Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-75S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-75S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 350mm 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 JSIJ80X350-75S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS actuator brings on-site flexibility to demanding pneumatics. The hard-anodized aluminum profile barrel makes it shorter and more compact than a same-bore ISO 15552 cylinder, while the G3/8 port feeds a 25 mm piston rod. It handles about 1508 N of real work safely, which means roughly 128 kg lifted vertically with a 2:1 margin.
The -75 code means an external adjuster can shorten the extend stroke by up to 75 mm on-site, giving a usable range of 275-350 mm without swapping the cylinder. This SKU includes the -S magnet for CMSE/DMSE sensors that drop directly into the side grooves. Note that the air cushion only decelerates the load; use an external rod lock or pilot-operated check valve if you need to hold a load on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-75S Is Used
Transfer Diverter
Fine-tune the 350 mm extend position by up to 75 mm on-site to perfectly align a diverter gate without machining new mounts.
Press Clamping
Clamp parts with 2513 N of force at 0.5 MPa, using the external stop screw to dial in the exact material thickness.
Pallet Stopper
Act as an adjustable height stopper on a packaging line, shortening the stroke from 350 mm to 275 mm as pallet sizes change.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X350-75S the Right Cylinder?
When sizing, the 63 mm bore offers 1559 N push at 0.5 MPa for lighter duties, while the 100 mm bore jumps to 3927 N if you need more muscle. The 80 mm bore here provides a strong middle ground. The -75 mm adjustable window is ideal for fine-tuning end positions on-site or sharing a single spare across multiple stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 350 mm, always use external guides to prevent rod bending and manage side 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 JSIJ63~80 Adjustable Cylinder JSIJ80X350-75S FAQ
At 0.5 MPa it pushes 2513 N and pulls 2268 N. At 0.7 MPa it pushes 3518 N and pulls 3175 N. The theoretical maximum is 513 kgf at 1.0 MPa. It uses a G3/8 air port and a 25 mm piston rod with an M22x1.5 thread.
The nominal 350 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 75 mm on-site, giving a usable range of 275-350 mm. The retract end remains fixed, and this mechanism sets end position rather than locking the load.
