Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40S
The AirTAC Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø80mm bore and 700mm 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 JSIJ80X700-40S
Delivering 2513 N of push force at 0.5 MPa, this 80 mm bore JIS profile cylinder brings pneumatic muscle to tight machinery. Its extruded hard-anodized aluminum barrel omits tie rods entirely, making the body noticeably shorter and more compact than a same-bore ISO 15552 unit. The G3/8 port feeds a robust 25 mm piston rod threaded M22x1.5.
The -40 code means an external adjuster can shorten the extend stroke on-site by up to 40 mm, yielding a usable 660-700 mm forward travel while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. In practice it handles about 1508 N of real work, roughly 128 kg lifted vertically. The -S suffix adds a piston magnet for CMSE/DMSE sensors in the side grooves.

Where the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40S Is Used
Transfer Push-Off Tuning
Dial in the exact 660 to 700 mm push-off distance for varying pallet widths on a packaging line without changing the actuator.
Press Stroke Adjustment
Fine-tune the downward extend end position on a light assembly press by up to 40 mm to accommodate different workpiece heights.
Shared Spare Inventory
Keep one -40 adjustable unit as a universal spare for multiple 80 mm bore machines, shortening the stroke on-site to match the broken unit.
Is the Airtac JSIJ63~80 Adjustable Cylinder JSIJ80X700-40S the Right Cylinder?
When sizing this unit, look at both neighbors: a 63 mm bore gives 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. This 80 mm model sits perfectly in between at 2513 N. The adjustable stroke is ideal for sharing one spare across multiple stroke variants or dialing in final end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 700 mm, always use an external guide rail to prevent rod bending under side loads. Note that the air cushion only decelerates; use an external rod lock or pilot-operated check valve to hold a suspended load.
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 JSIJ80X700-40S FAQ
This 80 mm bore cylinder uses a G3/8 port. It generates 2513 N push and 2268 N pull at 0.5 MPa, rising to 3518 N push and 3175 N pull at 0.7 MPa. The theoretical maximum force is 513 kgf at 1.0 MPa.
The nominal 700 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke on-site by up to 40 mm, giving a usable range of 660-700 mm. The retract end remains fixed, and the stop sets position only—it does not lock the load.
