Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-40 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 JSIJ50X175-40
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend tuning to mid-range pneumatics. Its extruded hard-anodized aluminium barrel skips external tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod design rated for 30-800 mm/s speeds.
The external stop screw provides a 40 mm shortening window, letting you set the usable extend stroke anywhere from 135 to 175 mm without swapping the cylinder. This fine-tunes the end position on-site and lets one spare cover multiple stroke variants. In practice it handles about 589 N of real work, roughly 50 kg lifted vertically with a 2:1 margin. Note this plain SKU lacks a magnet and cannot take a CMSE/DMSE sensor.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-40 Is Used
Adjustable Clamping Stop
Dial in the 135 to 175 mm extend reach on a machining fixture to clamp varying part widths without swapping actuators.
Transfer Pusher Tuning
Fine-tune the push-off distance on a conveyor line using the 40 mm external stop screw to handle different box sizes.
Compact Divert Gate
Fit a shorter JIS-profile diverter into tight sorting lanes and adjust the gate stroke on-site to match package heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-40 the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm bore gives 628 N push at 0.5 MPa, while a 63 mm bore jumps to 1559 N. The 40 mm adjustable window is ideal when you need to share a single spare cylinder across slightly different stroke variants or trim the extend end-position on the fly. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this SKU lacks the -S magnet, it cannot support position sensing; add the -S variant for CMSE/DMSE switches. For any stroke over 300 mm, always guide the load to prevent rod side-loading and premature seal wear.
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 JSIJ50X175-40 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a 20 mm rod, an M18x1.5 rod thread, a G1/4 port, and 20.5 mm adjustable air cushions at both ends.
The nominal 175 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 135 to 175 mm. The retract end is fixed. This stop only sets the end position; it does not lock the load, so use an external rod lock or pilot-operated check valve if you need to hold a load against air loss.
