Airtac JSI Series Standard Cylinder JSI32X270TC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X270TC is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 270mm 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 JSI32X270TC
Generating 402 N of push force at 0.5 MPa, this double-acting 32 mm bore unit carries a 270 mm stroke in a JIS-standard profile body that is physically shorter than an equivalent ISO 15552 cylinder. The extruded hard-anodized aluminum barrel omits external rods entirely, resisting wear while the internal two-way piston seal retains grease for a long, low-friction service life. Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches.
For practical sizing, plan for about 241 N of real work at 0.5 MPa, which translates to lifting roughly 20 kg vertically with a 2:1 safety margin. The unit breathes through G1/8 ports, runs at 30-800 mm/s, and relies on a 20 mm adjustable air cushion at each end to decelerate the 12 mm chrome-plated rod smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X270TC Is Used
Small Part Ejection
Pushes light plastic or stamped metal parts out of a 32 mm bore fixture with 402 N of force at 0.5 MPa.
Diverter Gate Actuation
Moves a lightweight routing flap along a 270 mm stroke to redirect small packages on a packaging line.
Clamp Mechanism
Secures delicate electronic housings during an assembly process, lifting roughly 20 kg vertically with a 2:1 margin.
Is the Airtac JSI Series Standard Cylinder JSI32X270TC the Right Cylinder?
When sizing this 32 mm bore, stepping down is not an option as it is the smallest JSI available, but moving up to a 40 mm bore raises the push force to 628 N at 0.5 MPa if your 270 mm stroke needs more authority. This SKU is configured for TC trunnion mounting, which accommodates pivoting loads, and because it lacks the -S suffix, magnetic sensing is not supported. Since the 270 mm stroke is substantial for a 32 mm bore, ensure external guide rails carry the payload to prevent rod bending under side loads. Note that standard air cushions only decelerate the piston near stroke end; they do not hold the load if air pressure drops, so fit an external rod lock or pilot-operated check valve if you need to prevent drift.
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 JSI32X270TC FAQ
This 32 mm bore model features a G1/8 port and generates 402 N push / 345 N pull at 0.5 MPa, 563 N push / 483 N pull at 0.7 MPa, and a theoretical maximum of 82 kgf at 1.0 MPa.
It uses a JIS-standard profile design that is shorter and more compact than an ISO 15552 cylinder of the same bore. The air cushion only decelerates the piston near stroke end; it does not function as a lock, so the rod will drift if air is lost unless you add an external rod lock.
