Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40S 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 JSIJ50X800-40S
Delivering 982 N of push force at 0.5 MPa, this double-acting single-rod profile cylinder brings on-site adjustability to long-stroke tasks. The external stop screw lets you shorten the extend stroke by up to 40 mm, yielding a usable range of 760 to 800 mm, while the retract end remains fixed. This allows fine-tuning of the end position without physically changing the actuator. It handles about 589 N of real work, which translates to safely lifting roughly 50 kg vertically with a 2:1 margin.
Built to JIS standards with an extruded hard-anodized aluminum barrel, the body is shorter and more compact than a same-bore ISO 15552 cylinder. The G1/4 port feeds a 30 to 800 mm/s speed range, and the -S suffix means a built-in magnet is present for CMSE/DMSE sensors in the side grooves. Note that a plain cylinder drifts on air loss; the adjustable air cushions only decelerate near the ends, so fit an external rod lock or pilot-operated check valve for held loads.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40S Is Used
Sorter Diverter Tuning
Fine-tunes the 760 to 800 mm extend reach of a package diverter arm on-site, ensuring parcels deflect cleanly without changing the actuator.
Vertical Lift Gate
Lifts a roughly 50 kg access gate using the 982 N push force, relying on the adjustable stop to set the exact open height.
Long-Reach Packer
Pushes product into a carton over an 800 mm stroke, using the external guide to manage rod bending and the cushion to decelerate.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X800-40S 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, letting you step up or down if 982 N is borderline. The -40 mm adjustable window is ideal when you need to tune the final extend position on-site or want a shared spare across slight stroke variants. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because this is an 800 mm stroke, always support the rod against side-load bending with an external guide to prevent premature wear.
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 JSIJ50X800-40S 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. It uses a G1/4 port.
The external stop screw lets you shorten the extend stroke on-site by up to 40 mm, giving a usable extend range of 760 to 800 mm. The nominal 800 mm stroke is the maximum, and the retract end is fixed. This sets the end position but does not lock the load.
