Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X160-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X160-40 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 160mm 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 JSIJ50X160-40
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 40 mm. The nominal 160 mm stroke acts as the maximum, yielding a usable extend range of 120 to 160 mm, while the retract end remains fixed. You can fine-tune the end position without swapping the cylinder. Built with an extruded hard-anodized aluminum barrel, the body is 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.
Air connects via a G1/4 port, driving a 20 mm piston rod with an M18x1.5 thread at speeds of 30-800 mm/s. Adjustable air cushions of 20.5 mm at each end absorb impact. This SKU lacks a magnet and cannot take a sensor; adding the -S variant enables CMSE/DMSE switches. Note that a plain cylinder drifts on air loss, as the cushion only decelerates. For a held load, install an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X160-40 Is Used
Adjustable End-Stop Clamping
Dial in the exact clamping position on varying part heights by shortening the extend stroke up to 40 mm without changing the cylinder mount.
Transfer Line Diverter
Fine-tune the diverting arm reach on-site to accommodate different box widths, using the 50 mm bore to push packages with 982 N at 0.5 MPa.
Vertical Lift Stop
Set a precise upper lift limit for 50 kg loads, relying on the external adjuster rather than machining hard stops.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X160-40 the Right Cylinder?
When sizing this 50 mm bore, compare it against the 40 mm bore (628 N push at 0.5 MPa) for lighter duties, or step up to the 63 mm bore (1559 N push at 0.5 MPa) if your application needs more power. The -40 mm adjustable window is ideal for sharing a spare across stroke variants or finalizing end-position tuning on-site. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is a no-magnet SKU, it cannot accept position sensors; select the -S version if you require CMSE/DMSE switches. For any stroke length of 300 mm or more, always use a guide rail to prevent excessive side-loading on the rod.
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 JSIJ50X160-40 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it yields 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port, a 20 mm rod, an M18x1.5 rod thread, and 20.5 mm adjustable cushions at both ends.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm. With a nominal 160 mm maximum stroke, the usable extend range becomes 120 to 160 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load.
