Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 800mm 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 JSIJ50X800-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder is built for long-reach actuation. The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. It handles about 589 N of real work, which means you can lift roughly 50 kg vertically with a 2:1 safety margin.
The -50 code means an external adjuster can shorten the extend stroke on site by up to 50 mm, giving a usable range of 750-800 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. This -S SKU includes a piston magnet for CMSE/DMSE sensors in the side grooves. Pneumatic connections use a G1/4 port.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-50S Is Used
Long-Reach Diverting
Pushes cartons across a wide belt, using the 50 mm adjuster to dial in the exact 760 mm extend stop for different box sizes.
Vertical Material Lift
Raises a 50 kg tote to a high mezzanine level, benefiting from the compact JIS profile to save vertical headroom.
Packaging Stopper Gate
Cycles a long flap on a wrapping line, tweaking the extend position on site to handle varying product widths.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-50S the Right Cylinder?
For sizing, the neighboring 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N if you need more force. The adjustable stroke is ideal when you need to tune the end position on site or want one spare to cover several stroke variants. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. Because this is an 800 mm stroke, always use an external guide rail to prevent rod bending and side loads. The -S magnet supports CMSE/DMSE switches.
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 JSIJ50X800-50S 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 is 200 kgf at 1.0 MPa. The air port is G1/4.
The nominal 800 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 50 mm on site, giving a usable extend range of 750-800 mm. The retract end is fixed. This sets the end position but does not lock the load.
