Airtac JSI Series Standard Cylinder JSI40X360S
The AirTAC Airtac JSI Series Standard Cylinder JSI40X360S is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 360mm 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 JSI40X360S
Delivering 628 N of push force at 0.5 MPa, the AirTAC JSI40X360S is a double-acting JIS-standard profile cylinder built for tight machinery layouts. Its extruded hard-anodized aluminum barrel omits external rods entirely, making the body shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore. The internal two-way piston seal retains grease for low-friction service over long cycles. Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for position sensing. The G1/4 air port and M14x1.5 rod thread handle the 360 mm travel, while adjustable air cushions at both ends soften the impact at stroke extremes.
For real-world sizing, plan for about 377 N of actual work at 0.5 MPa, which is roughly 60 percent of the theoretical rating. That translates to lifting about 32 kg vertically with a 2:1 safety margin, helping you match the cylinder to actual part weights without over-specifying the bore.

Where the Airtac JSI Series Standard Cylinder JSI40X360S Is Used
Package Diverting
Extends a 360 mm stroke to push cartons off a main conveyor belt into a sorting lane using a reliable 628 N push force at 0.5 MPa.
Vertical Parts Lift
Raises lightweight industrial bins weighing up to 32 kg between elevator tiers, relying on the built-in -S magnet to trigger floor-level sensors.
Film Roll Feed
Advances a packaging film roll carriage through a 360 mm travel path, utilizing the adjustable end cushions to prevent harsh stopping at high cycle speeds.
Is the Airtac JSI Series Standard Cylinder JSI40X360S the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm JSI drops the 0.5 MPa push force to 402 N, while moving up to a 50 mm bore increases it to 982 N. This JSI40X360S variant includes the -S magnet for side-groove sensors. Keep in mind that a standard double-acting cylinder will drift if air pressure is lost or the valve is centered; the adjustable cushion only decelerates the piston near the end of travel and does not function as a locking brake. To suspend a load safely, add an external rod lock or a pilot-operated check valve.
Because the 360 mm stroke is relatively long, avoid applying heavy side loads directly to the extended rod. Bending moments can cause premature wear, so use an external guide rail or linear bearing to support the driven component and keep the piston rod aligned.
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 JSI40X360S FAQ
The 40 mm bore provides 628 N push and 528 N pull at 0.5 MPa, or 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. The air port size is G1/4.
It is a JIS-standard profile cylinder featuring an extruded aluminum barrel without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same bore. It is not dimensionally interchangeable with ISO 15552.
