Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-50S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-50S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 300mm 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 JSIJ50X300-50S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features an external adjuster that lets you shorten the extend stroke on-site by up to 50 mm. The nominal 300 mm stroke remains the maximum travel, while the retract end stays fixed. This on-site tuning is ideal for dialing in exact end positions without swapping the whole unit, and the built-in -S magnet allows CMSE/DMSE sensors to drop directly into the side grooves for position detection.
Built with an extruded hard-anodized aluminum barrel, the body is notably shorter and more compact than an equivalent ISO 15552 cylinder of the same bore. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 margin. The unit operates on a G1/4 port, runs at speeds of 30-800 mm/s, and uses adjustable air cushions at both ends to decelerate the piston smoothly.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-50S Is Used
Conveyor Diverter Tuning
Fine-tune the extend stop by up to 50 mm on-site to perfectly align a diverter gate without machining new mounts.
Vertical Lift Stops
Lifts approximately 50 kg vertically using the 982 N push force, with adjustable end positions for varying package heights.
Press Clamping Adjustment
Dial in the exact clamping reach on a 300 mm stroke press, compensating for material thickness variations on the fly.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X300-50S the Right Cylinder?
When sizing this actuator, the 50 mm bore provides a solid middle ground, stepping up from the 40 mm bore's 628 N push force, or stepping down from the 63 mm bore's 1559 N if you need a lighter footprint. The -50 mm adjustable window is particularly useful when you need a shared spare across slightly different stroke variants or precise end-position tuning on the machine. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. Because the stroke is 300 mm, always use external guides to prevent rod bending and account for side loads. The -S variant supports CMSE/DMSE sensors, whereas a standard 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 JSIJ32~50 Adjustable Cylinder JSIJ50X300-50S FAQ
At 0.5 MPa it delivers 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. This 50 mm bore unit uses a G1/4 port.
An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, giving a usable extend range of 250 to 300 mm. The nominal 300 mm stroke is the maximum travel, and the retract end is fixed. This mechanism only sets the end position; it is not a load lock.
