Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-30
The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-30 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 150mm 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 JSIJ50X150-30
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder brings on-site extend-stroke flexibility to mid-range pneumatic setups. The hard-anodized aluminium barrel keeps the overall body shorter and more compact than a same-bore ISO 15552 unit. A G1/4 port feeds the double-acting single-rod piston, which drives at 30-800 mm/s across a 150 mm maximum travel.
The external -30 adjuster lets you shorten the extend stroke down to 120 mm without changing the cylinder itself, perfect for fine-tuning the end position after mounting. The retract end remains fixed, and the 20.5 mm adjustable air cushions at both ends purely decelerate the piston rather than holding the load. In practical terms it handles about 589 N of real work safely, which means lifting roughly 50 kg vertically with a 2:1 margin. Note this specific SKU lacks a magnet, so it cannot take CMSE or DMSE sensors.

Where the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-30 Is Used
Clamp Stroke Trimming
Dial in the exact clamping depth on machining fixtures by using the 30 mm extend window to shorten the 150 mm stroke, avoiding over-travel on delicate parts.
Transfer Stopper Tuning
Fine-tune the stopping position of varying-size cartons on a packaging line by adjusting the extend end point on-site without swapping the cylinder.
Shared Spare Inventory
Keep one cylinder as a universal spare for 120 mm to 150 mm stroke machines, adjusting the external stop screw to match the required travel during installation.
Is the Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-30 the Right Cylinder?
For sizing, the neighbouring 40 mm bore gives 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N, so the 50 mm sits right in the middle for 982 N loads. The adjustable -30 mm window is highly useful when you need to share one spare cylinder across several stroke variants or dial in a precise end position on the machine. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2. Because this is a no-magnet SKU, you cannot fit CMSE/DMSE switches; order an -S variant if you need position sensing. For any stroke at or over 300 mm, always guide the load to prevent side-load damage to the rod seals.
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 JSIJ50X150-30 FAQ
This 50 mm bore cylinder uses a G1/4 port. It delivers 982 N push and 825 N pull at 0.5 MPa, 1374 N push and 1154 N pull at 0.7 MPa, with a theoretical maximum force of 200 kgf at 1.0 MPa.
The nominal 150 mm stroke is the maximum. The external adjuster lets you shorten the extend stroke by up to 30 mm on-site, giving a usable extend range of 120-150 mm. The retract end is fixed, and this stop mechanism only sets the end position; it does not lock the load on air loss.
