SMC Corporation NCDGBN25-0900-B54L Single Acting Pneumatic Cylinder

SMC NCDGBN25-0900-B54L is a compact single-acting pneumatic cylinder with a single rod and spring-return, engineered to extend when air pressure is applied and to retract automatically via an internal return spring. The model designation includes BN25, aligning with a 25 mm bore size and a round-body actuator profile that fits tight installations while delivering dependable linear motion. This configuration is optimized for straightforward, repeatable extension cycles in automated equipment where a simple, maintenance-friendly reset is desirable after each actuation. Because the cylinder uses air pressure to extend and a spring to retract, it can reduce plumbing complexity and energy use for applications that do not require retracting pressure on the return stroke. For exact stroke length, mounting options, port configuration, and any integrated sensing possibilities, consult the official SMC catalog entry for NCDGBN25-0900-B54L to verify compatibility with your equipment’s envelope and cycle requirements. When selecting this actuator, consider the available space for installation, the required extension stroke, and how a spring-return mechanism aligns with your control logic and safety requirements in a compact automation setup.
