Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X150-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X150-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm 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 JSIJ40X150-30
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to mid-range pneumatic setups. The hard-anodized aluminum barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit, while the G1/4 port matches the standard 40 mm sizing. It handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin.
The -30 code means an external adjuster can shorten the extend stroke by up to 30 mm on-site, giving a usable forward range of 120-150 mm without swapping the cylinder. The retract end remains fixed, and the adjustable air cushions at both ends absorb end-of-travel shock. Because this SKU lacks a magnet, it cannot take a CMSE or DMSE sensor; for the -S variant if you need position feedback.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X150-30 Is Used
Clamp Stroke Tuning
Dial in the exact 120-150 mm forward clamping reach on machining fixtures without machining custom spacers.
Transfer Pusher Adjustment
Fine-tune the product push-off distance on a conveyor line as package sizes change, using the external stop screw.
Compact Divert Gate
Fit a short-profile JIS diverter gate in tight machinery gaps where an ISO 15552 cylinder of the same bore would not clear.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X150-30 the Right Cylinder?
When sizing, the neighboring 32 mm bore offers 402 N push at 0.5 MPa for lighter duties, while the 50 mm bore steps up to 982 N if this 40 mm unit is undersized. The 30 mm adjuster window is ideal for fine-tuning the extend end position during commissioning or sharing a single spare across several slightly different stroke variants. JSIJ mounting choices cover Basic, FA, LB, TC, TCM1, and TCM2. For any stroke at or above 300 mm, guide the load externally to prevent rod side-loading and premature seal wear.
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 JSIJ40X150-30 FAQ
This 40 mm bore cylinder pushes 628 N and pulls 528 N at 0.5 MPa, or 879 N push and 739 N pull at 0.7 MPa, with a theoretical maximum of 128 kgf at 1.0 MPa. It uses a G1/4 air port and a 16 mm rod with an M14x1.5 thread.
The nominal 150 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, yielding a usable forward range of 120-150 mm. The retract end is fixed. This stop sets the end position and is not a load lock; a plain cylinder drifts on air loss, so use an external rod lock or pilot-operated check valve to hold a suspended load.
