Airtac JSI Series Standard Cylinder JSI40X330SH
The AirTAC Airtac JSI Series Standard Cylinder JSI40X330SH is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 330mm 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 JSI40X330SH
Delivering 628 N of push force at 0.5 MPa, this double-acting 40 mm bore JIS-standard profile cylinder is purpose-built for tight machinery. Because it uses an extruded hard-anodized aluminum barrel instead of external rods, the overall envelope is noticeably shorter and more compact than a same-bore ISO 15552 unit. The internal two-way piston seal retains grease for a long, low-friction service life. Equipped here with a -S piston magnet and high-temperature -H seal option, it accepts CMSE or DMSE reed and electronic switches directly in the side grooves.
At 0.5 MPa you should plan for a safe working load of about 377 N, which equates to lifting roughly 32 kg vertically with a 2:1 safety margin. The 330 mm stroke operates at 30-800 mm/s, and the G1/4 port matches the 40 mm bore specification. Adjustable air cushions at both ends absorb end-of-stroke impact, while the M14x1.5 rod thread simplifies mounting.

Where the Airtac JSI Series Standard Cylinder JSI40X330SH Is Used
Package Diverting
Pushes light cartons off a packaging line using the 628 N push force, with the 330 mm stroke reaching across a narrow transport belt.
Vertical Part Lifting
Raises lightweight plastic totes weighing up to 32 kg on a storage retrieval unit, safely operating within the 2:1 vertical lift margin.
Component Ejection
Ejects molded parts from a small press, utilizing the hard-anodized barrel and grease-retaining seal for high-cycle durability.
Is the Airtac JSI Series Standard Cylinder JSI40X330SH the Right Cylinder?
If 628 N is excessive for your fixture, the smaller JSI32 bore offers 402 N; if you need more power, stepping up to the JSI50 provides 982 N at the same 0.5 MPa. Because this 330 mm stroke is relatively long, support the load with an external guide to prevent rod bending and premature seal wear. Remember that a standard cylinder drifts if air pressure drops or the valve is centered, so fit an external rod lock or pilot-operated check valve if you need to hold a vertical load safely. The -S magnet on this unit is ready for CMSE/DMSE sensors.
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 JSI40X330SH FAQ
The 40 mm bore has a G1/4 port. 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.
It is a JIS-standard profile cylinder that is shorter and more compact than an ISO 15552 cylinder of the same 40 mm bore. It features a hard-anodized aluminum barrel with no external rods, and this -S variant includes a magnet for CMSE/DMSE sensors.
