Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 50mm 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 JSIJ50X50-10S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder integrates a magnetic piston for position sensing. The hard-anodized aluminium barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. A G1/4 port feeds the double-acting chamber, while adjustable air cushions of 20.5 mm decelerate the rod at each end.
The -10 code means an external stop screw lets you trim the extend stroke by up to 10 mm on-site, yielding a usable 40-50 mm forward travel while the retract end stays fixed. This on-site tuning is ideal for dialing in exact end positions without swapping the cylinder. In practical terms it handles about 589 N of real work safely, which translates to lifting roughly 50 kg vertically with a 2:1 margin. Note that a plain cylinder drifts on air loss; use an external rod lock for held loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10S Is Used
Clamp Position Trimming
Dial in the exact gripping distance on a machining fixture by trimming the extend stroke up to 10 mm on-site, ensuring perfect part contact without shimming.
Transfer Gate Stop
Set a precise 40-50 mm stop position for a diverter gate, using the external adjuster to tune the endpoint exactly to the product profile.
Vertical Lift Stop
Lift a 50 kg carton using the 982 N push force, adjusting the forward stop to match varying package heights without reprogramming the valve.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X50-10S the Right Cylinder?
At 0.5 MPa this 50 mm bore generates 982 N push and 825 N pull, sitting neatly between the lighter 40 mm (628 N) and the heavier 63 mm (1559 N) options. The -10 mm adjustable window is a major selection advantage when you need to fine-tune a 40-50 mm end position on the machine or standardize one spare across slight stroke variants. Mounting choices include Basic, FA, LB, TC, TCM1, and TCM2. The -S suffix means the piston magnet is present, ready for CMSE/DMSE sensors in the side grooves. Because the stroke is only 50 mm, side-load stress is minimal, but any application over 300 mm requires a guide to protect 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 JSIJ50X50-10S FAQ
This 50 mm bore cylinder pushes 982 N and pulls 825 N at 0.5 MPa, and pushes 1374 N while pulling 1154 N at 0.7 MPa. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 air port.
The nominal 50 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 10 mm on-site, giving a usable forward travel of 40-50 mm. The retract end is fixed, and the stop only sets position; it does not lock the load.
