Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-100
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-100 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 JSIJ50X175-100
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built shorter and more compact than a same-bore ISO 15552 unit. The hard-anodized aluminum extruded barrel keeps the assembly light while withstanding industrial wear. It operates on a G1/4 port and features a 20 mm piston rod with an M18x1.5 thread. Air cushions at both ends provide 20.5 mm of deceleration.
The external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, giving a usable forward range of 75 to 175 mm without changing the cylinder itself. This on-site tuning is ideal for dialing in exact end positions. Based on the 0.5 MPa push rating, it handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Note this plain SKU lacks a magnet and cannot take a CMSE or DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-100 Is Used
Press Fit Depth Tuning
Dial in the exact insertion depth of a bearing on-site using the 100 mm adjuster window, avoiding mechanical spacer changes when part tolerances vary.
Variable Length Diverter
Adjust the extend stroke from 75 to 175 mm to deflect different package sizes on a line without swapping out the entire actuator assembly.
Vertical Lift Stop
Lift approximately 50 kg of stock vertically using the 982 N push at 0.5 MPa, setting the precise raise height via the external stop screw.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-100 the Right Cylinder?
When sizing this 50 mm bore, step down to a 40 mm cylinder for lighter duties (528 N pull at 0.5 MPa) or move up to a 63 mm bore if you need 1402 N pull at 0.5 MPa. The 100 mm adjustable window is highly useful when you need to share a spare cylinder across slightly different stroke variants or fine-tune the end position after mechanical mounting. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because the 175 mm stroke is under 300 mm, side-load risks are minimal, but always guide the load for longer extensions. Remember that a plain cylinder does not hold load on air loss; use an external rod lock or pilot-operated check valve for vertical holding.
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 JSIJ50X175-100 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. It uses a G1/4 port, a 20 mm rod, an M18x1.5 rod thread, and 20.5 mm adjustable air cushions at both ends.
The nominal maximum extend stroke is 175 mm. The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 75 to 175 mm. The retract end is fixed. This mechanism only sets the end position and does not lock the load.
