Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-30S
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-30S is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 900mm 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 JSIJ50X900-30S
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore unit handles about 589 N of real work, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. The hard-anodized aluminium profile barrel keeps the total length shorter than a same-bore ISO 15552 cylinder, and the G1/4 air port matches the standard JIS sizing.
The external stop screw lets you trim the extend stroke on-site by up to 30 mm, giving a usable range of 870 to 900 mm without swapping the actuator. Because this is an -S SKU, the built-in piston magnet works directly with CMSE/DMSE switches in the side grooves for position feedback. Remember that the cushion only decelerates the load; use an external rod lock or pilot-operated check valve if you need to hold position against a drop in air pressure.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-30S Is Used
Long-Reach Diverting
Pushes packages across a wide sorting lane, using the 30 mm extend adjuster to dial in the exact contact point without repositioning the cylinder.
Vertical Material Lift
Raises a 50 kg tote to a raised platform, relying on external linear guides to support the 900 mm stroke and prevent rod deflection.
Adjustable End Stop Press
Extends a forming tool to a precise depth, trimming the stroke from 900 mm down to 870 mm on-site to accommodate different material thicknesses.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X900-30S the Right Cylinder?
When sizing this actuator, the 63 mm bore steps up to 1559 N push at 0.5 MPa, while the 40 mm bore drops to 628 N, so the 50 mm bore is the right middle ground for moderate loads. The 30 mm adjuster is ideal for sharing a single spare across multiple stroke variants or fine-tuning the end position on-site. Mounting options include FA, LB, TC, TCM1, and TCM2 brackets. At a 900 mm stroke, you must support the load with external guides to prevent rod bending and side-load damage. The -S magnet supports CMSE/DMSE sensors, whereas a non-S SKU cannot take a sensor at all.
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 JSIJ50X900-30S 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. This 50 mm bore actuator uses a G1/4 air port and features a 20 mm piston rod with an M18x1.5 rod-end thread.
The nominal stroke is 900 mm, which is the maximum extend length. The external adjuster lets you shorten the extend stroke on-site by up to 30 mm, giving a usable range of 870 to 900 mm. The retract end remains fixed. This mechanism sets the end position and does not lock the load.
