Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-75S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 160mm 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 JSIJ40X160-75S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features a 160 mm nominal stroke that can be shortened on-site by up to 75 mm. An external adjuster lets you fine-tune the extend end position without swapping the actuator, giving a usable forward stroke of 85 to 160 mm while the retract end remains fixed. The hard-anodized aluminum extruded barrel keeps the overall build shorter and more compact than a same-bore ISO 15552 unit. Equipped with a G1/4 port and an M14x1.5 rod thread, it handles about 377 N of real work safely, which translates to lifting roughly 32 kg vertically with a 2:1 margin.
Because this is the -S variant, a built-in piston magnet allows CMSE or DMSE switches to drop directly into the side sensor grooves for precise position detection. The adjustable air cushions at both ends absorb 20.5 mm of impact to protect the mechanics. Note that the cushions only decelerate the moving load; a plain cylinder cannot hold a load if air pressure drops, so fit an external rod lock or pilot-operated check valve for suspended loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-75S Is Used
Adjustable Clamping Press
Dial in the exact 85 to 160 mm extend position on-site to clamp parts of varying thicknesses without re-engineering the fixture.
Variable Transfer Stopper
Use the external adjuster to change where products halt on the line, accommodating different package sizes on the fly.
Compact Sorting Diverter
Fit the shorter JIS profile body into tight conveyor gaps and fine-tune the push distance for reliable package redirection.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X160-75S the Right Cylinder?
When sizing this actuator, compare it against neighbouring bores: a 32 mm bore gives 402 N push at 0.5 MPa, while a 50 mm bore yields 982 N, so the 40 mm at 628 N is ideal for medium-duty tasks. The 75 mm adjustable window is particularly useful when you want a single spare cylinder that can cover several stroke variants on-site, or when machinery requires exact end-position tuning after installation. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. For any stroke of 300 mm or longer, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ40X160-75S FAQ
This 40 mm bore cylinder uses a G1/4 port and provides 628 N push and 528 N pull at 0.5 MPa. At 0.7 MPa it yields 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa.
The 160 mm nominal stroke is the maximum length. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable forward range of 85 to 160 mm. The retract end is fixed, and this mechanism sets the end position rather than locking the load.
