Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X450-75S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site flexibility to long-stroke automation. The external stop screw provides a 75 mm adjustment window, allowing you to shorten the extend stroke anywhere from 450 mm down to 375 mm without changing the hardware. It handles about 377 N of real work, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. The -S suffix means a built-in piston magnet is included for side-groove CMSE or DMSE sensors. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends. Remember that the cushion only slows movement; an external rod lock or pilot-operated check valve is required to hold a load securely on air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75S Is Used
Divert Gate Tuning
Fine-tunes the extend position of a sorting diverter by up to 75 mm on-site to accommodate different package sizes without swapping the entire cylinder.
Variable Stop Positioning
Acts as an adjustable physical stop for incoming pallets, letting operators dial back the full 450 mm extension to match changing pallet footprints.
Press Stroke Adjustment
Provides a 375 to 450 mm downward stroke for light pressing tasks, enabling precise height calibration directly at the machine rather than via software.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75S the Right Cylinder?
When sizing this actuator, compare it against neighbouring bores: a 32 mm bore offers 402 N push at 0.5 MPa for lighter duties, while a 50 mm bore provides 982 N if your load grows. The 75 mm adjustable window is highly useful for sharing a single spare cylinder across multiple stroke variants or fine-tuning the end position during machine commissioning. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this model has a 450 mm stroke, always support the load with an external guide to prevent rod bending and excessive side loading. The integrated magnet supports CMSE/DMSE switches for position feedback.

- ✓ 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 JSIJ40X450-75S FAQ
At 0.5 MPa it delivers 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. The air port size is G1/4.
An external stop screw lets you shorten the extend stroke by up to 75 mm on-site. The usable extend range is 375 mm to the 450 mm maximum, while the retract end remains fixed. This mechanism sets the end position and does not lock the load.
