Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X275-75
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X275-75 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 275mm 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 JSIJ40X275-75
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built shorter than a same-bore ISO 15552 unit. The hard-anodized aluminum barrel keeps the assembly light, while the G1/4 port matches the bore standard. A 16 mm rod and M14x1.5 thread carry the load.
The -75 code means an external adjuster can shorten the extend stroke on-site by up to 75 mm, giving a usable range of 200 to 275 mm without swapping the cylinder. This on-site tuning is ideal for shared spares across stroke variants. It handles about 377 N of real work, roughly 32 kg lifted vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X275-75 Is Used
Sorter Diverter Tuning
Diverter arms on a packaging line use the 75 mm extend adjuster to dial in the exact push distance for varying carton widths without changing the cylinder.
Clamp Position Setup
A machining cell shortens the extend stroke from 275 mm down to 220 mm on-site to seat a new fixture against the hard stop precisely.
Shared Spare Inventory
Maintenance teams stock one 275 mm unit and adjust the external screw down to 200 mm to cover multiple lower-stroke machines in the facility.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X275-75 the Right Cylinder?
If 628 N push at 0.5 MPa is too light, step up to the 50 mm bore for 982 N; if it is too heavy, drop to the 32 mm bore for 402 N. The adjustable window shines when you need fine end-position tuning on-site or want a single spare covering several stroke lengths. Mounting options include FA, LB, TC, TCM1, and TCM2. For this 275 mm stroke, guide the load to prevent side-load wear on the 16 mm rod. Because this is a no-S model, it cannot accept magnetic 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 JSIJ40X275-75 FAQ
At 0.5 MPa it pushes 628 N and pulls 528 N. At 0.7 MPa it pushes 879 N and pulls 739 N. The theoretical max force is 128 kgf at 1.0 MPa. The air port is G1/4.
The nominal 275 mm extend stroke is the maximum. An external adjuster shortens the extend stroke on-site by up to 75 mm, yielding a usable range of 200 to 275 mm; the retract end is fixed. This mechanism only sets the end position and decelerates the piston via air cushions. It does not hold the load on air loss. For a held load, use an external rod lock or pilot-operated check valve.
