Airtac JSI Series Standard Cylinder JSI32X275S
The AirTAC Airtac JSI Series Standard Cylinder JSI32X275S is a genuine double acting JIS-standard air cylinder with a Ø32mm bore and 275mm 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 JSI32X275S
Delivering 402 N of push force at 0.5 MPa, this double-acting 32 mm bore cylinder is built for light automation tasks. As a JIS-standard profile unit, it occupies a shorter envelope than an ISO 15552 cylinder of the same bore, saving valuable space on compact machinery. 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.
Because this SKU includes the -S magnet, it readily accepts CMSE or DMSE electronic switches in the side grooves for position sensing. Plan for roughly 241 N of real work at 0.5 MPa, which translates to lifting about 20 kg vertically with a 2:1 safety margin. The unit features a G1/8 port, an M10x1.25 rod thread, and adjustable 20 mm air cushions at both ends to smooth out the 275 mm travel.

Where the Airtac JSI Series Standard Cylinder JSI32X275S Is Used
Small Part Ejection
Pushes lightweight plastic mouldings out of an injection press using 402 N of force at 0.5 MPa, relying on the 275 mm stroke to clear the machine platen.
Package Diverting
Actuates a routing flap on a packaging line, where the compact JIS profile keeps the conveyor frame narrow and the -S magnet confirms flap position.
Electronic Pick-and-Place
Moves delicate PCB assemblies between test stations, lifting about 20 kg vertically with a 2:1 margin while the hard-anodized barrel resists workshop wear.
Is the Airtac JSI Series Standard Cylinder JSI32X275S the Right Cylinder?
When sizing this 32 mm bore, dropping below it is impossible as it is the smallest JSI option available; stepping up to the 40 mm bore increases the 0.5 MPa push force to 628 N for heavier cycles. This -S variant is correctly configured for CMSE and DMSE sensors, whereas a plain SKU without the S suffix cannot take a switch. At 275 mm of stroke, the piston rod is extended enough that you should support the load with an external guide to prevent rod bending and premature seal wear.
Remember that standard air cushions only decelerate the piston near the stroke ends and never act as a lock. If your process requires the load to stay put upon air loss or valve centering, fit an external rod lock or a pilot-operated check valve, as the piston will drift otherwise.
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 JSI32X275S FAQ
This 32 mm bore model uses a G1/8 port and an M10x1.25 rod thread. It generates 402 N push and 345 N pull at 0.5 MPa, 563 N push and 483 N pull at 0.7 MPa, with a theoretical maximum 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. You can mount it via LB foot, FA/FB flange, CA/CB/CR clevis, TC/TCM1/TCM2 trunnion, or an I/Y/F/U rod knuckle.
