Airtac JSI Series Standard Cylinder JSI32X50STC
The AirTAC Airtac JSI Series Standard Cylinder JSI32X50STC is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 50mm 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 JSI32X50STC
Delivering 402 N of push force at 0.5 MPa, the AirTAC JSI32X50STC is a double-acting 32 mm bore JIS-standard profile cylinder that saves valuable machine space by being noticeably shorter than a same-bore ISO 15552 unit. Its extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life. The integrated -S piston magnet allows CMSE or DMSE electronic switches to drop directly into the side grooves for position sensing.
Because air pressure fluctuates, plan for about 241 N of real work at 0.5 MPa, which safely lifts roughly 20 kg vertically with a 2:1 margin. This 50 mm stroke unit uses a G1/8 port, a 12 mm carbon steel rod with an M10x1.25 thread, and adjustable 20 mm air cushions at both ends to decelerate the piston smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X50STC Is Used
Small Part Ejection
Ideal for pushing lightweight plastic or electronic components out of an injection mold with a fast 50 mm stroke and 241 N of safe working force.
Pick-and-Place Grippers
Provides the extend and retract motion for small pneumatic grippers handling 20 kg vertical loads in assembly cells.
Diverting Mechanisms
Actuates short-stroke diverter arms on packaging conveyors where the compact JIS profile fits into tight transfer gaps.
Is the Airtac JSI Series Standard Cylinder JSI32X50STC the Right Cylinder?
As the smallest bore in the JSI range, there is no smaller option if 402 N at 0.5 MPa is insufficient; you would step up to the 40 mm bore, which provides 628 N of push force. If your payload is lighter, this 32 mm bore is the optimal minimum. The TC trunnion mount provides a pivoting centerline interface ideal for articulating mechanisms. Remember that a standard cylinder drifts when air is lost or a valve is centered, as the air cushion only decelerates the piston near stroke end rather than locking it; use an external rod lock or pilot-operated check valve if you must hold a load vertically.
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 JSI32X50STC FAQ
At 0.5 MPa it provides 402 N push and 345 N pull; at 0.7 MPa it provides 563 N push and 483 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a G1/8 air port and operates at speeds between 30 and 800 mm/s.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore, saving space without losing force. The -S suffix means it includes a piston magnet for CMSE/DMSE sensors.
