The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-100 is a genuine double acting, adjustable stroke JIS-standard air cylinder with a Ø50mm bore and 1000mm 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 is built for long-reach actuation where end-position flexibility matters. The hard-anodized aluminum extruded barrel keeps the overall body more compact than a same-bore ISO 15552 unit. It handles a safe working load of about 589 N, which translates to lifting roughly 50 kg vertically with a 2:1 safety margin. Air connects via a G1/4 port.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 900 to 1000 mm while the retract end stays fixed. You can fine-tune the endpoint without physically swapping the cylinder. This non-magnetic SKU cannot take a sensor; adding an -S variant enables CMSE/DMSE switches. Note that a plain cylinder drifts on air loss—the cushion only decelerates, so use an external rod lock for held loads.

Pushes parts down a 1000 mm conveyor lane, using the 100 mm adjuster to dial the exact reject distance without changing the actuator.
Reaches deep into storage racks to extract totes, relying on the compact JIS profile to fit tight vertical shuttle spaces.
Extends fully for raw stock clamping then shortens by 100 mm for finished parts, allowing one cylinder to handle two distinct stop points.
When sizing, the 40 mm bore offers 628 N push at 0.5 MPa, while the 63 mm bore jumps to 1559 N if you need more authority. This 50 mm model sits comfortably in the middle for medium tasks. The 100 mm adjustable window is ideal for sharing a spare across stroke variants or dialing in final end positions on-site. JSIJ mounting options include FA, LB, TC, TCM1, and TCM2. Because the 1000 mm stroke invites rod bending, always use an external guide to manage side loads.
Quick checklist
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 nominal 1000 mm stroke is the maximum. An external stop screw lets you shorten the extend stroke on-site by up to 100 mm, yielding a usable range of 900 to 1000 mm. The retract end remains fixed.
