Single Row Cylindrical Roller BearingsNU348M Bearing

Single row cylindrical roller bearings are a type of bearing that is designed to support heavy radial loads and high speeds. They are commonly used in industries such as machine tools, paper mills, and electric motors where high precision and reliability are crucial.

These bearings consist of a cylindrical roller and raceway, and are available in a variety of sizes and designs. They can be either integral or separable, and can be designed with different cage materials, such as steel, brass, and polyamide.

One of the main advantages of single row cylindrical roller bearings is their ability to accommodate axial loads in one direction. This makes them particularly useful in applications where axial loads are present and a certain degree of rigidity is required.


Single Row Cylindrical Roller Bearings NU348M is a high-quality bearing that is designed for use in heavy-duty industrial applications. This bearing is manufactured to provide superior durability and reliability, making it an ideal solution for challenging environments.

The NU348M bearing features a single row of cylindrical rollers, which helps to distribute the load evenly and reduce friction during operation. This design also promotes high-speed performance and helps to minimize wear and tear on the bearing.

Constructed from premium-grade materials, the NU348M bearing boasts exceptional strength and resistance to corrosion, ensuring dependable operation even in harsh conditions. It is engineered to withstand high radial loads, making it ideal for use in heavy equipment like cranes, construction machinery, and mining equipment.

In addition to its robust construction, the NU348M bearing also features advanced sealing technology that helps to prevent contamination and keep the bearing lubricated. This innovative sealing system helps to extend the lifespan of the bearing and reduce maintenance costs.
