Product Description
The SMC NCQ2B40-25D is a compact pneumatic cylinder from the NCQ2/CQ2 Series, featuring a 40 mm bore and 25 mm stroke in a space-saving, through-hole mountable body. It operates as a double-acting, single-rod cylinder with a standard body and standard piston rod, designed for North American RC/M port threading. This is a legacy product superseded by the NCQ2B40-25DZ, and is valued for its lightweight aluminum alloy construction and versatile auto-switch groove compatibility.
