Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-50
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-50 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 JSIJ40X175-50
Delivering 628 N of push force at 0.5 MPa, this 40 mm bore JIS profile cylinder features a 175 mm nominal stroke that can be fine-tuned down by 50 mm directly on-site. The external adjuster lets you set the extend end position anywhere from 125 to 175 mm without swapping the actuator, making it ideal for dialing in precise stops. Built with an extruded hard-anodized aluminum barrel and no exposed tie rods, the body is significantly shorter and more compact than a same-bore ISO 15552 unit.
This double-acting single-rod actuator handles a safe working load of about 377 N, which translates to lifting roughly 32 kg vertically with a 2:1 safety margin. It uses a G1/4 port, a 16 mm rod with an M14x1.5 thread, and adjustable 20.5 mm air cushions at both ends. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE sensors for position detection.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-50 Is Used
Adjustable Clamping Stop
Dial in the perfect 125 to 175 mm extend distance on a machining line to clamp varying part widths without changing the entire actuator.
Transfer Line Diversion
Fine-tune the pusher end position on-site to deflect packages of different sizes smoothly onto secondary routing belts.
Vertical Lift Dampening
Lift loads up to 32 kg and rely on the 20.5 mm adjustable air cushions to decelerate the payload smoothly at the extend end.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ40X175-50 the Right Cylinder?
When sizing this model, the 32 mm bore offers a lighter 402 N push at 0.5 MPa, while stepping up to the 50 mm bore yields 982 N if your application demands more thrust. The 50 mm adjustable window is perfect for sharing a single spare across multiple machines that need slightly different extend lengths, allowing on-site end-position tuning without disassembly. You can mount it using the basic body, FA, LB, TC, TCM1, or TCM2 brackets. For any stroke at or above 300 mm, always guide the load to prevent side-loading 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 JSIJ40X175-50 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.
The nominal 175 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 125 to 175 mm. The retract end remains fixed, and the adjuster sets the end position rather than locking the load.
