The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X150-100 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.
Delivering 982 N of push force at 0.5 MPa, this 50 mm bore JIS profile cylinder features a hard-anodized aluminum barrel that is noticeably shorter than a same-bore ISO 15552 unit. The external adjuster allows you to shorten the extend stroke on-site by up to 100 mm, yielding a usable extend range of 50 to 150 mm while the retract end remains fixed. This mechanism lets you fine-tune the end position without physically swapping the cylinder.
In practical terms it handles about 589 N of real work, which translates to safely lifting roughly 50 kg vertically with a 2:1 margin. The unit operates on a G1/4 port, runs at 30-800 mm/s, and includes adjustable air cushions of 20.5 mm at both ends. Note that this specific SKU lacks a magnet and cannot accept CMSE/DMSE sensors; for that capability you need the -S variant. Furthermore, the cushions only decelerate the load near stroke end, so an external rod lock or pilot-operated check valve is required to hold a load securely on air loss.

Dial in the exact extend distance from 50 to 150 mm on a packaging line without changing out the entire actuator.
Fine-tune the clamping endpoint on a machining fixture to accommodate different part heights on the fly.
Set precise downward travel limits for light pressing tasks where the 982 N thrust is sufficient.
When sizing this model, the neighboring 40 mm bore offers 628 N of push at 0.5 MPa for lighter duties, while the 63 mm bore steps up to 1559 N if your application demands more thrust. The adjustable stroke window is highly beneficial when you need on-site end-position tuning or want to standardize a shared spare across multiple stroke variants. JSIJ mounting options include Basic, FA, LB, TC, TCM1, and TCM2 styles. Because this is a non-magnetized SKU, it cannot host position sensors. For any stroke length of 300 mm or greater, always use a guide rail to prevent excessive side-loading on the piston rod.
Quick checklist
This 50 mm bore cylinder uses a G1/4 port and generates 982 N push / 825 N pull at 0.5 MPa, 1374 N push / 1154 N pull at 0.7 MPa, with a theoretical maximum of 200 kgf at 1.0 MPa.
The nominal 150 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, giving a usable extend range of 50 to 150 mm. The retract end is fixed, and the stop sets position only, not a load lock.
