The NSK 7005CTYNSULP4 is a high-precision, single-row angular contact ball bearing designed for applications requiring high rotational accuracy and speed. It features a 15° contact angle (C) for accommodating radial and axial loads in one direction. The polyamide resin cage (TYN) allows for high-speed operation with reduced noise and friction. This bearing is universally matchable (SU), enabling it to be used in pairs (back-to-back, face-to-face, or tandem) for various mounting requirements. With a light preload (L) and P4 precision class, it is ideal for demanding applications such as machine tool spindles, high-speed motors, and precision measuring instruments.
