Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-50 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 JSIJ40X160-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to compact automation setups. Its hard-anodized extruded aluminium barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/4 air port feeds the double-acting single-rod piston, which travels at 30-800 mm/s.
The external -50 adjuster lets you shorten the extend stroke from the 160 mm maximum down to 110 mm without swapping the cylinder, while the retract end remains fixed. In practice it handles a safe working load of about 377 N, which means you can vertically lift roughly 32 kg with a 2:1 safety margin. Note that this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-50 Is Used
Clamp Stroke Trimming
Dial in the exact clamping reach on a machining fixture by backing the extend stroke down from 160 mm using the 50 mm external adjuster.
Transfer Pusher Tuning
Fine-tune the push-off distance at a conveyor sorting station without machining new hard stops, shortening the extend action up to 50 mm.
Carton Flap Folding
Adjust the folding finger extension on the fly for different box sizes, relying on the 628 N push force to crease heavy corrugated board.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-50 the Right Cylinder?
When sizing this 40 mm bore, the neighbouring 32 mm bore offers 402 N push at 0.5 MPa for lighter duties, while stepping up to a 50 mm bore yields 982 N for heavier cycles. The adjustable -50 mm window is ideal for sharing one spare cylinder across several stroke variants or fine-tuning the end position during machine commissioning. You can mount it via Basic, FA, LB, TC, TCM1, or TCM2 brackets. Because this non-S SKU has no magnet, position sensing is impossible without switching to the -S version. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ40X160-50 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. This 40 mm bore cylinder uses a G1/4 air port and features a 20.5 mm adjustable air cushion at each end.
The 160 mm nominal stroke is the maximum extend length. The external -50 adjuster is a stop screw that lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 110 to 160 mm. The retract end is fixed. This mechanism 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 against air loss.
