Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-10S 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 JSIJ40X100-10S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic unit handles about 377 N of real work, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin. The hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder, and the G1/4 air port keeps flow balanced for the 30-800 mm/s speed range.
The -10 code means an external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable range of 90-100 mm without swapping the cylinder. Because this is an -S SKU, a built-in piston magnet works directly with CMSE/DMSE sensors in the side grooves. Note that the retract end is fixed, and the adjustable air cushions only decelerate the load; you will need an external rod lock or pilot-operated check valve to hold a load on air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-10S Is Used
End-Position Trimming
Use the 10 mm extend window to dial in the exact 90-100 mm reach for a machining fixture without machining new spacers.
Transfer Push-off
Pushes parts off a belt with 628 N of force, using the on-site adjuster to compensate for varying product widths.
Vertical Lift Stops
Lifts roughly 32 kg loads vertically, with the external stop allowing quick height tweaks when the destination changes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X100-10S the Right Cylinder?
When sizing, the 32 mm bore (402 N push at 0.5 MPa) is the lighter neighbor, while the 50 mm bore (982 N push) steps up for heavier cycles. This 40 mm model gives 528 N of pull force at 0.5 MPa, fitting neatly between them. The adjustable stroke is ideal for fine-tuning end positions on-site or sharing a single spare across multiple stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. The -S magnet enables position feedback, and for any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to 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 JSIJ40X100-10S 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 nominal 100 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable 90-100 mm range. The retract end remains fixed, and the stop screw sets the end position but does not lock the load.
