Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 500mm 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 JSIJ50X500-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for tasks that need exact end-position tuning. The external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 450-500 mm while the retract end remains fixed. You can fine-tune the stroke without swapping the whole unit. The hard-anodized aluminium barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder. It uses a G1/4 port and a 20 mm rod.
The -S suffix means a built-in piston magnet is present, ready for CMSE/DMSE switches that drop directly into the side grooves. In practical terms it handles about 589 N of safe working load, which is roughly 50 kg lifted vertically with a 2:1 margin. The adjustable air cushions decelerate the piston near the ends, but a plain cylinder does not hold load on air loss. For a held load you need an external rod lock or a pilot-operated check valve.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50S Is Used
Conveyor Diverter Tuning
Dial in the exact 450-500 mm extend reach to push varying box sizes onto parallel conveyor lanes without changing the cylinder.
Vertical Lift Gate
Lifts a 50 kg gate using the 982 N push force at 0.5 MPa, using the external adjuster to set the precise open height.
Press Pin Insertion
Sets a hard mechanical stop for pin insertion depth, allowing operators to shorten the extend stroke by up to 50 mm for different batch heights.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X500-50S the Right Cylinder?
Size this 50 mm bore against its neighbours: a 40 mm gives 628 N push at 0.5 MPa, while a 63 mm jumps to 1559 N. This model sits in the middle, offering 982 N push and 825 N pull at 0.5 MPa. The -50 mm adjuster is ideal when you need to dial in a precise extend stop on-site or want a shared spare across stroke variants. Mounting options include FA, LB, TC, TCM1 and TCM2. Because the stroke is 500 mm, add external guides to prevent rod bending and manage side loads. The -S magnet supports CMSE/DMSE sensors for position feedback.
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 JSIJ50X500-50S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. It uses a G1/4 port.
The nominal 500 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, giving a usable range of 450-500 mm. The retract end is fixed. This stop sets the end position and is not a load lock.
