Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X160-30S
Generating 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder delivers an on-site extend-stroke range of 130 to 160 mm. An external stop screw lets you trim the forward travel by up to 30 mm without swapping the actuator, while the retract end remains fixed. The hard-anodized aluminium extruded barrel keeps the total build shorter than a same-bore ISO 15552 unit, and the G1/4 port manages airflow for speeds of 30-800 mm/s.
The -S suffix adds a piston magnet for CMSE/DMSE switches that clip directly into the side grooves. Factoring a 60% safety margin, the 628 N output translates to a safe working load of about 377 N, or roughly 32 kg lifted vertically. Note that the adjustable air cushions only decelerate the piston near the end caps; for locked load holding on air loss, fit an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-30S Is Used
Adjustable Forming Stop
Dial in the exact 130 to 160 mm material push-off distance on a press line using the external stop screw, accommodating different blank widths without changing cylinders.
Transfer Lane Diverter
Fine-tune the actuator reach on a sorting conveyor to deflect varying package sizes precisely, relying on the compact JIS profile to fit tight transfer gaps.
Pallet Positioning Gate
Set precise physical stops for pallet entry gates, using the on-site adjustability to alter the final extended position as pallet configurations change.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-30S the Right Cylinder?
Size this 40 mm bore against its neighbours: a 32 mm bore yields 402 N push at 0.5 MPa for lighter duties, whereas a 50 mm bore steps up to 982 N if your payload exceeds the 377 N safe working load. The 30 mm adjuster window is invaluable when you need to fine-tune end positions on-site or standardise one spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The integrated magnet supports CMSE/DMSE sensors, and because the 160 mm stroke exceeds 300 mm, always guide the payload 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 JSIJ40X160-30S FAQ
This 40 mm bore cylinder uses a G1/4 port and a 16 mm rod. It generates 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum output of 128 kgf at 1.0 MPa.
The nominal 160 mm stroke is the maximum forward travel. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 130 to 160 mm. The retract position stays fixed, and this stop mechanism does not lock the load.
