Airtac JSI Series Standard Cylinder JSI40X1000STC
The AirTAC Airtac JSI Series Standard Cylinder JSI40X1000STC is a genuine double acting JIS-standard air cylinder with a Ø40mm bore and 1000mm 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 JSI40X1000STC
Delivering 628 N of push force at 0.5 MPa, this double-acting JIS-standard profile cylinder saves valuable machine space by being noticeably shorter than an ISO 15552 cylinder of the same 40 mm bore. The extruded hard-anodized aluminum barrel features no external rods to resist wear, while the two-way piston seal retains grease for long, low-friction life. 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.
Plan for about 377 N of real work at 0.5 MPa, which safely lifts roughly 32 kg vertically with a 2:1 margin. The unit connects via a G1/4 port, uses an M14x1.5 rod thread, and integrates a TC trunnion mount for pivoting articulation. The 20.5 mm adjustable air cushions at both ends absorb end-of-stroke impact, and the piston operates smoothly across a 30-800 mm/s speed range.

Where the Airtac JSI Series Standard Cylinder JSI40X1000STC Is Used
Long-Reach Diverters
Pushes packages across a wide sorting conveyor over the full 1000 mm travel, utilizing the 628 N push force to handle heavy cartons reliably.
High-Bay Extraction
Extracts totes from deep shelving racks in automated storage systems where the compact JIS profile frees up critical aisle clearance.
Material Transfer Arms
Actuates long-axis transfer arms on assembly lines, using the TC trunnion mount to accommodate pivoting motion during the 1000 mm extension.
Is the Airtac JSI Series Standard Cylinder JSI40X1000STC the Right Cylinder?
When sizing this 40 mm bore, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore raises it to 982 N. The TC trunnion mount provides a pivoting centerline that handles angular misalignment, but because this is a 1000 mm stroke, you must use external guides to prevent rod bending and absorb side loads. Remember that a standard cylinder drifts when air is lost or the valve is centered; the cushions only decelerate the piston near stroke end. For a suspended load, install 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 JSI40X1000STC FAQ
This 40 mm bore cylinder features a G1/4 port and an M14x1.5 rod thread. The thrust output is 628 N push and 528 N pull at 0.5 MPa, increasing to 879 N push and 739 N pull at 0.7 MPa. 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 bore, saving space. The built-in -S magnet allows CMSE/DMSE switches to slot into the side grooves, and the TC trunnion mount supports pivoting installations.
