Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 175mm 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 JSIJ40X175-40S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 40 mm. The nominal 175 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its hard-anodized aluminium extruded barrel omits tie rods entirely, making the overall body shorter and more compact than a same-bore ISO 15552 unit. It handles about 377 N of real work safely, which translates to roughly 32 kg lifted vertically with a 2:1 margin.
Because this is the -S variant, a built-in piston magnet lets you drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise position sensing. Pneumatic connections use a G1/4 port, while a 20.5 mm adjustable air cushion at each end decelerates the moving load smoothly. Remember that the cushion only slows the piston near the end of travel; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve if you need to hold a load securely.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-40S Is Used
Variable Stroke Clamping
Dial in the exact clamping contact point on machined parts by shortening the extend stroke up to 40 mm without changing the physical cylinder mount.
Transfer Pusher Adjustment
Accommodate different product lengths on a packaging line by tweaking the extend end position on-site to alter the push-off distance precisely.
Compact Divert Gate
Fit a shorter JIS-profile actuator into tight conveyor underframes and use the adjuster to set the exact gate swing distance for sorting goods.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-40S the Right Cylinder?
When sizing this actuator, compare it against neighbouring bores: a 32 mm bore gives 402 N push at 0.5 MPa for lighter duties, whereas a 50 mm bore jumps to 982 N if your payload increases. The 40 mm bore hits a sweet spot for moderate tasks. The 40 mm adjustable window is ideal when you need on-site end-position tuning across shared spare parts for different stroke variants. You can mount it using Basic, FA, LB, TC, TCM1, or TCM2 brackets. The included -S magnet supports CMSE/DMSE sensors. For any stroke at or over 300 mm, always use a guide rail to prevent side-load damage to the piston rod.
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 JSIJ40X175-40S FAQ
At 0.5 MPa it provides 628 N push and 528 N pull. At 0.7 MPa it provides 879 N push and 739 N pull. The theoretical maximum force is 128 kgf at 1.0 MPa. This 40 mm bore model uses a G1/4 air port and features a 16 mm rod with an M14x1.5 thread.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm. With a nominal 175 mm maximum stroke, your usable extend range is 135-175 mm. The retract end remains fixed. This mechanism sets the end position and is not a load lock.
