Airtac JSI Series Standard Cylinder JSI40X530S
The AirTAC Airtac JSI Series Standard Cylinder JSI40X530S is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 530mm 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 JSI40X530S
Delivering 628 N of push force at 0.5 MPa, this double-acting 40 mm bore unit is built around a JIS-standard extruded hard-anodized aluminum profile that is noticeably shorter than an equivalent ISO 15552 cylinder. The absence of external rods keeps the body clean and resistant to wear, while the heterogeneous two-way piston seal retains grease for a long, low-friction service life. A built-in magnet (-S) equips it for CMSE or DMSE position switches that drop directly into the side sensor grooves.
In practical terms, you can plan for about 377 N of real work at 0.5 MPa, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin. The G1/4 port feeds the 16 mm rod, and because the 530 mm stroke is quite long for this bore, you should support the load with an external guide to prevent rod bending and premature seal wear.

Where the Airtac JSI Series Standard Cylinder JSI40X530S Is Used
Carton Push-off Diverter
Uses the 530 mm travel to push medium-weight cardboard cartons from a main packaging belt onto a secondary routing lane.
Vertical Parts Elevator
Lifts tote bins weighing up to 32 kg between floor levels, relying on the 628 N thrust at 0.5 MPa to drive the platform upward.
Long-Stroke Gate Actuator
Opens and closes a 500 mm access door on an automated assembly cell, with the hard-anodized barrel shrugging off shop-floor debris.
Is the Airtac JSI Series Standard Cylinder JSI40X530S the Right Cylinder?
If 628 N of push at 0.5 MPa is too much, the smaller JSI32 drops the output to 402 N; stepping up to the JSI50 raises it to 982 N. For this 530 mm stroke, external load guiding is essential to counter side-load forces and protect the 16 mm rod from bending. Because this SKU includes the -S magnet, you can fit CMSE or DMSE sensors for end-of-stroke detection.
Remember that the adjustable air cushions at both ends only decelerate the piston near the stroke limits; they do not act as a brake. If the machine loses air or the valve is centered, the load will drift, so fit an external rod lock or a pilot-operated check valve when you need to hold a vertical position.
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 JSI40X530S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull; at 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. The air port size is G1/4, the rod is 16 mm, and the rod-end thread is M14x1.5.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore, saving valuable machine space. The -S suffix means it has a built-in magnet, allowing CMSE or DMSE reed and electronic switches to be installed directly into the side grooves.
