The NSK NAS15ALZ is a precision-engineered linear guide block designed for high-accuracy linear motion systems. Part of NSK’s NS Series, this carriage uses a four-row recirculating ball bearing mechanism to provide low-friction, high-rigidity movement under demanding dynamic and static loads.
Manufactured with tight dimensional tolerances and hardened steel raceways, the NAS15ALZ ensures stable running accuracy, excellent stiffness, and minimal deflection. The “Z” light preload classification removes internal clearance, improving both precision and repeatability in high-performance applications.
