NU 1052 M

The NU 1052 M is a single-row cylindrical roller bearing engineered for applications that demand high radial load capacity and high-speed performance. Its defining characteristic is the "NU" design, which features two integral flanges on the outer ring and a smooth, flangeless inner ring. This configuration allows the inner and outer rings to be separated, which simplifies the mounting and dismounting process. A key feature of this model is its solid machined brass cage, identified by the "M" designation. This robust cage provides excellent roller guidance and stability, significantly outperforming standard pressed steel cages, especially under conditions of rapid acceleration, high vibration, and shock loads. The combination of its internal geometry and premium cage material makes the NU 1052 M a durable solution for heavy-duty industrial machinery.

The primary advantage of the NU 1052 M bearing is its ability to function as an effective non-locating or "free end" bearing. Because the inner ring has no flanges, it can move axially in either direction relative to the outer ring. This feature is critical for accommodating thermal expansion and contraction of the shaft without inducing internal stress, thereby preventing premature bearing failure. Its line contact roller design provides a high degree of stiffness and allows it to support heavy radial forces, making it ideal for applications such as industrial gearboxes, electric motors, pumps, and construction machinery. The enhanced strength of the machined brass cage ensures long-term operational reliability, reducing maintenance downtime and contributing to a lower total cost of ownership in demanding environments.
