Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75 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 JSIJ50X600-75
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic actuator brings on-site flexibility to long-trroke tasks. The hard-anodized aluminum profile barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. A G1/4 port supplies air, while adjustable cushions at both ends manage end-of-travel deceleration.
The external adjuster lets you shorten the extend stroke by up to 75 mm right at the machine, giving a usable forward range of 525 to 600 mm without swapping the cylinder. It handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically. Note that this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75 Is Used
Transfer Push-Off
Fine-tunes the 600 mm extend position to push varying box sizes off a belt without repositioning the cylinder mount.
Lift Station Stop
Shortens the extend stroke by 75 mm on-site to set a precise upper lift limit for a 50 kg platform payload.
Pallet Divider
Adjusts the forward stop point on-site to handle different pallet widths while using the full 600 mm retracted clearance.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-75 the Right Cylinder?
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N if you need more authority. The 75 mm extend-shortening window is ideal for sharing a single spare across slightly different stroke variants or fine-tuning the end position during commissioning. You can mount it via Basic, FA, LB, TC, TCM1, or TCM2 brackets. Because the stroke is 600 mm, always use an external guide rail to prevent rod bending and side-load damage. Remember that a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if the load must be held.
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 JSIJ50X600-75 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. It uses a G1/4 air port, a 20 mm rod, and an M18x1.5 rod-end thread.
The nominal 600 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 75 mm on-site, giving a usable forward range of 525 to 600 mm. The retract end remains fixed, and the adjuster only sets the end position, acting as a stop rather than a load lock.
