Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X50-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X50-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 50mm 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 JSIJ40X50-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder uses an external adjuster to shorten the extend stroke on site. The hard-anodized aluminum barrel keeps the body more compact than a same-bore ISO 15552 unit. It handles about 377 N of real work, which is roughly 32 kg lifted vertically with a 2:1 margin.
The -50 code means you can trim the extend stroke by up to 50 mm, dropping the usable forward travel from the 50 mm maximum down to zero. A fixed retract end sets the back position, while the adjustable air cushions of 20.5 mm decelerate the piston smoothly. This base SKU lacks a magnet and cannot take a CMSE or DMSE sensor. Air connects via a G1/4 port.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X50-50 Is Used
Clamp Position Tuning
Dial in the exact clamping reach on a machining fixture by trimming the extend stroke up to 50 mm without swapping cylinders.
Transfer Gate Stop
Set a precise product stop position on a conveyor line, adjusting the forward travel window to handle different package sizes.
Light Press Fit
Execute short press operations for small component seating, using the adjustable stop to control the final insertion depth.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X50-50 the Right Cylinder?
For lighter tasks the 32 mm bore gives 402 N push at 0.5 MPa, while stepping up to the 50 mm bore yields 982 N. This 40 mm bore generates 628 N push and 528 N pull at 0.5 MPa, making it a solid mid-range choice. The 50 mm adjustment window is ideal when you need to fine-tune an end position without remounting hardware, or when sharing a spare cylinder across slightly different stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a non-magnet version, position sensing is unavailable. For any stroke at or over 300 mm, always guide the load to prevent side-load damage.
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 JSIJ40X50-50 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. It features a 16 mm rod, M14x1.5 rod thread, G1/4 port, and 20.5 mm adjustable cushions.
The 50 mm nominal stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke on site by up to 50 mm, reducing usable travel to zero if needed. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
