Airtac SGCJ200-250 Adjustable Cylinder SGCJ250X450-30

Delivering 24543 N of push force at 0.5 MPa, this large-bore ISO 15552 tie-rod cylinder integrates an external adjuster that shortens the extend stroke on-site by up to 30 mm. The nominal 450 mm stroke serves as the maximum, yielding a usable 420 to 450 mm extend window while the retract end remains fixed. This allows precise end-position tuning without physically swapping the cylinder. It handles a safe working load of about 14726 N, which translates to lifting roughly 1251 kg vertically with a 2:1 margin. Four steel tie rods clamp the aluminum barrel to the covers for structural rigidity, and the G1 pneumatic port matches the 250 mm bore standard.

Dimensionally interchangeable per the ISO 15552 mounting interface, it drops directly into existing large-bore fixtures. The unit features adjustable 60 mm air cushions at both ends to decelerate heavy loads smoothly. Because this is a 250 mm bore, TPU seals are not available; instead it uses NBR packings, with a Viton H high-temperature option rated for 0 to 150 C. Note that this specific SKU lacks a magnet, meaning it cannot accept CMSG, DMSG, or EMSG magnetic sensors without upgrading to the -S variant. Furthermore, the cushion only decelerates the piston and does not hold the load on air loss, so an external rod lock or pilot-operated check valve is required for suspended loads.
