SMC NCDA1B400-0400 Double Acting Pneumatic Air Cylinder

SMC NCDA1B400-0400 is a four-inch bore, four-inch stroke double-acting tie-rod pneumatic cylinder designed for NFPA-compatible mounting and up to 250 psi (1.7 MPa) maximum operating pressure. It features an anodized aluminum body with aluminum end caps, a magnetic piston for easy position sensing, and air cushions for smooth operation, all contributing to a lightweight, corrosion-resistant construction. The cylinder has a single piston rod with a 1 in diameter and a 3/4-16 thread (rod thread length 1-1/8 in), mounted via tapped holes for horizontal or vertical orientation. It weighs 7.79 lb and measures 4-1/2 in tall by 4-1/2 in wide; operating temperature range is 40 °F to 140 °F, with a minimum actuation pressure of 8 psi. Internal components include carbon steel for the piston rod and tie rods, aluminum for the end caps and piston, and an aluminum body with an anodized finish, and the unit conforms to RoHS. This NCDA1B400-0400 is a non-repairable, general-purpose tie-rod cylinder that aligns with standard NFPA dimensions, making it suitable for compact, reliable pneumatic actuation in automation applications requiring a 4 in bore and stroke with tie-rod construction.
