Airtac JSI Series Standard Cylinder JSI40X160
The AirTAC Airtac JSI Series Standard Cylinder JSI40X160 is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 160mm stroke, G1/4 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 JSI40X160
Delivering 628 N of push force at 0.5 MPa, this double-acting 40 mm bore JIS-standard profile cylinder manages a 160 mm stroke while remaining shorter and more compact than an equivalent ISO 15552 unit. The extruded hard-anodized aluminum barrel omits external rods to resist wear, and the 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 real-world sizing, plan for about 377 N of actual work at 0.5 MPa (roughly 60 percent of the rated push), which translates to lifting about 32 kg vertically with a 2:1 safety margin. The unit features a G1/4 port and an M14x1.5 rod thread.

Where the Airtac JSI Series Standard Cylinder JSI40X160 Is Used
Package Diverter Gate
Actuates a routing flap on a packaging conveyor, using the 160 mm stroke to shift cardboard cartons between sorting lanes.
Small Part Clamp
Secures plastic housings during a ultrasonic welding cycle, applying up to 377 N of safe clamping force at 0.5 MPa.
Tool Ejector
Pushes finished aluminum die-cast parts out of a machining fixture, relying on the compact profile to fit tight cell boundaries.
Is the Airtac JSI Series Standard Cylinder JSI40X160 the Right Cylinder?
If 628 N of push is too much, the smaller JSI32 bore offers 402 N; if your fixture needs more power, stepping up to the JSI50 provides 982 N at the same 0.5 MPa. Remember that this plain cylinder will drift if air pressure drops or the valve is centered, as the adjustable 20.5 mm air cushions only decelerate the piston near stroke ends rather than locking the load. To hold a vertical position securely, add an external rod lock or a pilot-operated check valve.
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 JSI40X160 FAQ
This 40 mm bore model uses a G1/4 port. It generates 628 N push and 528 N pull at 0.5 MPa, 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet option, so CMSE or DMSE switches cannot be used. You would need the JSI40X160-S variant to enable side-groove position sensing.
