Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-30 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 JSIJ40X900-30
Generating 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for on-site stroke tuning. A hard-anodized aluminum extrusion forms the barrel, making the body shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds the double-acting single-rod system, driving a 16 mm rod with M14x1.5 end threads.
The external adjuster lets you shorten the extend stroke by up to 30 mm, giving a usable range of 870-900 mm without swapping the cylinder. It handles about 377 N of safe working load, roughly 32 kg lifted vertically with a 2:1 margin. This SKU lacks a magnet and cannot take a CMSE/DMSE sensor. Note that the 20.5 mm air cushions only decelerate the piston; they do not hold the load on air loss, so fit an external rod lock for vertical safety.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-30 Is Used
Long-Reach Diverting
Tunes the 870-900 mm extend stop to match varying pallet widths on a transfer line without changing hardware.
High-Bay Pusher
Uses the compact JIS profile to save axial space while pushing totes, relying on an external guide for the 900 mm span.
Carton Stopper
Adjusts the 30 mm window on-site to synchronize the end-stop position with different box lengths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-30 the Right Cylinder?
Size this 40 mm bore against the 32 mm and 50 mm options. The 32 mm yields 402 N push at 0.5 MPa, while the 50 mm jumps to 982 N, so this model sits perfectly for mid-range duties. The adjustable 870-900 mm window is ideal when you need to fine-tune a long end-position across multiple machines or keep one shared spare. Choose from Basic, FA, LB, TC, TCM1, or TCM2 mounts. Because this is a 900 mm stroke, always use an external guide to prevent rod bending and side-load damage. Without the -S suffix, this version cannot host magnetic sensors.
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 JSIJ40X900-30 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 is 128 kgf at 1.0 MPa. It uses a G1/4 air port, a 16 mm rod, M14x1.5 rod threads, and 20.5 mm adjustable cushions.
The 900 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 870-900 mm. The retract end remains fixed. This stop sets the end position and is not a load lock.
