Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-10
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-10 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm 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 JSIJ50X175-10
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic actuator brings precise on-site end-position tuning to your assembly line. The external adjuster lets you shorten the extend stroke by up to 10 mm, yielding a usable range of 165-175 mm while the retract end remains fixed. You can fine-tune the stop without swapping the cylinder, which handles about 589 N of real work or roughly 50 kg lifted vertically with a 2:1 margin. The hard-anodized aluminum profile barrel keeps the total length shorter than a same-bore ISO 15552 unit, and the G1/4 port matches the standard 50 mm JIS layout.
This double-acting single-rod unit relies on adjustable air cushions at both ends to decelerate the 20 mm piston rod smoothly. Because this specific SKU lacks a magnet, it cannot accept CMSE or DMSE sensors for position detection. Note that the cushion and external stop only manage motion; they do not hold a load on air loss, so fit an external rod lock or pilot-operated check valve if you need strict drop prevention.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-10 Is Used
Press Fit Dialing
Micro-adjust the 10 mm extend window on-site to set the exact insertion depth for light-duty bearing press fits without changing the tooling.
Variable Length Stops
Act as a retractable package stop on a conveyor, tweaking the extend position to accommodate slightly different carton lengths on the fly.
Compact Ejector
Eject parts from a tight machining cell where the shorter JIS profile barrel saves valuable machine envelope compared to standard alternatives.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X175-10 the Right Cylinder?
When sizing this 50 mm bore, step down to a 40 mm bore for lighter duties pushing 628 N at 0.5 MPa, or step up to a 63 mm bore for heavier loads pushing 1559 N. The 10 mm adjustable window is ideal for sharing a single spare across slightly different stroke variants, letting mechanics dial in the exact 165-175 mm extend position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because this base SKU has no magnet, you must choose an -S variant if you require CMSE/DMSE sensor tracking. For any stroke at or above 300 mm, always use a external guide rail to prevent side-load wear on the rod seal.
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 JSIJ50X175-10 FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The cylinder features a G1/4 port and a 20 mm piston rod.
The -10 indicates an external adjuster that shortens the extend stroke by up to 10 mm on-site. The nominal 175 mm stroke is the maximum, giving a usable extend range of 165-175 mm, while the retract end remains fixed. This stop sets the end position and is not a load lock.
