Airtac JSI Series Standard Cylinder JSI32X250TC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X250TC is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 250mm stroke, G1/8 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 JSI Series Standard Cylinder JSI32X250TC
Generating 402 N of push force at 0.5 MPa, the AirTAC JSI32X250TC brings JIS-standard compactness to tight machinery. Because it uses an extruded hard-anodized aluminum profile barrel, it is noticeably shorter than an ISO 15552 cylinder of the same 32 mm bore, saving valuable space without losing strength. The two-way piston seal retains grease for a long, low-friction service life.
With a 250 mm stroke and a G1/8 port, this double-acting unit is built for TC trunnion mounting. Plan for about 241 N of real work at 0.5 MPa, which means it lifts about 20 kg vertically with a 2:1 safety margin. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE position sensors; choose the -S variant if you need drop-in side-groove switches.

Where the Airtac JSI Series Standard Cylinder JSI32X250TC Is Used
Small Parts Ejection
Deploys a 250 mm stroke to push lightweight molded plastic parts out of an injection molding die using 402 N of push force at 0.5 MPa.
Packaging Diverter
Swings a lightweight aluminum deflector gate on a packaging line via TC trunnion mounting to sort small cartons at speeds up to 800 mm/s.
Component Clamping
Secures small electronic housings during an ultrasonic welding process, applying a safe working load of roughly 241 N without crushing the part.
Is the Airtac JSI Series Standard Cylinder JSI32X250TC the Right Cylinder?
When sizing this 32 mm bore, the JSI32X250TC sits at the smallest end of the JSI range, so if you need more thrust the next step up is the 40 mm bore delivering 628 N push at 0.5 MPa. Because this is a plain cylinder without a rod lock, the piston will drift if air is lost or the valve is centered, so add a pilot-operated check valve for vertical loads. The adjustable 20 mm air cushions only decelerate the piston near the end of travel. Since the 250 mm stroke is over 300 mm, ensure external guide rails are used to prevent rod bending under 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 JSI Series Standard Cylinder JSI32X250TC FAQ
This 32 mm bore cylinder features a G1/8 port and generates a push of 402 N and pull of 345 N at 0.5 MPa. At 0.7 MPa it yields 563 N push and 483 N pull, with a theoretical maximum force of 82 kgf at 1.0 MPa.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore. It does not hold its load if air is lost, as the cushions only decelerate the piston near stroke end; use an external rod lock for suspended loads.
