Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-20S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-20S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 175mm 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 JSIJ50X175-20S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features an on-site extend-shortening window of 20 mm. The external adjuster lets you trim the usable extend stroke anywhere from 175 mm down to 155 mm without swapping the actuator, while the retract end remains fixed. Because the nominal stroke acts as the maximum, you can fine-tune the end position precisely during machine commissioning.
Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin. The -S suffix means a built-in piston magnet is present, allowing CMSE or DMSE switches to drop directly into the side grooves for position sensing. Pneumatic connections use a G1/4 port, and adjustable air cushions of 20.5 mm at each end absorb kinetic energy near the stroke limits.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-20S Is Used
End-Stop Trimming
Dial in the exact extend position within the 155-175 mm window during machine setup to perfect a pressing operation without machining new spacers.
Divertor Adjustment
Fine-tune the actuator reach on a sorting line by shortening the extend stroke up to 20 mm to accommodate different package sizes on the fly.
Shared Spare Stock
Keep one cylinder in maintenance inventory and adjust the external stop screw to cover multiple nearby stroke requirements, reducing spare parts complexity.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-20S the Right Cylinder?
When sizing this model, the 50 mm bore sits right between the 40 mm class (628 N push at 0.5 MPa) and the 63 mm class (1559 N push at 0.5 MPa), making it ideal for medium-duty tasks. The 20 mm adjustable window is especially useful when you want a shared spare across slightly different stroke variants or need to dial in an end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Since this SKU includes the -S magnet, it is fully ready for CMSE/DMSE sensors. For any stroke length at or above 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ50X175-20S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull force. 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.
An external stop screw lets you shorten the extend stroke on-site by up to 20 mm. The usable extend range is 155 to 175 mm, with 175 mm being the maximum nominal stroke. The retract end is fixed. This mechanism sets the end position and does not lock the load.
