Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 150mm 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 JSIJ50X150-75S
Generating 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder delivers an on-site extend-stroke adjustment window of 75 mm. The external stop screw lets you fine-tune the end position down from the 150 mm maximum to 75 mm without swapping the actuator. It is a hard-anodized aluminum extrusion that is physically shorter and more compact than a same-bore ISO 15552 unit.
Fitted with a G1/4 port and an M18x1.5 rod thread, the unit includes a -S piston magnet for CMSE/DMSE sensors. It handles a safe working load of about 589 N, which is roughly 50 kg lifted vertically with a 2:1 margin. The retract end remains fixed, and the 20.5 mm adjustable air cushions only decelerate the piston near the ends.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-75S Is Used
Clamp Stroke Tuning
Dial in the exact clamping contact point on machined parts by shortening the 150 mm extend stroke up to 75 mm on-site.
Variable Transfer Stop
Adjust the physical stop position for different package widths on a conveyor line without changing out the entire cylinder.
Shared Spare Inventory
Keep one actuator in stock and set the extend stroke anywhere from 75 to 150 mm to cover multiple machine maintenance requirements.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-75S the Right Cylinder?
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa while the 63 mm bore steps up to 1559 N, so the 50 mm bore sits perfectly in the middle for moderate loads. The 75 mm adjuster is ideal for sharing a single spare across multiple stroke variants or dialing in a precise end position on the machine. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet allows drop-in CMSE/DMSE switches. For any stroke at or above 300 mm, always use a guide rail to prevent 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 JSIJ50X150-75S 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 maximum force is 200 kgf at 1.0 MPa. The air port is G1/4 and the rod thread is M18x1.5.
The nominal 150 mm stroke is the maximum extend length. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable range of 75 to 150 mm. The retract end is fixed, and this stop only sets the end position rather than locking the load.
