Airtac JSI Series Standard Cylinder JSI40X160S
The AirTAC Airtac JSI Series Standard Cylinder JSI40X160S 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 JSI40X160S
Delivering 628 N of push force at 0.5 MPa, the AirTAC JSI40X160S is a double-acting JIS-standard profile cylinder engineered for tight machinery layouts. Its extruded, hard-anodized aluminum barrel omits external rods entirely, making the unit significantly shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore. The internal two-way piston seal actively retains grease, ensuring low-friction operation over a long service life.
Equipped with a built-in magnet (-S), this model accepts CMSE or DMSE reed and electronic switches that drop directly into the side sensor grooves. Buyers should plan for roughly 377 N of actual work at 0.5 MPa, which translates to lifting about 32 kg vertically with a 2:1 safety margin. The unit features a G1/4 port, an M14x1.5 rod thread, and adjustable air cushions at both ends to decelerate the piston smoothly over its 160 mm stroke.

Where the Airtac JSI Series Standard Cylinder JSI40X160S Is Used
Package Diverting
Pushes lightweight cardboard cartons at 30-800 mm/s onto secondary sorting lines using the 628 N push rating.
Small Part Ejection
Ejects molded plastic components from a press, utilizing the 160 mm stroke and grease-retaining seal for millions of cycles.
Clamp Actuation
Secures aluminum extrusions during a sawing operation, safely clamping parts weighing up to 32 kg vertically.
Is the Airtac JSI Series Standard Cylinder JSI40X160S the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm version reduces the push force to 402 N at 0.5 MPa, while stepping up to a 50 mm bore increases it to 982 N. Because this 160 mm stroke is moderate, side-load risks are minimal, but always ensure the load is guided to prevent rod bending. The included -S magnet pairs perfectly with CMSE or DMSE sensors for position detection. Remember that the adjustable cushions only decelerate the piston near the stroke ends; they do not act as a brake. If the application requires the load to remain held during air loss or valve centering, you must add an external rod lock or a pilot-operated check valve to prevent drift.
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 JSI40X160S FAQ
This 40 mm bore cylinder features a G1/4 port and an M14x1.5 rod thread. The thrust outputs are 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.
The JSI series follows JIS standards and utilizes a no-tie-rod extruded profile barrel, making it shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore. This space-saving design is ideal for tight machine envelopes without sacrificing the 160 mm stroke.
