Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X60-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X60-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 60mm 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 JSIJ50X60-40
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features a 60 mm nominal extend stroke that can be shortened on-site by up to 40 mm. The external adjuster allows you to fine-tune the usable extend stroke anywhere between 20 and 60 mm without swapping the cylinder, while the retract end remains fixed. This on-site adaptability means you can dial in the exact end position for a specific task and safely handle a real working load of about 589 N, which equates to lifting roughly 50 kg vertically with a 2:1 safety margin.
Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. It uses a G1/4 air port and a 20 mm piston rod. Note that this specific SKU lacks a magnet and cannot accept CMSE or DMSE sensors; for position feedback you would need the -S variant. The adjustable air cushions only decelerate the piston near the stroke ends and do not hold the load, so an external rod lock or pilot-operated check valve is required for any drop-prevention needs.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X60-40 Is Used
Short-Stroke Clamping
Dial in the exact 20 to 60 mm extend reach to clamp delicate workpieces without over-traveling and damaging the part.
Transfer Diverter
Fine-tune the pusher length on-site to accommodate different box sizes on a packaging line using the 40 mm adjustment window.
Compact Lift Stop
Leverage the shorter JIS profile to fit a 50 kg vertical lift stop into tight machine cells where ISO 15552 bodies will not fit.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X60-40 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore raises it to 1559 N. The adjustable-stroke mechanism is highly useful when you need to share one spare cylinder across several stroke variants or trim the extend end-position on the machine. You can mount it using basic, FA, LB, TC, TCM1, or TCM2 brackets. Because this SKU has no -S magnet, it cannot support magnetic sensing. For any application approaching or exceeding a 300 mm stroke, always guide the load to prevent rod side-loading.
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 JSIJ50X60-40 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4.
The nominal stroke is 60 mm. The external adjuster allows you to shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 20 to 60 mm. The retract end is fixed, and the stop only sets the end position rather than locking the load.
