Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 100mm 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 JSIJ40X100-50S
Generating 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend flexibility to tight machinery. The hard-anodized aluminum barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. It feeds through a G1/4 port and carries a -S magnet for CMSE/DMSE sensors.
The -50 code means an external adjuster can shorten the extend stroke by up to 50 mm on-site, dropping the usable forward travel from the 100 mm maximum down to 50 mm without swapping the cylinder. This fine-tunes the end position perfectly. In practice it handles about 377 N of real work, which means lifting roughly 32 kg vertically with a 2:1 safety margin. The retract end remains fixed, and the adjustable air cushions only decelerate the load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-50S Is Used
End-Position Trimming
Dial in the exact extend stop on a clamping fixture by shortening the 100 mm stroke up to 50 mm on-site without changing the hardware.
Sensor-Ready Sorting
Use the built-in magnet with CMSE/DMSE switches to confirm part ejection positions in a compact 40 mm bore assembly cell.
Short-Stroke Diverting
Adjust the pusher length on the fly for different package widths on a conveyor line, relying on the 628 N push force at 0.5 MPa.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-50S 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 the 50 mm bore steps up to 982 N if you need more muscle. The adjustable stroke shines when you need to dial in a precise end position on-site or want a single shared spare across multiple stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S suffix means a magnet is built in for CMSE/DMSE switches. For any stroke at or over 300 mm, always guide the load to prevent side-load damage.
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 JSIJ40X100-50S FAQ
This 40 mm bore cylinder pushes 628 N and pulls 528 N at 0.5 MPa. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 air port and features a 16 mm rod with an M14x1.5 thread.
The 100 mm nominal stroke is the maximum travel. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable forward range of 50 to 100 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.
