Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X600-30
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore pneumatic actuator brings on-site flexibility to long-stroke tasks. The hard-anodized aluminum profile barrel keeps the overall body more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 377 N, which means you can lift roughly 32 kg vertically with a 2:1 safety margin.
The external adjuster allows you to shorten the extend stroke by up to 30 mm directly at the machine, giving a usable extend range of 570-600 mm while the retract end remains fixed. You can fine-tune the end position without physically swapping the cylinder. This SKU lacks a magnet and cannot accept CMSE or DMSE sensors, and the G1/4 port matches the 40 mm bore standard. Note that the air cushion only decelerates the piston; it does not hold the load on air loss, so fit an external rod lock for vertical holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-30 Is Used
Conveyor Diverter Timing
Dial in the 30 mm extend window to precisely strike passing packages on a conveyor without repositioning the whole actuator assembly.
Pallet Stopper Adjustment
Fine-tune the stopping face for mixed pallet sizes on a packing line, shortening the 600 mm stroke exactly where the load needs to halt.
Long-Reach Press Down
Lower a light tooling head over a 600 mm gap, tweaking the final 30 mm of downward travel to compensate for varying material thicknesses.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-30 the Right Cylinder?
When sizing this model, the 32 mm bore offers a lighter 402 N push at 0.5 MPa, whereas the 50 mm bore steps up to 982 N if your payload exceeds the 377 N safe working load of this 40 mm unit. The adjustable stroke is highly useful for sharing a single spare across multiple stroke variants or dialing in exact end positions during commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 600 mm, you must support the load with external guides to prevent rod bending and side-load damage. As a non-magnetic SKU, it cannot host position sensors.
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 JSIJ40X600-30 FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa.
An external stop screw lets you shorten the extend stroke on-site by up to 30 mm, yielding a usable extend range of 570-600 mm. The nominal 600 mm stroke is the maximum, and the retract end is fixed.
