Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 800mm stroke, G3/8 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 JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder features an external adjuster that shortens the extend stroke on-site by up to 50 mm. The nominal 800 mm stroke remains the maximum travel, letting you fine-tune the end position without swapping the actuator. Its extruded hard-anodized aluminium barrel omits tie rods, making the body shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds the 25 mm rod, and the built-in magnet (-S) supports CMSE/DMSE sensors.
In practical terms, the cylinder handles about 1508 N of real work, which is roughly 128 kg lifted vertically with a 2:1 safety margin. The retract end is fixed, while the front stop screw sets the extend window from 750 to 800 mm. Remember that the adjustable air cushion only decelerates the load; a plain cylinder drifts on air loss, so fit an external rod lock or pilot-operated check valve for holding.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S Is Used
Long-Transfer Pusher
Pushes heavy pallets along a 750-800 mm conveyor section, using the 50 mm adjuster to dial the exact push-off distance without repositioning the cylinder.
Multi-Height Lowering
Lowers a 120 kg fixture vertically, relying on the on-site adjuster to set different stopping heights for various product formats on the same line.
Deep-Reach Diverting
Diverts heavy cartons across an 800 mm sorting lane, fine-tuning the extend end position to accommodate varying package widths.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S the Right Cylinder?
Size this 80 mm bore against the neighbouring 63 mm and 100 mm options. The 63 mm yields 1559 N push at 0.5 MPa, whereas this 80 mm hits 2513 N; stepping up to the 100 mm provides 3927 N. The -50 mm adjuster is ideal for sharing one spare across multiple stroke variants or dialing in final end positions on-site. JSIJ mounting choices include FA, LB, TC, TCM1, and TCM2. The -S suffix ensures compatibility with CMSE/DMSE reed or electronic sensors. Because the 800 mm stroke is long, always support the load with an external guide to prevent rod bending and side-load damage.
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 JSIJ63~80 Adjustable Cylinder JSIJ80X800-50S FAQ
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa it provides 3518 N push and 3175 N pull. The theoretical maximum force is 513 kgf at 1.0 MPa. This 80 mm bore unit uses a G3/8 air port and a 25 mm piston rod.
The external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 750 to 800 mm. The nominal 800 mm stroke is the maximum travel, and the retract end remains fixed. This mechanism sets the end position and does not lock the load.
