Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100 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 JSIJ50X450-100
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications needing on-site end-position tuning. The hard-anodized aluminium barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin.
The external stop screw provides a 100 mm extend-shortening window, meaning your usable forward stroke ranges from 350 mm up to the 450 mm maximum while the retract end remains fixed. This model uses a G1/4 port and a 20 mm rod with an M18x1.5 thread. Because this is a non-magnetized SKU, it cannot accept CMSE or DMSE sensors; adding the -S variant enables magnetic switching. Note that the air cushion only decelerates the piston near stroke end, so fit an external rod lock or pilot-operated check valve if you need to hold a load against gravity.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100 Is Used
Transfer Push-Off Tuning
Dial in the exact 350 to 450 mm push-off distance for varying product sizes on a packaging line using the external stop screw.
Pallet Stopper Adjustment
Fine-tune the extend endpoint on-site to accommodate different pallet depths without physically remounting the actuator.
Multi-Part Forming Stop
Shift the extend stroke within the 100 mm window to set precise material forming depths for mixed production runs.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-100 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore raises it to 1559 N. The 100 mm adjustable window is ideal for sharing a single spare cylinder across several stroke variants or fine-tuning a final end position without swapping the whole actuator. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because the 450 mm stroke creates a leverage risk, always support the rod against side-load bending with an external linear guide. Select the -S version if your control system requires position feedback.
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 JSIJ50X450-100 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. This 50 mm bore unit features a G1/4 air port.
The nominal 450 mm stroke is the maximum extend length. The external adjuster lets you shorten the forward stroke by up to 100 mm on-site, giving a usable extend range of 350 to 450 mm. The retract end position is fixed, and the adjuster sets the end stop rather than locking the load.
