Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-50S
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X50-50S is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 50mm 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 JSIJ100X50-50S
The extruded hard-anodized aluminium barrel leaves out external rods, making the body shorter and more compact than a same-bore ISO 15552 unit. A G1/2 port feeds the chamber, while a built-in magnet (-S) lets you drop CMSE or DMSE reed and electronic switches straight into the side grooves.
The -50 code means an external stop screw can shorten the extend stroke on-site by up to 50 mm. Since the nominal 50 mm stroke is the maximum, you can dial the usable extend down to zero without swapping the actuator. Remember the retract end is fixed, and the stop sets end position only.

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-50S Is Used
Press Fit Tuning
Dial in the exact 0-50 mm extend contact point for seating bearings without reprogramming the machine cycle.
Variable Diverter Gate
Adjust the extend length on-site to redirect different carton sizes on a packaging line.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X50-50S the Right Cylinder?
The adjustable window shines when you need to fine-tune the extend end position on-site or want one shared spare across slight stroke variants. Mounting options include FA, LB, TC, TCM1, and TCM2. The -S magnet supports CMSE/DMSE sensors. Because the stroke here is under 300 mm, side-load guide concerns are minimal, but always keep the load axially aligned.
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 JSIJ100X50-50S FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. It uses a G1/2 port and a 33 mm adjustable air cushion at each end.
The nominal 50 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 50 mm, bringing usable extend down to zero. The retract end remains fixed. This stop only sets the end position and does not lock the load.
