Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-50 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 200mm 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 JSIJ50X200-50
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tight machinery where every millimetre counts. Its extruded hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod mechanism that delivers 825 N of pull on the return stroke.
The -50 suffix denotes an external stop screw that lets you shorten the extend stroke on-site by up to 50 mm, dropping the usable forward travel from the 200 mm maximum down to 150 mm without swapping the cylinder. This on-site adjuster sets the end position mechanically and is not a load lock. Factoring in a 60 percent safety margin, the cylinder safely handles about 589 N of real work, which translates to lifting roughly 50 kg vertically. Because this SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-50 Is Used
Machine Tool Clamping
Fine-tune the clamping reach on-site by dialling the extend stroke back from 200 mm to 150 mm, ensuring perfect material contact without machining custom spacers.
Transfer Line Diverter
Adjust the diverter arm end-stop externally to handle varying product widths on the fly, using the 50 mm window to shift the push position as needed.
Carton Flap Folder
Set the exact folding depth for different box sizes by turning the external adjuster, relying on the 982 N push force to cleanly fold heavy corrugated material.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-50 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 adjustable stroke is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. For the 200 mm stroke, ensure external guide rails carry the payload to prevent side-load wear on the rod seals. Remember that air pressure alone does not hold the load if air is lost; fit an external rod lock or pilot-operated check valve for suspended 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 JSIJ50X200-50 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. The air port size is G1/4.
The 200 mm stroke is the maximum forward travel. The -50 code means an external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable extend range of 150 to 200 mm. The retract end remains fixed.
