Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75 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 JSIJ40X225-75
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features an external adjuster that shortens the on-site extend stroke by up to 75 mm. The nominal 225 mm stroke remains the maximum travel, yielding a usable 150 to 225 mm extend range while the retract end stays fixed. It handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin. An extruded hard-anodized aluminium barrel replaces traditional rods, making the body shorter and more compact than a same-bore ISO 15552 unit.
Air connects via a G1/4 port, driving the 16 mm rod at speeds of 30-800 mm/s with 20.5 mm adjustable air cushions at both ends. Because this specific SKU lacks a magnet, it cannot accept CMSE or DMSE sensors. Note that the cushions only decelerate the piston near the stroke ends; the cylinder will not hold a load on air loss, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75 Is Used
Adjustable End-Stop Clamping
Dial in the exact clamping position on varying part widths by shortening the extend stroke up to 75 mm on-site without changing the cylinder body.
Variable-Length Reject Gate
Accommodate different product sizes on a packaging line by tuning the 225 mm maximum extend down to 150 mm to deflect items precisely.
Compact Vertical Lift
Lift approximately 32 kg vertically in tight machine cells where the shorter JIS profile body saves valuable floor space compared to standard ISO units.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X225-75 the Right Cylinder?
Size this 40 mm bore against its neighbours: a 32 mm bore provides 402 N push at 0.5 MPa for lighter duties, while a 50 mm bore steps up to 982 N if your load exceeds the 377 N safe working figure. The 75 mm extend-shortening window is ideal for fine-tuning the end position on-site without swapping the cylinder, letting you standardise one spare across multiple stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. As this SKU has no magnet, you cannot mount position sensors; choose the -S variant if you require CMSE or DMSE switches. For any stroke at or above 300 mm, always use a guide rail to prevent side-load damage to the rod seals.
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 JSIJ40X225-75 FAQ
At 0.5 MPa it delivers 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 and features a 16 mm rod with an M14x1.5 thread.
An external stop screw lets you shorten the extend stroke on-site by up to 75 mm. The nominal 225 mm stroke is the maximum travel, so the usable extend range is 150 to 225 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
