Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 450mm 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 JSIJ50X450-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to long-trroke automation. The external stop screw provides a 100 mm adjustment window, letting you fine-tune the usable extend stroke anywhere from 350 mm up to the 450 mm maximum without swapping the actuator. Because the retract end remains fixed, only the forward end position shifts. This built-in adjustability makes the unit an ideal shared spare across multiple stroke variants, cutting inventory complexity.
Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. The G1/4 port feeds the dual-end adjustable air cushions, while the -S suffix denotes a built-in piston magnet for drop-in CMSE/DMSE reed or electronic sensors. In practical terms, it handles about 589 N of safe working load, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Note that the cushion only decelerates the moving mass; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100S Is Used
Transfer Line Diverter
Dial in the 350 to 450 mm extend stroke on-site to push products across varying conveyor widths without changing the cylinder.
Adjustable Push-Off Arm
Use the 100 mm external stop window to fine-tune the final ejection position for different pallet sizes in a packaging cell.
Long-Reach Vertical Lift
Lift up to 50 kg safely with the 2:1 margin, relying on the adjustable cushion to decelerate the 450 mm downstroke smoothly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100S the Right Cylinder?
When sizing this actuator, look at both neighboring bores: a 40 mm bore gives 628 N push at 0.5 MPa for lighter duties, while a 63 mm bore jumps to 1559 N for heavier demands. The 100 mm adjustable window is invaluable for dialing in exact end positions on-site or accommodating multiple machine setups with a single shared spare. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S magnet supports CMSE/DMSE sensors for position confirmation. Because the 450 mm stroke is relatively long, always guide the load externally to prevent rod bending and 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 JSIJ50X450-100S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. This 50 mm bore model uses a G1/4 air port and features a 20.5 mm adjustable air cushion at each end.
The nominal 450 mm stroke is the maximum extend length. The external adjuster lets you shorten the forward stroke by up to 100 mm on-site, giving a usable extend range of 350 to 450 mm. The retract end position stays fixed, and the adjuster sets the end stop but does not lock or hold the load.
