Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 450mm 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 JSIJ50X450-30
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore pneumatic actuator features a hard-anodized aluminum profile barrel that is noticeably shorter than a same-bore ISO 15552 cylinder. The G1/4 port feeds a double-acting single-rod mechanism rated for 30-800 mm/s speeds, while adjustable air cushions of 20.5 mm at each end absorb end-of-stroke impact.
An external stop screw provides a 30 mm on-site extend-shortening window, letting you fine-tune the usable forward travel down to 420 mm without swapping the cylinder. Factoring in a realistic 60 percent safety margin, it handles about 589 N of actual work, which translates to lifting roughly 50 kg vertically. Because this specific SKU lacks the -S magnet option, it cannot accept CMSE or DMSE position sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-30 Is Used
Transfer Push-Off Tuning
Dial in the exact push-off distance on a conveyor diverter by trimming the 450 mm extend stroke up to 30 mm on-site to match varying package sizes.
Pallet Stop Adjustment
Fine-tune the stopping point for pallets on a packaging line, using the external adjuster to compensate for wear without changing the actuator.
Vertical Press Positioning
Set a precise lower end position for a light pressing task, safely lowering the rod to a custom 420 mm stroke while relying on the cushions for deceleration.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X450-30 the Right Cylinder?
When sizing this model, the 63 mm bore offers a substantial jump to 1559 N push at 0.5 MPa, whereas dropping to a 40 mm bore limits you to 628 N. The 30 mm adjustable window is highly useful for synchronizing end positions across multiple stations or sharing a single spare unit across slightly different stroke variants. You can mount it via FA, LB, TC, TCM1, or TCM2 brackets. Since the 450 mm stroke creates leverage, always use external guides to prevent rod bending and side-load damage. Remember that the stop screw sets position only; for load holding on air loss, install an external rod lock or pilot-operated check valve.
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 JSIJ50X450-30 FAQ
This 50 mm bore cylinder uses a G1/4 air port and an M18x1.5 rod thread. It generates 982 N push and 825 N pull at 0.5 MPa, increasing to 1374 N push and 1154 N pull at 0.7 MPa. The theoretical maximum force is 200 kgf at 1.0 MPa.
The -30 indicates a 30 mm external adjustment window. The nominal 450 mm stroke is the maximum, but turning the external stop screw lets you shorten the extend stroke on-site down to 420 mm. The retract end remains fixed, and this mechanism only sets the end position rather than locking the load.
