Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-50 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 JSIJ40X1000-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site versatility to long-stroke tasks. The extruded hard-anodized aluminum profile keeps the body highly compact, making it noticeably shorter than an ISO 15552 cylinder of the same bore. It connects via a G1/4 port and uses an M14x1.5 rod thread.
The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable range of 950 to 1000 mm while the retract end stays fixed. This means you can fine-tune the end position without changing the cylinder itself. In practical terms it handles about 377 N of real work, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin. Note that this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-50 Is Used
Long-Transfer Pusher
Pushes parts down a 950 mm conveyor segment, using the 50 mm adjuster to dial the exact push-off distance without remounting the actuator.
Warehouse Divert Gate
Actuates a long diverting arm on a sorting line, where the compact JIS profile saves valuable machine footprint compared to standard ISO units.
Packaging Feed Stop
Extends to halt large cartons at a wrapping station, allowing operators to tweak the 1000 mm extend endpoint by up to 50 mm for different box sizes.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X1000-50 the Right Cylinder?
When sizing this actuator, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while moving up to a 50 mm bore increases it to 982 N. The 50 mm adjustable window is ideal for sharing one spare across multiple stroke variants or dialing in exact end positions during machine commissioning. You can mount it using basic, FA, LB, TC, TCM1, or TCM2 brackets. Because this is a 1000 mm stroke, always use an external guide rail to prevent rod bending and side-load damage. Also, remember the air cushion only decelerates the piston; use an external rod lock or pilot-operated check valve if you need to hold a load vertically.
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 JSIJ40X1000-50 FAQ
This 40 mm bore actuator pushes 628 N and pulls 528 N at 0.5 MPa. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 air port and features a 20.5 mm adjustable air cushion at each end.
The nominal 1000 mm stroke is the maximum length. The external adjuster lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 950 to 1000 mm. The retract end remains fixed. This stop screw sets the end position and does not lock the load.
