Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-50S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 175mm 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 JSIJ80X175-50S
Generating 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings on-site flexibility to your tooling. Its external stop screw lets you shorten the extend stroke by up to 50 mm, giving a usable range of 125 to 175 mm without swapping the actuator. The hard-anodized aluminum barrel omits external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. It handles about 1508 N of real work, which means you can vertically lift roughly 128 kg with a 2:1 safety margin.
Because this SKU includes the -S magnet, you can drop CMSE or DMSE reed and electronic switches directly into the side grooves for precise positioning. The G3/8 port feeds the 25 mm rod to deliver 3518 N at 0.7 MPa. Remember that the adjustable stop sets the end position but does not lock the load; you will need an external rod lock or pilot-operated check valve to hold a suspended weight securely on air loss.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-50S Is Used
Variable Depth Forming Press
Dial in the exact 125 to 175 mm forming depth on-site using the external stop screw, avoiding cylinder swaps when material thickness changes.
Adjustable Transfer Diverter
Fine-tune the extend position to route different package sizes on a packaging line, using the integrated -S magnet and CMSE sensors to confirm the arm location.
Tiered Pallet Stopper
Shorten the extend stroke by up to 50 mm to accommodate varying pallet heights without repositioning the hard-anodized profile barrel.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X175-50S the Right Cylinder?
When sizing this actuator, the 80 mm bore sits in the upper-middle range. If 2513 N at 0.5 MPa is excessive, step down to the 63 mm bore for 1559 N. If you need more power, the 100 mm bore provides 3927 N. The 50 mm adjuster is ideal when you need to fine-tune a clamping end position across multiple stations or share a single spare cylinder across several stroke variants. You can mount it using FA, LB, TC, TCM1, or TCM2 brackets. For this 175 mm stroke, ensure you use a guide rail to prevent side-load damage to the M22x1.5 rod thread.
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 JSIJ80X175-50S 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. This 80 mm bore unit uses a G3/8 port.
The nominal 175 mm extend stroke is the maximum. The external stop screw lets you shorten the extend travel by up to 50 mm on-site, yielding a usable extend range of 125 to 175 mm. The retract end remains fixed.
