Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-10S 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 JSIJ50X600-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend adjustability to long-stroke automation. The external stop screw provides a 10 mm shortening window, letting you fine-tune the extend end position down to a 590 mm usable stroke without swapping the actuator. Because the retract end remains fixed, the return stroke stays consistent while you dial in the extend stop.
The hard-anodized aluminum extruded body keeps the overall length shorter than a same-bore ISO 15552 unit. A built-in piston magnet (-S) accepts CMSE or DMSE reed and electronic switches in the side grooves. With a 589 N safe working load, it lifts about 50 kg vertically with a 2:1 margin. The G1/4 ports feed the 20.5 mm adjustable air cushions at both ends. Note that plain air cylinders drift on pressure loss, so fit an external rod lock or pilot-operated check valve if you need to hold a suspended load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-10S Is Used
Conveyor Diverter Fine-Tuning
Adjusts the 600 mm extend stroke by up to 10 mm on-site to perfectly align a diverter gate without changing the fixed retract position.
Vertical Lift Positioning
Lifts roughly 50 kg vertically with a 2:1 safety margin, using the external stop screw to dial in the exact raise height for varying pallet stacks.
Long-Reach Press Dwell
Uses the 590-600 mm extend window to set a precise dwell position on a remote press head, keeping the JIS profile body compact in a tight cell.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-10S the Right Cylinder?
For sizing, the 50 mm bore sits comfortably between the 40 mm (628 N push at 0.5 MPa) and the 63 mm (1559 N push at 0.5 MPa) options. The 10 mm extend adjuster is ideal for sharing a spare across stroke variants or making quick on-site end-position tweaks without disassembling the machine. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. The -S suffix means the piston magnet is present for CMSE/DMSE sensors. Because the 600 mm stroke is long, always use an external guide rail to prevent rod bending and side-load damage.
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 JSIJ50X600-10S 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. This 50 mm bore model uses G1/4 air ports.
The nominal 600 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, giving a usable extend range of 590-600 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load.
