Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 600mm 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 JSIJ50X600-30S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder saves valuable machine space because its hard-anodized extruded aluminum body is shorter than a same-bore ISO 15552 unit. The -30 code means an external adjuster can trim the extend stroke by up to 30 mm on site, letting you fine-tune the 600 mm end position without swapping the actuator. It feeds through a G1/4 port and carries an M18x1.5 rod thread.
Because the -S suffix equips the piston with a magnet, the side grooves accept CMSE or DMSE reed and electronic switches for exact positioning. In practice it handles a safe working load of roughly 589 N, which means you can lift about 50 kg vertically with a 2:1 safety margin. The retract end remains fixed, while the 20.5 mm adjustable air cushions at both ends absorb kinetic energy smoothly.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30S Is Used
Transfer Line Diverter
Fine-tune the 600 mm extend reach by up to 30 mm on site to match varying pallet widths without changing the cylinder.
Vertical Carton Lift
Lifts roughly 50 kg of packaged goods vertically using the 982 N push force at 0.5 MPa with a safe 2:1 margin.
Press Tool Positioning
Uses the external stop screw to set a precise 570 mm extended working position for delicate assembly operations.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X600-30S the Right Cylinder?
When sizing this actuator, a 40 mm bore gives 628 N of push at 0.5 MPa for lighter duties, whereas stepping up to a 63 mm bore yields 1559 N for heavier loads. The adjustable window shines when you need to dial in a precise end position across multiple stations or want a single spare part that covers slight stroke variations. You can mount it using the FA, LB, TC, TCM1, or TCM2 brackets. Since this is a 600 mm stroke, always support the load with an external guide rail to prevent rod bending and side-load wear. The built-in magnet works seamlessly with CMSE/DMSE sensors.
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 JSIJ50X600-30S FAQ
At 0.5 MPa it pushes 982 N and pulls 825 N. At 0.7 MPa it pushes 1374 N and pulls 1154 N. The theoretical maximum force is 200 kgf at 1.0 MPa. The air port size is G1/4.
The nominal 600 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on site, giving a usable range of 570 to 600 mm. The retract end is fixed, and the adjuster sets the end position rather than locking the load.
