Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-75 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 JSIJ50X200-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site flexibility to your stroke length. The hard-anodized aluminum extruded barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit, all without external tie rods. A G1/4 port feeds the double-acting single-rod system, driving a 20 mm piston rod with M18x1.5 threading and 20.5 mm adjustable air cushions at both ends.
The -75 code defines an external stop-screw window that shortens the extend stroke by up to 75 mm on-site, giving a usable forward range of 125 to 200 mm while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder, and it handles a safe working load of about 589 N, lifting roughly 50 kg vertically with a 2:1 margin. Note that this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors; you would need the -S variant for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-75 Is Used
Dial-In Clamping
Use the 75 mm extend window to fine-tune the exact clamping contact point on varying part widths without machining new stops.
Transfer Diverter
Adjust the pusher extension on-site to deflect different package sizes on a transfer line, ensuring positive routing without overtravel.
Vertical Lift Stop
Set a precise lower pick position for a 50 kg lift, using the external adjuster to change the extend reach while relying on a check valve for holding.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-75 the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore raises it to 1559 N. The adjustable stroke feature is ideal for sharing a single spare across multiple stroke variants or dialing in exact end positions during machine commissioning. You can mount it via Basic, FA, LB, TC, TCM1, or TCM2 brackets. Because the 200 mm stroke exceeds the 300 mm threshold where side-load risks increase, always guide the load along the rod axis to prevent binding. Finally, a plain cylinder does not hold load on air loss—the cushion only decelerates—so fit an external rod lock or pilot-operated check valve if you need strict 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 JSIJ50X200-75 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 with an M18x1.5 thread, and 20.5 mm adjustable air cushions. Operating speed ranges from 30-800 mm/s.
The -75 designates a 75 mm external adjustment window. The nominal 200 mm stroke is the maximum extend length, and you can shorten the forward stroke on-site by up to 75 mm, yielding a usable extend range of 125 to 200 mm. The retract end remains fixed, and this stop-screw mechanism sets end position rather than locking the load.
