Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 700mm 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 JSIJ50X700-30
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. Its extruded hard-anodized aluminium barrel omits tie rods, making it shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod mechanism rated for 30-800 mm/s.
The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 670 to 700 mm while the retract end stays fixed. This means you can fine-tune the stop without swapping the cylinder. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30 Is Used
Conveyor Diverter Tuning
Dial in the 670 to 700 mm extend reach to hit a moving product lane precisely without remounting the actuator.
Pallet Stop Adjustment
Shorten the extend stroke by up to 30 mm on-site to accommodate varying pallet depths while using the fixed retract end.
Press Clamping Setup
Fine-tune the clamping end position during machine commissioning, leveraging the 982 N push force at 0.5 MPa.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X700-30 the Right Cylinder?
For sizing, the 50 mm bore sits between the 40 mm (628 N push @0.5 MPa) and 63 mm (1559 N push @0.5 MPa) options. The adjustable -30 mm window is perfect for sharing a single spare across slightly different stroke variants or dialing in final positioning on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 700 mm stroke is long, always use external guides to prevent rod bending and side loads. For position feedback, you must select the -S magnet version for 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 JSIJ50X700-30 FAQ
This 50 mm bore cylinder uses a G1/4 port. It delivers 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 max of 200 kgf at 1.0 MPa.
The external stop screw lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 670 to 700 mm. The nominal 700 mm is the maximum. The retract end is fixed. This stop only sets position; it does not lock the load.
