Airtac JSI Series Standard Cylinder JSI32X225S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X225S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 225mm 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 JSI32X225S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore JIS-standard profile cylinder is built for tight machinery envelopes. It is purposefully shorter and more compact than an ISO 15552 cylinder of the same bore, saving valuable space without sacrificing performance. The 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 across its 225 mm stroke.
Because the -S suffix equips the piston with a magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing. 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 features a G1/8 port, an M10x1.25 rod thread, and adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X225S Is Used
Small Part Ejection
Uses the 345 N pull force at 0.5 MPa to eject molded plastic components from a 225 mm deep cavity on an injection molding machine.
Pallet Diverter
Pushes lightweight product cartons onto a secondary packaging line, relying on the compact JIS profile to fit inside narrow conveyor frames.
Clamp Actuation
Actuates a small pneumatic clamp on an electronics assembly fixture, using the built-in magnet to confirm the 225 mm extension before a robotic arm enters the cell.
Is the Airtac JSI Series Standard Cylinder JSI32X225S the Right Cylinder?
When sizing this 32 mm bore unit, stepping up to the 40 mm bore raises the 0.5 MPa push force to 628 N for heavier loads, while 32 mm is the smallest available JSI option. The 225 mm stroke is well within the 1000 mm maximum standard stroke for this bore, but at this length you should support the load with an external guide to prevent rod bending and premature seal wear. The included -S magnet pairs perfectly with CMSE or DMSE sensors for mid-stroke detection. Remember that a standard cylinder drifts if air pressure is lost or the valve is centered; the end cushions only decelerate the piston near stroke end and will not hold a load, so specify an external rod lock or pilot-operated check valve if position holding is required.
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 JSI32X225S FAQ
This 32 mm bore cylinder generates 402 N push and 345 N pull at 0.5 MPa, increasing to 563 N push and 483 N pull at 0.7 MPa. 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.
The JSI is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same bore, making it ideal for space-constrained machines. It shares common mounting styles like LB foot, FA/FB flange, and TC trunnion, but it is not dimensionally interchangeable with the ISO standard.
