Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-40S 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 JSIJ50X200-40S
Generating about 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 on the floor. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. An external stop screw lets you trim the extend stroke by up to 40 mm on site, so the usable forward travel spans 160 to 200 mm while the retract end stays fixed.
The -S suffix means a built-in piston magnet is present, ready for CMSE or DMSE reed and electronic switches that clip into the side grooves. With a practical safe working load of roughly 589 N, it handles about 60 kg lifted vertically with a 2:1 safety margin. Pneumatically it runs at 30-800 mm/s through a G1/4 port, and the adjustable air cushions absorb 20.5 mm of impact at each end. Remember that the stop screw sets position only; you need an external rod lock or pilot-operated check valve to hold a load against air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-40S Is Used
Variable-Length Cutoff
Dial in the 160 to 200 mm extend stroke on a pneumatic shear to cut different material lengths without physically changing the actuator.
Adjustable Pressing
Fine-tune the downstroke end position for pressing bearings, ensuring perfect contact force without repositioning the entire fixture.
Format Changeovers
Quickly alter the extend reach on a packaging conveyor diverter to handle different carton widths on the fly using the external adjuster.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-40S the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm gives 628 N push at 0.5 MPa, while a 63 mm jumps to 1559 N. The 200 mm nominal stroke here is well under the 1200 mm maximum, but for any travel at or over 300 mm you should use a guide rail to prevent side-load wear. The -40 mm adjuster is ideal when you want one shared spare for several stroke lengths, or when a machine setup needs fine end-position tweaking without swapping the cylinder. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this is an -S SKU, it accepts CMSE/DMSE sensors directly; a non-S version cannot take a sensor.
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 JSIJ50X200-40S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it delivers 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 nominal stroke is 200 mm, which is the maximum forward travel. An external stop screw lets you shorten the extend stroke on site by up to 40 mm, giving a usable range of 160 to 200 mm. The retract end is fixed, and this mechanism sets position only—it does not lock the load.
