Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 200mm stroke, G1/4 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 JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder integrates an external adjuster that lets you shorten the extend stroke on-site by up to 100 mm. The nominal 200 mm stroke represents the maximum travel, meaning your usable extend range is 100-200 mm while the retract end remains fixed. This on-site tuning allows precise end-position setting without physically swapping the cylinder, and the hard-anodized aluminum extruded barrel keeps the total envelope shorter than a same-bore ISO 15552 unit.
Equipped with a G1/4 port and an M18x1.5 rod thread, the unit handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. The -S suffix indicates a built-in piston magnet for CMSE/DMSE switches that drop directly into the side sensor grooves. Note that a plain cylinder does not hold load on air loss; the 20.5 mm adjustable air cushions only decelerate the piston near the ends, so fit an external rod lock or pilot-operated check valve if you need strict load holding.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S Is Used
Press Stroke Tuning
Dial in the exact 100 to 200 mm extend reach on a light stamping or pressing station without machining new hard stops.
Transfer Gate Adjustment
Vary the extend length on a diverter gate to accommodate different package widths on the fly.
Vertical Lifting Jig
Lift a 50 kg fixture using the 0.5 MPa thrust, relying on the external adjuster to set the precise raise height.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S the Right Cylinder?
When sizing this 50 mm bore, stepping down to a 40 mm bore drops the 0.5 MPa push force to 628 N, while stepping up to a 63 mm bore raises it to 1559 N. The adjustable stroke window is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position during machine commissioning. Mounting options include Basic, FA, LB, TC, TCM1, and TCM2 brackets. Because this is an -S model, it arrives ready for CMSE/DMSE sensors. For any stroke at or above 300 mm, always guide the load to prevent side-load damage to the front cover and piston rod.
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 JSIJ32~50 Adjustable Cylinder JSIJ50X200-100S FAQ
At 0.5 MPa it provides 982 N push and 825 N pull. At 0.7 MPa it provides 1374 N push and 1154 N pull. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4.
The external stop screw lets you shorten the extend stroke on-site by up to 100 mm. The nominal 200 mm stroke is the maximum, so the usable extend range is 100-200 mm. The retract end is fixed, and the stop sets end position rather than locking the load.
