Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 700mm 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 JSIJ40X700-40S
Generating 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site adaptability to long-stroke tasks. The external stop screw lets you trim the extend stroke by up to 40 mm, giving a usable range of 660 to 700 mm so you can fine-tune the end position without remounting hardware. The retract end remains fixed. Because the nominal 700 mm stroke is the maximum, this adjuster is ideal for dialing in exact travel limits after installation.
Built to JIS standards with an extruded hard-anodized aluminum profile barrel, the body is shorter and more compact than an equivalent ISO 15552 cylinder. It handles about 377 N of real work safely, which means you can lift roughly 32 kg vertically with a 2:1 margin. The G1/4 port feeds the 16 mm rod, and the -S suffix means a built-in magnet is ready for CMSE or DMSE sensors in the side grooves. Remember that the adjustable stop sets position only; it does not lock the load on air loss, so use an external rod lock for vertical holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-40S Is Used
Conveyor Diverter Tuning
Dial in the exact pusher extension by up to 40 mm to match varying package widths on a sorting line without swapping the cylinder.
Long-Reach Pallet Stop
Use the 700 mm travel to reach across a conveyor lane, adjusting the final stop position on-site to accommodate different pallet depths.
Extended Press Stroke
Fine-tune the 660 to 700 mm extend limit for a long-axis assembly press, ensuring precise contact without repositioning the machine.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-40S the Right Cylinder?
When sizing this actuator, the 40 mm bore offers a middle ground: step down to a 32 mm bore for lighter loads under 400 N, or move up to a 50 mm bore if you need 982 N of push at 0.5 MPa. The -40 mm adjustable window is highly useful when you need a shared spare across slightly different stroke variants or want to dial in the end position on-site. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. Because the 700 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage. The -S magnet allows drop-in CMSE or DMSE switches for position sensing.

- ✓ 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 JSIJ40X700-40S FAQ
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. This 40 mm bore model uses a G1/4 air port and a 16 mm piston rod with an M14x1.5 thread.
The nominal 700 mm stroke is the maximum travel. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 660 to 700 mm. The retract end is fixed. This mechanism only sets the end position and does not hold the load on air loss.
