Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40 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 JSIJ40X600-40
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for applications needing exact end-position tuning on site. An external adjuster lets you shorten the extend stroke by up to 40 mm, giving a usable range of 560-600 mm while the retract end stays fixed. The extruded hard-anodized aluminium barrel keeps the overall body more compact than an ISO 15552 cylinder of the same bore. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin.
This double-acting single-rod unit uses a G1/4 port and a 16 mm rod with an M14x1.5 thread. Because this SKU lacks the -S magnet option, it cannot take a CMSE or DMSE sensor. The adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load. For vertical holding you need an external rod lock or pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40 Is Used
Conveyor End-Stop Tuning
Dial in the exact 560 to 600 mm pusher distance on a transfer line without machining new hard stops.
Press Pin Insertion
Fine-tune the downstroke end position to seat pins perfectly across varied material thicknesses.
Shared Spare Inventory
Keep one cylinder on the shelf and adjust the extend stroke on site to fit multiple machine layouts.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X600-40 the Right Cylinder?
When sizing, the neighbouring 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm bore steps up to 982 N if you need more power. The -40 mm adjustable window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the extend endpoint without swapping the cylinder. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. With a 600 mm stroke, you must support the load with external guides to prevent rod bending and excessive side loading. Remember this specific SKU has no magnet and cannot host a sensor.
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 JSIJ40X600-40 FAQ
This 40 mm bore cylinder pushes 628 N and pulls 528 N at 0.5 MPa. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical maximum force is 128 kgf at 1.0 MPa. It uses a G1/4 air port.
The external stop screw lets you shorten the extend stroke on site by up to 40 mm. The nominal 600 mm stroke is the maximum, so the usable extend range is 560-600 mm. The retract end remains fixed.
