Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 450mm 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 JSIJ50X450-75S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is more compact than a same-size ISO 15552 unit. The hard-anodized aluminum barrel keeps the build short, while the G1/4 port supplies air to the double-acting single rod. It handles about 589 N of real work, roughly 50 kg lifted vertically with a 2:1 margin.
The -75S code means an external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 375 to 450 mm without changing the cylinder. The retract end stays fixed. The built-in magnet works with CMSE/DMSE sensors in the side grooves. The 20.5 mm adjustable air cushions only decelerate the piston near the ends; use an external rod lock or pilot-operated check valve to hold a load.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-75S Is Used
Sorter Diverter Tuning
Fine-tune the extend stop by up to 75 mm on-site to perfectly align a package diverter arm without swapping cylinders.
Variable Stop Positioning
Adjust the extend stroke from 375 to 450 mm to handle different pallet sizes on a shared pneumatic line.
Press Stroke Setup
Dial in the exact end position for a light pressing task, using the G1/4 port and 982 N push force at 0.5 MPa.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-75S the Right Cylinder?
For lighter work the 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore steps up to 1559 N if you need more force. The 50 mm bore hits a solid middle ground. The -75 mm adjust window is perfect for tuning end positions on-site or sharing one spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 450 mm, use external guides to prevent rod bending and side loads. The -S magnet allows CMSE/DMSE switches for position sensing.
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 JSIJ50X450-75S FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical max force is 200 kgf at 1.0 MPa. It uses a G1/4 port and runs at 30-800 mm/s.
The nominal 450 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 375 to 450 mm. The retract end is fixed, and the stop only sets position, not a load lock.
