Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 450mm 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 JSIJ40X450-100S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore model shrinks the footprint compared to a same-size ISO 15552 unit. The hard-anodized aluminum profile barrel keeps the assembly light, and the G1/4 port matches the bore standard.
The -100 code means an external adjuster can shorten the extend stroke on-site by up to 100 mm, dropping the usable extension from the 450 mm maximum down to 350 mm without swapping the cylinder. Factoring in a safety margin, it handles about 377 N of real work, which is roughly 32 kg lifted vertically. The retract end remains fixed, and the built-in -S magnet accepts CMSE/DMSE sensors in the side grooves.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100S Is Used
Stroke Tuning for Diverter Gates
Dial in the exact extend reach from 350 to 450 mm on-site to perfectly align a package diverter without machining new hard stops.
Adjustable Transfer Pusher
Shorten the extension window by up to 100 mm to accommodate varying product lengths on a single transfer line.
Spare Consolidation
Keep one 450 mm cylinder in stock and adjust the stop screw to cover shorter, non-standard machine requirements.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-100S the Right Cylinder?
If 628 N of push at 0.5 MPa is too light, stepping up to the 50 mm bore yields 982 N; if that is excessive, the 32 mm bore provides 402 N. The adjustable window shines when you need to fine-tune an end position on the floor or standardize one spare across several stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 450 mm stroke invites rod bending, always use an external guide to absorb side loads.
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 JSIJ40X450-100S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum is 128 kgf at 1.0 MPa. The air port is G1/4.
The 450 mm nominal stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on-site, giving a usable extension range of 350 to 450 mm. The retract end is fixed, and this mechanism only sets position, it does not lock the load.
