Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 700mm stroke, G1/2 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 JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S
Delivering 6136 N of push force at 0.5 MPa, this large-bore JIS actuator brings heavy-duty power to a hard-anodized aluminum profile barrel that is noticeably more compact than a same-bore ISO 15552 unit. The G1/2 port feeds a 32 mm piston rod, and the built-in magnet (-S) accepts CMSE/DMSE sensors in the side grooves for precise position detection.
An external stop screw lets you trim the 700 mm extend stroke on-site by up to 10 mm, giving a usable 690-700 mm window for fine-tuning the end position without swapping the cylinder. In practical terms it handles a safe working load of about 3682 N, or roughly 313 kg lifted vertically with a 2:1 margin. The retract end remains fixed, and the 33 mm adjustable air cushions decelerate the heavy payload smoothly.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S Is Used
Heavy Pallet Lift
Raises 313 kg palletized loads vertically using the full 700 mm stroke, relying on the 10 mm fine-tune window to set the exact discharge height.
Bulk Material Diversion
Pushes heavy aggregate bins off a main line, using the adjustable end-stop to sync the push distance with varying pallet widths.
High-Bay Ejection
Ejects dense cartons from a top-tier rack, using the compact JIS profile to save valuable vertical machine space.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S the Right Cylinder?
When sizing this actuator, stepping down to a 100 mm bore drops the 0.5 MPa push force to 3927 N, while this 125 mm bore tops out at a theoretical 1251 kgf at 1.0 MPa. The -10 mm adjustable window is ideal for sharing one spare across slightly different stroke variants or dialing in a final end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the 700 mm stroke is long, always support the load with an external guide to prevent rod bending and excessive side loading. The -S variant provides the magnet for CMSE/DMSE switches; a non-S SKU cannot take a sensor.
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 JSIJ100~125 Adjustable Cylinder JSIJ125X700-10S FAQ
At 0.5 MPa it provides 6136 N push and 5734 N pull. At 0.7 MPa it provides 8590 N push and 8028 N pull. The theoretical maximum force is 1251 kgf at 1.0 MPa.
The nominal 700 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 10 mm, yielding a usable range of 690-700 mm. The retract end is fixed, and this stop is for position tuning, not load holding.
