Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 225mm 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 JSIJ50X225-50S
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder cuts its overall length below a same-size ISO 15552 unit. The hard-anodized aluminium barrel keeps the build light, while the integrated -S magnet allows CMSE or DMSE switches to drop directly into the side grooves for precise position detection.
A 50 mm external stop screw window lets you trim the extend stroke from 225 mm down to 175 mm right at the machine, meaning a single spare can cover several stroke variants. The retract end remains fixed, and the G1/4 port feeds the 30-800 mm/s speed range. For practical sizing, expect a safe working load around 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50S Is Used
End-Stop Trimming
Dial in the exact 175-225 mm extend position on a machining fixture without machining new hard stops or changing the cylinder.
Transfer Pusher
Pushes parts onto a conveyor with 982 N of force, using the adjuster to tune the push distance for varying product widths.
Vertical Lift
Lifts a 50 kg payload in a storage gantry using a 2:1 safety margin, relying on the -S magnet to confirm the raised position.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X225-50S the Right Cylinder?
This 50 mm bore sits between the 40 mm (628 N push @0.5 MPa) and 63 mm (1559 N) options, giving you a clear upgrade path if 825 N of pull force falls short. The adjustable stroke shines when you need to fine-tune an end position without swapping the cylinder, or when consolidating spare parts across slightly different stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 225 mm, always guide the load to prevent rod side-loading. Remember that the stop screw sets the end position only; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.
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 JSIJ50X225-50S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa the forces are 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa.
The nominal 225 mm stroke is the maximum. The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 175-225 mm. The retract end is fixed.
