Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 500mm 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 JSIJ40X500-10
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings a compact footprint to long-stroke tasks. The extruded hard-anodized aluminum barrel leaves external tie rods out entirely, making the body shorter and cleaner than a same-bore ISO 15552 unit. It feeds through a G1/4 port and carries a 16 mm rod with an M14x1.5 thread.
The -10 code means an external adjuster can shorten the extend stroke on-site by up to 10 mm, letting you fine-tune the end position from 490 to 500 mm without swapping the cylinder. In practice it handles about 377 N of safe working load, or roughly 32 kg lifted vertically with a 2:1 margin. Because this is a non-magnet SKU, it cannot take a CMSE or DMSE sensor; add the -S variant if you need position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-10 Is Used
Conveyor Diverter
Tunes the 500 mm extend reach by 10 mm to align perfectly with shifting conveyor lanes without remounting the actuator.
Carton Push-off
Pushes packaging off a roller bed, using the adjustable stop to compensate for varying box widths on the fly.
Long-reach Forming
Extends across a wide press bed, dialing in the final 10 mm of contact pressure against a material stop.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X500-10 the Right Cylinder?
When sizing, the 32 mm bore tops out at 402 N push at 0.5 MPa while the 50 mm bore jumps to 982 N, so this 40 mm bore sits right in the middle for medium-duty cycling. The adjustable stroke is ideal for sharing a spare across similar stroke variants or dialing in a final end position on the machine. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Since the 500 mm stroke is long, always support the load with an external guide to prevent rod bending and side-load wear. Remember that a plain cylinder drifts on air loss—the cushion only decelerates, so fit an external rod lock for held loads.
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 JSIJ40X500-10 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. The air port is G1/4, the rod is 16 mm, and the adjustable cushion stroke is 20.5 mm at each end.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 490 to 500 mm. The retract end remains fixed, and this stop only sets position—it does not lock the load.
