The AirTAC Airtac JSIJ32~50 Adjustable Cylinder JSIJ50X1000-75 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 brings compact power to long-stroke tasks. Its extruded hard-anodized aluminum barrel leaves out external tie rods, making the overall body shorter and more compact than a same-bore ISO 15552 unit. The G1/4 port feeds a double-acting single-rod design rated for 30-800 mm/s speeds.
A built-in external adjuster lets you shorten the extend stroke on-site by up to 75 mm, meaning the usable forward travel spans 925 to 1000 mm while the retract end stays fixed. This allows fine end-position tuning without swapping the cylinder. In practical terms it handles about 589 N of safe working load, or roughly 50 kg lifted vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take CMSE/DMSE sensors.

Pushes parts off a conveyor over a 1000 mm reach, using the 75 mm adjuster to dial in the exact eject position without moving the cylinder mount.
Actuates a long diverting arm across a wide sorting lane, trimming the extend stroke by 75 mm to accommodate varying package sizes on site.
Lowers a light fixture platform, using the adjustable stop to set a precise lower resting height while relying on external guides for the long rod.
When sizing this unit, the 63 mm bore offers a substantial step up to 1559 N push at 0.5 MPa, while the 40 mm bore drops to 628 N. The adjustable stroke is ideal when you need a shared spare across stroke variants or precise on-site end-position tuning. Mounting options include FA, LB, TC, TCM1, and TCM2. Because the stroke is 1000 mm, always use an external guide to prevent rod bending and manage side loads. As a non-magnetized SKU, it cannot support position sensing.
Quick checklist
It provides 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 max of 200 kgf at 1.0 MPa. The air port is G1/4 and the rod-end thread is M18x1.5.
The external stop screw lets you shorten the extend stroke on-site by up to 75 mm, giving a usable forward travel of 925 to 1000 mm. The nominal 1000 mm stroke is the maximum, and the retract end remains fixed. This mechanism sets the end position but does not lock the load.
