Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-75S 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 JSIJ40X1000-75S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder uses an external adjuster to shorten the extend stroke on site by up to 75 mm. The nominal 1000 mm travel remains the maximum, yielding a usable extend range of 925 to 1000 mm, while the retract end stays fixed. It handles about 377 N of real work safely, which means lifting roughly 32 kg vertically with a 2:1 margin. The hard-anodized aluminum barrel omits tie rods entirely, making the body shorter and more compact than a same-bore ISO 15552 unit.
Air connects via a G1/4 port, driving the 16 mm rod at 30 to 800 mm/s with 20.5 mm adjustable air cushions at both ends. Because this SKU carries the -S suffix, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves. The external stop screw sets the end position but does not lock the load; without live air the piston drifts, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended weight.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-75S Is Used
Long-Transfer Pushing
Pushes pallets down a 1000 mm conveyor and dials back the extend stop by 75 mm to match varying pallet depths without changing the cylinder.
Vertical Material Lift
Lifts 32 kg loads vertically using the 628 N push force, relying on the -S magnet switches to confirm the exact raised position.
Adjustable End-Stop Forming
Acts on a press line where the 1000 mm extend stroke gets fine-tuned on site by up to 75 mm to set precise material contact points.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-75S the Right Cylinder?
Size this 40 mm bore against the 32 mm option when you need more push than 402 N at 0.5 MPa, or step up to the 50 mm bore for 982 N if the load grows. The -75 mm adjustable window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position without physically swapping the cylinder. Mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 1000 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage.

- ✓ 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 JSIJ40X1000-75S FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum is 128 kgf at 1.0 MPa. The air port is G1/4.
An external stop screw lets you shorten the extend stroke on site by up to 75 mm. The nominal 1000 mm stroke is the maximum, giving a usable extend range of 925 to 1000 mm, while the retract end remains fixed.
