Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X600-40
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site flexibility to long-stroke automation. The extruded hard-anodized aluminium barrel omits external rods, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
A built-in external adjuster lets you trim the extend stroke by up to 40 mm directly at the machine, giving a usable range of 560 to 600 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. The unit features a G1/4 port, an M18x1.5 rod thread, and 20.5 mm adjustable air cushions at both ends. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-40 Is Used
Conveyor Diverter Tuning
Trim the 40 mm extend window on-site to perfectly align a diverter gate without machining new hard stops.
Long-Reach Pusher
Pushes packages along a 600 mm stroke, using the adjustable end position to adapt to varying box sizes.
Vertical Pressing
Safely presses components with a 589 N working load, adjusting the bottom position for different part heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-40 the Right Cylinder?
When sizing this 50 mm bore, the neighbouring 40 mm bore gives 628 N of push at 0.5 MPa, while the larger 63 mm bore jumps to 1559 N, so this model sits right in the middle for medium-force tasks. The 40 mm adjustable window is ideal when you need to share a spare cylinder across slightly different stroke variants or fine-tune a final end position on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Since the 600 mm stroke is quite long, always use an external guide rail to prevent rod bending and side-load damage. Note that without the -S suffix, this cylinder cannot support magnetic sensing.
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 JSIJ50X600-40 FAQ
This 50 mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port and features a 20 mm piston rod with an M18x1.5 thread.
The external adjuster lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 560 to 600 mm. The nominal 600 mm stroke is the maximum, and the retract end remains fixed. This mechanism only sets the end position and does not lock the load; you need an external rod lock or pilot-operated check valve to hold a load on air loss.
