly for mid-range actuation. The 40 mm adjustable window is a major advantage when you need to dial in a precise end stop on-site or want one shared spare to cover several stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 225 mm stroke exceeds 300 mm only slightly, guide any side loads carefully to prevent rod wear. Remember that a plain cylinder drifts on air loss; add an external rod lock or pilot-operated check valve if you need to hold a load securely.
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 JSIJ40X225-40 FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It features a 16 mm rod, a G1/4 port, an M14x1.5 rod thread, and 20.5 mm adjustable air cushions at both ends.
The nominal 225 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 185-225 mm. The retract end remains fixed. This stop sets the end position but does not lock the load.
