Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X250-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X250-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 250mm 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 JSIJ50X250-100
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS cylinder features an on-site extend-shortening window for precise positioning. Its extruded hard-anodized aluminium profile barrel is noticeably shorter and more compact than a same-bore ISO 15552 unit, saving valuable machine space. The G1/4 port keeps air flow balanced for a 30-800 mm/s speed range.
The external adjuster lets you trim the extend stroke by up to 100 mm on-site, giving a usable range of 150-250 mm from the 250 mm nominal maximum. This allows fine end-position tuning without swapping the cylinder, handling a safe working load of about 589 N or lifting roughly 50 kg vertically. Note this non-magnet SKU cannot take a sensor; for the CMSE/DMSE switch set you need the -S variant.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X250-100 Is Used
Sorter Diverter Tuning
Dial in the 150-250 mm extend reach on-site to match varying package widths on a sorting line without changing the cylinder mount.
Press Stroke Adjustment
Shorten the extend end-position by up to 100 mm to accommodate different material thicknesses in a light-duty assembly press.
Compact Pallet Stop
Fit a space-saving JIS profile stop into a tight conveyor frame, using the adjuster to set the exact halt position for pallets.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X250-100 the Right Cylinder?
Size this 50 mm bore against its neighbours: the 40 mm gives 628 N push at 0.5 MPa, while the 63 mm jumps to 1559 N. The JSIJ mounting set includes Basic, FA, LB, TC, TCM1, and TCM2 options. Because this is a non-magnet SKU, it cannot accept a magnetic switch; order the -S version if you need CMSE/DMSE sensors. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the rod seal.
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 JSIJ50X250-100 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum is 200 kgf at 1.0 MPa. It uses a G1/4 port, a 20 mm rod, an M18x1.5 rod thread, and a 20.5 mm adjustable cushion at each end.
The 250 mm nominal stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 100 mm on-site, yielding a usable extend range of 150-250 mm. The retract end is fixed. This stop only sets the end position; it is not a load lock, so use an external rod lock or pilot-operated check valve to hold a load.
