Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 600mm 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 JSIJ50X600-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for applications needing exact end-position tuning. The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 550 to 600 mm without swapping the actuator. Its extruded hard-anodized aluminium barrel is noticeably shorter than a same-bore ISO 15552 unit, saving valuable machine space.
The integrated -S piston magnet supports CMSE/DMSE sensors that drop directly into the side grooves for precise position feedback. With a G1/4 port and an M18x1.5 rod thread, it handles a safe working load of roughly 589 N, which translates to lifting about 50 kg vertically with a 2:1 margin. The retract end remains fixed while the adjustable air cushions absorb 20.5 mm of impact at both extremes.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-50S Is Used
Divert Gate Tuning
Fine-tune the extend reach by up to 50 mm on-site to perfectly align a pneumatic divert gate without machining new hard stops.
Variable Pusher Stroke
Adjust the extend position on the fly for packaging lines handling mixed carton lengths, using the 600 mm maximum stroke as your baseline.
Long-Reach Forming Press
Use the 550 to 600 mm extend window to set the exact forming depth on long components, guided by an external rail to prevent rod bending.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-50S the Right Cylinder?
When sizing this actuator, compare it against the neighbouring 40 mm bore, which provides 628 N of push at 0.5 MPa, and the larger 63 mm bore, which yields 1559 N. The 50 mm bore fits neatly in the middle, and the 50 mm adjustable window means you can stock one 600 mm unit to serve several slightly shorter stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 600 mm, always use an external guide rail to prevent rod bending and manage side loads. The -S magnet allows CMSE/DMSE switches for end-of-stroke confirmation.

- ✓ 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 JSIJ50X600-50S FAQ
This 50 mm bore cylinder uses a G1/4 port. It generates 982 N push and 825 N pull at 0.5 MPa, 1374 N push and 1154 N pull at 0.7 MPa, with a theoretical maximum of 200 kgf at 1.0 MPa.
The nominal 600 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable range of 550 to 600 mm. The retract end is fixed. Note that this mechanism only sets the end position; it does not lock the load on air loss.
