The NSK 7004A5SN24TRDUMP3 is a genuine NSK high-precision angular contact ball bearing, specifically engineered for demanding machine tool spindle applications. This hybrid bearing features ceramic balls (TR) for superior high-speed performance, reduced friction, and extended service life. It has a 15-degree contact angle (A5) for high axial and radial rigidity, a durable polyamide resin cage (SN24), and is universally ground (DU) for flexible duplex mounting in O or X arrangements. With a P3 precision class and light preload (MP3), it ensures exceptional accuracy and reliability in high-speed, high-precision machinery.
