The NSK 7009CTYNP4 is a high-precision, single-row angular contact ball bearing designed for applications demanding high accuracy and rotational speed. It features a 15° contact angle (C) which makes it suitable for carrying axial loads in one direction as well as radial loads. The TYN designation indicates a robust, ball-guided polyamide resin cage, which offers excellent performance at high speeds with low heat generation. Manufactured to a P4 precision class (ISO Class 4), this bearing provides superior running accuracy, making it an ideal choice for machine tool spindles, high-speed pumps, and other precision rotating machinery.
