7044 CD/P4A

The 7044 CD/P4A Angular Contact Ball Bearing is a super-precision component meticulously engineered for applications demanding extreme rotational accuracy, high speed, and robust support for significant combined loads. As a single-row angular contact bearing, it is designed to manage high radial loads concurrently with heavy axial loads acting in one direction. With a substantial 220mm bore diameter, 340mm outer diameter, and a 56mm width, this bearing is built for high-performance industrial machinery.

The "CD" suffix signifies an optimized internal design, often indicating a 15-degree contact angle which enhances its axial load-carrying capacity. Crucially, the "P4A" designation denotes a super-precision class (P4), ensuring exceptionally tight tolerances, minimal runout, and outstanding rotational accuracy, making it ideal for maintaining precise shaft guidance at high speeds. These bearings are frequently mounted in pairs (such as back-to-back or face-to-face arrangements) to accommodate bidirectional axial loads or to achieve even greater rigidity and load distribution. Primarily utilized in critical applications like machine tool spindles, high-speed grinding machines, precision gearboxes, and other advanced rotating equipment, the 7044 CD/P4A delivers unparalleled performance, directly contributing to superior machining quality, reduced vibration, and enhanced productivity.
