Airtac JSI Series Standard Cylinder JSI40X1000
The AirTAC Airtac JSI Series Standard Cylinder JSI40X1000 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 JSI40X1000
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 equivalent ISO 15552 unit of the same 40 mm bore. The extruded hard-anodized aluminum barrel omits external rods to resist wear, while the two-way piston seal retains grease for a long, low-friction service life across its 1000 mm travel.
Because this specific SKU lacks the -S magnet, it cannot accept CMSE or DMSE position switches in the side grooves. For real-world sizing, 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 and a 16 mm rod with an M14x1.5 thread.

Where the Airtac JSI Series Standard Cylinder JSI40X1000 Is Used
Long-Reach Diversion
Pushes packages across a 1-meter wide sorting conveyor using the 628 N push force, guided externally to prevent rod bending over the extended travel.
Palletizer Feed
Stages cardboard cartons at the infeed of a palletizing cell, where the compact JIS profile saves footprint compared to standard ISO 15552 units.
Sample Extraction
Extracts testing racks from deep within industrial ovens, utilizing the 32 kg vertical lift capacity to lower samples safely with a 2:1 margin.
Is the Airtac JSI Series Standard Cylinder JSI40X1000 the Right Cylinder?
When sizing this 40 mm bore, dropping down to a 32 mm version reduces the 0.5 MPa push force to 402 N, whereas stepping up to a 50 mm bore increases it to 982 N. To hold a load vertically or prevent drift if air pressure is lost, you must add an external rod lock or a pilot-operated check valve, as the adjustable 20.5 mm air cushions only decelerate the piston near stroke end and act purely as end-of-stroke buffers.
Spanning a full 1000 mm, this long stroke demands careful attention to side loads. To prevent rod bending and premature seal wear, always guide the load externally and avoid applying lateral forces to the piston rod. Furthermore, since this configuration has no magnet, select the -S variant if your application requires end-of-stroke detection.
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 JSI40X1000 FAQ
This 40 mm bore cylinder features a G1/4 port and generates 628 N push / 528 N pull at 0.5 MPa, 879 N push / 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. It operates at speeds between 30 and 800 mm/s.
No, this specific SKU does not include a magnet. To use CMSE or DMSE switches in the side sensor grooves, you must purchase the -S variant of this JIS-standard profile cylinder.
