Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X35-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X35-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø40mm bore and 35mm 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 JSIJ40X35-10S
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder brings precise on-site end-position tuning to tight machinery. Its extruded hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 unit. The external adjuster lets you shorten the extend stroke by up to 10 mm on site, giving a usable range of 25-35 mm without swapping the cylinder.
With a safe working load of about 377 N and a vertical lift capacity near 32 kg with a 2:1 margin, it handles meaningful work in a small footprint. The G1/4 port feeds the double-acting single rod, and the -S suffix means a built-in magnet for CMSE/DMSE sensors in the side grooves. Note that the adjustable stop sets position only; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X35-10S Is Used
Clamp Stroke Trimming
Dial in the exact clamping depth on a fixture by adjusting the extend stroke up to 10 mm shorter than the 35 mm maximum, ensuring perfect material contact without remachining stops.
Compact Sensor Detection
Leverage the built-in -S magnet and CMSE/DMSE switches to confirm part ejection in a tight assembly cell where the short JIS profile barrel saves valuable mounting space.
Transfer Gate Positioning
Fine-tune the extend endpoint of a diverter gate by up to 10 mm on-site to accommodate different package sizes without changing out the entire actuator.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X35-10S the Right Cylinder?
When sizing this actuator, stepping down to a 32 mm bore drops the 0.5 MPa push force to 402 N, while stepping up to a 50 mm bore raises it to 982 N. The 10 mm extend-shortening window is ideal for sharing a spare across slight stroke variants or fine-tuning a final end position during machine commissioning. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. The integrated -S magnet supports CMSE/DMSE switches. For any stroke length at or above 300 mm, always guide the load externally to prevent side-load damage to the rod and 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 JSIJ40X35-10S 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. It uses a G1/4 port and a 16 mm rod.
The 35 mm nominal stroke is the maximum extend length. The external adjuster allows you to shorten the extend stroke on-site by up to 10 mm, yielding a usable extend range of 25-35 mm. The retract end remains fixed, and the adjuster only sets the end position rather than locking the load.
