Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 450mm 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 JSIJ40X450-75
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features an on-site extend-shortening window of 75 mm. The external adjuster lets you tune the usable extend stroke down from the 450 mm maximum to 375 mm without swapping the actuator, while the retract end remains fixed. It handles about 377 N of real work safely, which means roughly 32 kg lifted vertically with a 2:1 margin. The hard-anodized aluminum extruded barrel keeps the overall 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 30-800 mm/s with 20.5 mm adjustable air cushions at both ends. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE position sensors. Note that the adjustable stop sets the end position but does not lock the load; if air drops, the piston drifts, so fit an external rod lock or pilot-operated check valve for held loads. With a 450 mm stroke, use external guides to prevent rod bending under side loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75 Is Used
Conveyor Diverter Stroke Tuning
Fine-tune the 375 to 450 mm extend reach on-site to match varying package sizes without changing the cylinder mount.
Adjustable End Stop Pressing
Dial in the exact 40 mm bore contact position for light assembly tasks, relying on the 628 N push force at 0.5 MPa.
Compact Sortation Pusher
Leverage the shorter JIS profile body to fit tight transfer stations while pushing up to 32 kg vertical loads safely.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X450-75 the Right Cylinder?
When sizing, step down to a 32 mm bore for lighter duties (402 N push at 0.5 MPa) or up to a 50 mm bore if you need more thrust (982 N push at 0.5 MPa). The 75 mm adjuster window is ideal for sharing one spare across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. For any stroke at or above 300 mm, always support the load with external guides to avoid rod bending. This non-magnet SKU cannot host sensors; choose an -S version if you require CMSE or DMSE switches.
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 JSIJ40X450-75 FAQ
This 40 mm bore cylinder 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 16 mm piston rod with an M14x1.5 thread.
The external stop screw lets you shorten the extend stroke on-site by up to 75 mm. The usable extend range is 375 to 450 mm, with 450 mm being the maximum nominal stroke. The retract end is fixed. This mechanism only sets the end position and does not lock the load.
