Airtac JSI Series Standard Cylinder JSI50X800SH
The AirTAC Airtac JSI Series Standard Cylinder JSI50X800SH is a genuine double acting 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 JSI Series Standard Cylinder JSI50X800SH
Delivering 982 N of push force at 0.5 MPa, the AirTAC JSI50X800SH is a double-acting JIS-standard profile cylinder built for long-reach automation. Its extruded hard-anodized aluminum barrel omits external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore. The internal two-way piston seal retains grease for low-friction service life.
This 800 mm stroke variant includes a piston magnet for CMSE or DMSE sensors that drop directly into the side grooves. Plan for roughly 589 N of actual work at 0.5 MPa, which translates to lifting about 50 kg vertically with a 2:1 safety margin. The G1/4 port and M18x1.5 rod thread handle flows up to 800 mm/s, and an optional high-temp seal variant expands application range.

Where the Airtac JSI Series Standard Cylinder JSI50X800SH Is Used
Long-Reach Part Ejection
Pushes finished molded parts 800 mm out of an injection molding machine to a downstream conveyor using 982 N of thrust.
High-Bay Tray Shuttle
Extends into storage racks to push or retrieve product trays, relying on the compact profile to fit tight vertical aisles.
Pallet Transfer Diverter
Diverts heavy pallets across parallel conveyor lines, utilizing the 50 kg vertical lift capacity for smooth transitions.
Is the Airtac JSI Series Standard Cylinder JSI50X800SH the Right Cylinder?
For lighter duties, the 40 mm bore provides 628 N at 0.5 MPa, while stepping up to the 63 mm bore yields 1559 N if your 50 mm setup lacks thrust. Because this 800 mm stroke creates a long lever arm, use an external guide to prevent rod bending and side-load damage. Note that air loss will cause the piston to drift; the cushions only decelerate the stroke end, so fit an external rod lock or pilot-operated check valve to hold suspended loads.
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 JSI Series Standard Cylinder JSI50X800SH FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it yields 1374 N push and 1154 N pull, with a theoretical maximum of 200 kgf at 1.0 MPa. The air port is G1/4.
It is a JIS-standard profile cylinder featuring an extruded aluminum barrel without external rods, making it shorter and more compact than an ISO 15552 cylinder of the same 50 mm bore.
