Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 900mm 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 JSIJ40X900-10
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings compact air power to long-stroke tasks. Its extruded hard-anodized aluminum barrel omits external rods, making the overall body shorter than an ISO 15552 cylinder of the same bore. The G1/4 port feeds a double-acting single-rod design rated for 30-800 mm/s.
The -10 code defines an external adjuster that lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 890-900 mm for fine end-position tuning without swapping parts. In practice it handles about 377 N of real work, roughly 32 kg lifted vertically with a 2:1 margin. Note this plain SKU lacks a magnet and cannot take CMSE/DMSE sensors; add an -S variant for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-10 Is Used
Transfer Push-Off
Pushes parts off a long conveyor belt, using the 10 mm adjuster to dial the exact eject distance without moving the cylinder.
High-Bay Divert
Actuates a divert flap at the end of a 900 mm reach, fine-tuning the extended flap angle on site to match package sizes.
Long Lowering Stop
Lowers a light tooling head 900 mm, adjusting the final bottom stop by 10 mm to compensate for varying material thickness.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-10 the Right Cylinder?
This 40 mm bore sits between the lighter 32 mm (402 N push at 0.5 MPa) and the heavier 50 mm (982 N), giving you a clear upgrade path if loads shift. The 10 mm adjustable window is ideal for sharing a spare across stroke variants or dialing in a final stop. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke invites rod sag, always use an external guide to prevent side-load bending. Remember this no-S version cannot host a sensor.
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 JSIJ40X900-10 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it yields 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 port, a 16 mm rod with an M14x1.5 thread, and 20.5 mm adjustable air cushions at both ends.
The nominal 900 mm stroke is the maximum. The external -10 adjuster lets you shorten the extend stroke by up to 10 mm on site, yielding a usable range of 890-900 mm. The retract end is fixed. This mechanism sets the end position and decelerates the load, but it does not hold the load on air loss; use an external rod lock or pilot-operated check valve for that.
