Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 600mm 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 JSIJ40X600-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic unit handles about 377 N of safe working load, lifting roughly 32 kg vertically with a 2:1 margin. The hard-anodized aluminium profile barrel keeps the body more compact and shorter than a same-bore ISO 15552 cylinder, while the G1/4 port manages air flow efficiently.
An external adjuster allows you to shorten the extend stroke on-site by up to 50 mm, giving a usable range of 550-600 mm without changing the cylinder itself. This on-site tuning is perfect for dialing in exact end positions, and the 20.5 mm adjustable air cushions at both ends decelerate the piston smoothly. Note that this SKU lacks a magnet and cannot take a CMSE/DMSE sensor; for the -S variant adds a magnet for CMSE/DMSE.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50 Is Used
Conveyor Diverter Tuning
Fine-tune the 550-600 mm extend reach on-site to perfectly deflect varying package widths on a sorting line without swapping the actuator.
Vertical Lift Stop
Lifts approximately 32 kg loads vertically using the 628 N push force, with the external adjuster setting the exact raise height.
Press Positioning
Sets a precise 550 mm working gap for light assembly presses, using the 50 mm shortening window to adapt to different part heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-50 the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore increases it to 982 N. The 50 mm extend-shortening window is highly useful when you need to share a spare cylinder across slightly different stroke variants or fine-tune the end position after mechanical installation. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the 600 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage. Without a -S suffix, this SKU cannot take a magnetic 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 JSIJ40X600-50 FAQ
At 0.5 MPa it provides 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 is G1/4, the rod is 16 mm with an M14x1.5 thread, and it features 20.5 mm adjustable cushions.
The nominal 600 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, yielding a usable range of 550-600 mm. The retract end remains fixed. This stop only sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve to hold a load.
