Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-50 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 JSIJ50X175-50
Generating about 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site flexibility to fixed-stroke automation. The hard-anodized aluminium barrel keeps the total length shorter than a same-bore ISO 15552 unit. A G1/4 port feeds the double-acting single rod, which drives across a 175 mm maximum stroke.
The external -50 mm adjuster lets you shorten the extend stroke down to 125 mm without changing the cylinder, while the retract end remains fixed. This on-site tuning handles roughly 589 N of safe working load, lifting about 50 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-50 Is Used
End-Position Tuning
Dial in the exact extend stop between 125 mm and 175 mm on-site to perfect part ejection without swapping hardware.
Transfer Diverter
Shorten the extend stroke by up to 50 mm to deflect packages of varying sizes accurately onto secondary belts.
Vertical Lift Stop
Lift roughly 50 kg loads vertically, adjusting the upper end position mechanically to suit different shelf heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-50 the Right Cylinder?
Size this 50 mm bore against its neighbours: the 40 mm yields 628 N push at 0.5 MPa, while the 63 mm jumps to 1559 N. The JSIJ mounting set covers Basic, FA, LB, TC, TCM1, and TCM2. The -50 mm adjuster is ideal for sharing a spare across stroke variants or fine-tuning the end position. For any stroke over 300 mm, add an external guide to absorb side loads. Because this plain cylinder has no -S suffix, it cannot accept magnetic switches.
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 JSIJ50X175-50 FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it yields 1374 N push and 1154 N pull. The theoretical maximum is 200 kgf at 1.0 MPa. The air port is G1/4.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 125-175 mm. The retract end is fixed. This stop sets the end position and is not a load lock; for holding a load on air loss, use an external rod lock or pilot-operated check valve.
