Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 80mm 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 JSIJ40X80-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend tuning to compact automation. Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body shorter and more compact than an ISO 15552 cylinder of the same bore. The G1/4 port and M14x1.5 rod thread keep pneumatic and mounting integration simple.
The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, so the usable extension runs 30 to 80 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder, which is ideal for sharing a spare across stroke variants. In practical terms it handles about 377 N of real work, roughly 32 kg lifted vertically with a 2:1 margin. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-50 Is Used
Clamp Stroke Trimming
Dial in the exact 30 to 80 mm clamping reach on-site via the external adjuster to accommodate varying part thicknesses without changing the cylinder.
Compact Divert Stopper
Use the shortened JIS profile body to fit tight transfer lines, adjusting the stop pin extension up to 50 mm to handle different box sizes.
Shared Spare Assembly
Stock one cylinder for multiple 40 mm bore machines, tuning the extend end position on the floor to match each specific 30 to 80 mm stroke requirement.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X80-50 the Right Cylinder?
Size this 40 mm bore against its neighbours: a 32 mm bore yields 402 N push at 0.5 MPa, while a 50 mm bore jumps to 982 N. The adjustable -50 mm window shines when you need on-site end-position tuning or want a single shared spare across slight stroke variants. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU has no -S suffix, it cannot accept a magnetic sensor. For any stroke at or over 300 mm, guide the load externally to prevent rod 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 JSIJ40X80-50 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. It uses a G1/4 port.
The nominal 80 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extension range of 30 to 80 mm. The retract end is fixed. This mechanism sets the end position and is not a load lock.
