Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S is a genuine double acting, adjustable stroke 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 JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 40 mm. The nominal 1000 mm stroke remains the maximum travel, yielding a usable 960 to 1000 mm extend range, while the retract end stays fixed. It carries a G1/4 port and an M14x1.5 rod thread.
Built with an extruded hard-anodized aluminium barrel, the body is noticeably shorter and more compact than a same-bore ISO 15552 cylinder. The integrated -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for precise position detection. Factoring in a 60 percent safety margin, it handles about 377 N of real work, which translates to safely lifting roughly 32 kg vertically.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S Is Used
Long-Reach Transfer
Pushes parts down a 1000 mm lane, using the 40 mm adjuster to dial in the exact hand-off position to the next station.
Vertical Material Lift
Raises lightweight trays through a 960 to 1000 mm range, relying on the compact JIS profile to fit tight vertical elevator shafts.
Carton Positioning
Extends to push varying box sizes into a sealing head, retracting instantly while sensors confirm the adjusted end point.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S the Right Cylinder?
When sizing this actuator, the neighbouring 32 mm bore provides 402 N push at 0.5 MPa for lighter duties, whereas stepping up to the 50 mm bore yields 982 N for higher demand. The 40 mm option here strikes a balance with 879 N available at 0.7 MPa. The -40 mm adjuster is invaluable for fine-tuning the extended end position without swapping the cylinder, making it ideal for standardising spare parts across slightly different stroke variants. Mounting choices include FA, LB, TC, TCM1, and TCM2. Because the stroke is 1000 mm, always support the load with external guides to prevent rod bending and excessive side loading.
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 JSIJ32~50 Adjustable Cylinder JSIJ40X1000-40S FAQ
This 40 mm bore cylinder uses a G1/4 port. It generates 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.
An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable extend range of 960 to 1000 mm. The nominal 1000 mm stroke is the maximum travel, and the retract end remains fixed. Note that this mechanism sets the end position and does not lock the load; use an external rod lock or pilot-operated check valve to hold a load against air loss.
