Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100S 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 JSIJ40X160-100S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to lighter automation tasks. An external adjuster lets you shorten the forward stroke by up to 100 mm, giving a usable 60-160 mm range while the retract end stays fixed. You can fine-tune the end position without physically swapping the cylinder, which is ideal for sharing a spare across stroke variants. The hard-anodized aluminum extruded barrel keeps the total build shorter than a same-bore ISO 15552 unit, and the G1/4 port matches the bore standard.
With a built-in piston magnet, this -S SKU accepts CMSE/DMSE sensors that drop directly into the side grooves for precise position detection. It handles about 377 N of safe working load, which translates to lifting roughly 32 kg vertically with a 2:1 margin. Adjustable air cushions of 20.5 mm at each end absorb kinetic energy near the stroke limits, but remember the cushion only decelerates; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100S Is Used
Clamp Stroke Tuning
Dial in the exact 60 to 160 mm forward clamping distance on-site without machining spacers or changing the cylinder body.
Variable Transfer Stops
Adjust the extend stop position to accommodate different product lengths on a single conveyor line using the external screw.
Shared Spare Inventory
Keep one cylinder as a universal replacement, shortening the 160 mm stroke as needed to fit shorter 60 mm or 100 mm machines.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-100S the Right Cylinder?
When sizing this 40 mm bore, step down to a 32 mm bore for sub-400 N tasks, or step up to a 50 mm bore if you need 982 N of push at 0.5 MPa. The 100 mm adjustable window is especially useful when you need to dial in a precise end position on-site or want a single spare to cover multiple shorter stroke machines. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet supports CMSE/DMSE switches for end-of-stroke confirmation. Because the 160 mm stroke exceeds 300 mm only marginally, side loading remains low, but you should still guide the load to prevent rod bending on any extension over 300 mm.
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 JSIJ40X160-100S 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. The air port is G1/4.
The external adjuster lets you shorten the extend stroke by up to 100 mm on-site. The nominal 160 mm stroke is the maximum, giving a usable extend range of 60 to 160 mm, while the retract end remains fixed. This sets the end position and is not a load lock.
