Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-20S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 900mm 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 JSIJ40X900-20S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for precise on-site end-position tuning. The external adjuster lets you shorten the extend stroke by up to 20 mm, giving a usable range of 880-900 mm without swapping the actuator. It handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 margin. The hard-anodized aluminum extruded barrel keeps the total envelope shorter and more compact than a same-bore ISO 15552 unit.
This double-acting single-rod model features a G1/4 port, a 16 mm rod, and an M14x1.5 rod-end thread. Because it carries the -S suffix, a built-in piston magnet is included for CMSE/DMSE switches that mount directly into the side grooves. The 20.5 mm adjustable air cushions at both ends absorb impact, but remember the cylinder relies on live air; use an external rod lock or pilot-operated check valve if you need to hold a load securely.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-20S Is Used
Transfer Line Diverter
Fine-tune the 900 mm extend position by up to 20 mm on-site to perfectly align a diverting arm across a changing conveyor belt layout.
Vertical Package Lift
Lifts roughly 32 kg of boxed goods vertically using the 628 N push force, with the built-in magnet tracking position for reliable stacking.
Long-Reach Push Station
Pushes parts across a wide 880-900 mm gap, using the adjustable stop to dial in the exact contact point without re-mounting the cylinder.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X900-20S the Right Cylinder?
When sizing this actuator, check both directions: the 32 mm bore offers a lighter 402 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N if your payload increases. The 40 mm bore provides 879 N of push at 0.7 MPa, making it a solid mid-range choice. The -20 mm adjustable window is ideal for sharing a single spare cylinder across multiple stroke variants or fine-tuning the final extended position on-site. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 900 mm stroke is quite long, always use external guides to prevent rod bending and manage side loads.
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 JSIJ40X900-20S 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.
The nominal 900 mm stroke is the maximum length. An external stop screw lets you shorten the extend stroke by up to 20 mm on-site, yielding a usable range of 880-900 mm. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
