Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 500mm 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 JSIJ50X500-30S
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend tuning to a 500 mm stroke. The external stop screw provides a 30 mm shortening window, letting you dial the usable extend stroke down to 470 mm without swapping the actuator. Because the nominal 500 mm is the maximum, you can fine-tune the end position perfectly in the field. It handles about 589 N of real work safely, which means you can lift roughly 50 kg vertically with a 2:1 margin.
Built with an extruded hard-anodized aluminum barrel, the body is noticeably shorter and more compact than an ISO 15552 cylinder of the same bore. The -S suffix means a piston magnet is fitted, allowing CMSE or DMSE switches to drop directly into the side sensor grooves. Pneumatically it connects via a G1/4 port, runs at 30-800 mm/s, and uses adjustable 20.5 mm air cushions at both ends to decelerate the payload smoothly.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-30S Is Used
Transfer Push-Off Tuning
Dial in the exact 470-500 mm push-off distance on a conveyor line using the external adjuster, ensuring product diverts cleanly without repositioning the cylinder mount.
Vertical Lift Stops
Lift approximately 50 kg of inventory vertically, using the 30 mm adjuster to set precise upper stopping heights for varying pallet stack thicknesses.
Press Clamping Positioning
Clamp parts securely with 982 N of force at 0.5 MPa, making on-site adjustments to the extend end-position to accommodate different material thicknesses.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-30S the Right Cylinder?
When sizing this 50 mm bore, step down to a 40 mm cylinder if your force needs drop below 628 N push at 0.5 MPa, or step up to a 63 mm bore for 1559 N. The adjustable 470-500 mm extend window is ideal for synchronizing multiple actuators or sharing a spare across slightly different stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 500 mm, always support the load with an external guide rail to prevent rod bending and side-load wear. The -S magnet enables precise end-of-stroke sensing with CMSE/DMSE switches.
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 JSIJ50X500-30S FAQ
This 50 mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa. 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 G1/4 port and features a 20 mm piston rod with an M18x1.5 rod-end thread.
The -30 code means an external stop screw lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 470-500 mm (the 500 mm nominal stroke is the maximum). The retract end remains fixed. This stop only sets the end position; it is not a load lock. A plain cylinder drifts on air loss, so for holding a load you need an external rod lock or pilot-operated check valve.
