Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-100S
The AirTAC Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø125mm bore and 150mm 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 JSIJ125X150-100S
Delivering 6136 N of push force at 0.5 MPa, this 125 mm bore JIS actuator brings heavy-duty motion into a compact hard-anodized aluminium profile barrel that is noticeably shorter than a same-bore ISO 15552 unit. The G1/2 port feeds a 32 mm rod, and the integrated -S piston magnet hosts CMSE or DMSE switches in the side grooves for precise position feedback.
The external stop screw lets you trim the extend stroke by up to 100 mm on site, dropping the usable forward travel from the 150 mm maximum down to 50 mm without swapping the cylinder. It handles about 3682 N of real work safely, which means roughly 313 kg lifted vertically with a 2:1 margin. Remember the retract end is fixed, and the adjustable air cushions only decelerate the load; use an external rod lock or pilot-operated check valve if you need to hold a suspended weight.

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-100S Is Used
Heavy Pallet Lift
Raises loaded pallets with a safe working load around 3682 N, using the 100 mm adjuster to fine-tune the lift height to the deck.
Press End-Positioning
Feeds heavy blanks into a press, trimming the 150 mm extend stroke back exactly to the material thickness for consistent seating.
Divertor Gate Actuation
Drives a high-mass sorting gate on a conveyor, relying on the 33 mm adjustable cushions to decelerate the 32 mm rod smoothly.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ125X150-100S the Right Cylinder?
This 125 mm bore sits at the top of the JSIJ range; if 8590 N at 0.7 MPa is excessive, step down to the 100 mm bore for 5497 N. The 100 mm adjustable window is ideal for sharing one spare across multiple stroke variants, letting you fine-tune the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. Because side loads damage seals, always guide the rod for any stroke reaching or exceeding 300 mm.
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 JSIJ125X150-100S FAQ
It pushes 6136 N and pulls 5734 N at 0.5 MPa, pushes 8590 N and pulls 8028 N at 0.7 MPa, with a theoretical max of 1251 kgf at 1.0 MPa. The air port is G1/2.
The nominal 150 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke by up to 100 mm on site, giving a usable forward travel of 50 to 150 mm. The retract end remains fixed.
