Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X450-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tasks that need exact end-position tuning. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
A external stop screw provides a 10 mm on-site extend-shortening window, letting you dial in the usable stroke from 440 to 450 mm without swapping the cylinder. The retract end remains fixed. Air connects via a G1/4 port, and adjustable air cushions of 20.5 mm decelerate the piston at both ends. Note this SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10 Is Used
Conveyor Diverter Stop
Dial in the 10 mm extend window to position a divert gate exactly at the package edge without re-mounting the actuator.
Pallet Height Compensation
Adjust the extend end-position on the fly to accommodate varying pallet stack heights while using the fixed retract as a home reference.
Carton Sealing Press
Fine-tune the 440 to 450 mm stroke downward to apply precise contact pressure on different carton thicknesses without changing cylinders.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-10 the Right Cylinder?
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa for lighter duties, while the 63 mm bore jumps to 1559 N if you need more force. The 10 mm adjuster is ideal for sharing a spare across stroke variants or fine-tuning a final stop on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is a 450 mm stroke, always use an external guide to prevent rod bending and side loads. For position feedback, select the -S variant instead.
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 JSIJ50X450-10 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. This 50 mm bore unit uses a G1/4 air port and features a 20 mm rod with an M18x1.5 thread.
An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable range of 440 to 450 mm. The nominal 450 mm is the maximum. This mechanism only sets the end position; it is not a lock. The cylinder will drift on air loss, so use an external rod lock or pilot-operated check valve for held loads.
