Airtac JSI Series Standard Cylinder JSI32X250S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X250S 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 JSI32X250S
Delivering 402 N of push force at 0.5 MPa, the AirTAC JSI32X250S is a double-acting JIS-standard profile cylinder built for tight machinery. Its extruded hard-anodized aluminum barrel omits external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 32 mm bore. A heterogeneous two-way piston seal retains grease for long, low-friction life.
The -S suffix equips this unit with a piston magnet for CMSE or DMSE sensors that drop directly into the side grooves. Plan for roughly 241 N of actual work at 0.5 MPa, which translates to lifting about 20 kg vertically with a 2:1 safety margin. It features a G1/8 port, an M10x1.25 rod thread, and adjustable 20 mm air cushions at both ends to decelerate the piston smoothly.

Where the Airtac JSI Series Standard Cylinder JSI32X250S Is Used
Small Parts Ejection
Ejects lightweight molded plastic parts from a 250 mm deep cavity using 402 N of push force at 0.5 MPa.
Vertical Tray Lifting
Raises stacked packaging trays 250 mm, safely handling roughly 20 kg loads with a 2:1 safety margin.
Pallet Diverter
Pushes small cardboard cartons sideways off a conveyor belt during a 250 mm transfer stroke.
Is the Airtac JSI Series Standard Cylinder JSI32X250S the Right Cylinder?
For sizing context, the 32 mm bore is the smallest in the JSI series; if your task needs more force, the next size up is the 40 mm bore yielding 628 N push at 0.5 MPa. Because this 250 mm stroke exceeds 200 mm, ensure your mounting handles side loads to prevent rod bending by using a guide rail or external bearing. Remember that the air cushions only decelerate the piston near stroke end and do not function as a brake; if you need to hold a load vertically during air loss, add an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or an I/Y/F/U rod knuckle.
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 JSI32X250S FAQ
At 0.5 MPa it provides 402 N push and 345 N pull. At 0.7 MPa it yields 563 N push and 483 N pull, with a theoretical maximum of 82 kgf at 1.0 MPa. The air port size is G1/8.
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 on tight machines. The -S magnet allows CMSE or DMSE switches to be fitted directly into the side grooves.
