Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 700mm 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 JSIJ40X700-75S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder is built for tight machinery. Its extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod design rated for 30-800 mm/s.
The -75 code means an external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable 625-700 mm range while the retract end stays fixed. This lets you fine-tune the end position without swapping the cylinder. It handles about 377 N of real work safely, lifting roughly 32 kg vertically with a 2:1 margin. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-75S Is Used
Sorter Diverter Tuning
Diverter arms on packaging lines use the 75 mm extend window to dial in the exact push distance for varying box widths without changing hardware.
Vertical Shelf Loader
Lifting roughly 32 kg of inventory vertically, the built-in magnet confirms pick-and-place positions via side-groove sensors.
Long-Reach Material Stop
A 700 mm extend stroke pushes workpieces to a machine gate, with the external stop screw adjusting the final resting position on-site.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X700-75S the Right Cylinder?
For sizing, the 32 mm bore offers 402 N push at 0.5 MPa, while the 50 mm jumps to 982 N, so this 40 mm sits perfectly for mid-range jobs. The adjustable stroke is ideal when you need on-site end-position tuning or want a shared spare across stroke variants. JSIJ mounting includes FA, LB, TC, TCM1, and TCM2. Because the stroke is 700 mm, always use external guides to prevent rod bending and side loads. Remember the air cushion only decelerates; use an external rod lock or pilot-operated check valve to hold a load.
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 JSIJ40X700-75S FAQ
It has a G1/4 port. The force ratings are 628 N push and 528 N pull at 0.5 MPa, 879 N push and 739 N pull at 0.7 MPa, with a theoretical max of 128 kgf at 1.0 MPa.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 75 mm, yielding a usable range of 625-700 mm. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
