The NSK 7011A5TYNSULP4 is a high-precision, single-row angular contact ball bearing designed for applications requiring high rotational accuracy and speed. Engineered for universal matching (SU), this bearing can be mounted in various arrangements (duplex, triplex, etc.) to meet specific rigidity and load requirements. It features a 25-degree contact angle (A5) for accommodating both radial and axial loads, a light preload (L) for low friction, and a P4 precision class (equivalent to ABEC 7) for superior running accuracy. The polyamide resin cage (TYN) ensures excellent performance at high speeds with reduced noise and heat generation, making it an ideal choice for machine tool spindles, measuring instruments, and other precision machinery.
