‌FAG Cylindrical Roller Bearings are bearings with high radial load capacity and low friction coefficient, suitable for heavy loads and high speed conditions. ‌

The main features of FAG cylindrical roller bearings include:

‌High radial load capacity‌: Suitable for heavy loads and shock loads.

‌Low friction coefficient‌: Reduces friction and is suitable for high-speed rotation.

‌Structural features‌: The inner and outer rings are separable for easy installation and removal. Bearings can be divided into single-row, double-row and multi-row cylindrical roller bearings, and their designs and applications vary depending on the number of roller rows. ‌

The design differences of FAG cylindrical roller bearings are mainly reflected in the number of roller rows, the flange design of the inner and outer rings, and the design and material of the cage. These bearings can meet the application requirements of heavy radial loads and high speeds. They also have the ability to accommodate axial displacement (unless both inner and outer rings have flanges), provide high stiffness, low friction and long service life. In addition, FAG also provides sealed or split designs to suit different application needs, such as protecting rollers from contaminants, water and dust, while retaining lubricants and excluding contaminants, thereby reducing friction and extending service life.

As a pinnacle of the Schaeffler Group’s bearing technology, FAG Cylindrical Roller Bearings deliver uncompromising performance in applications demanding maximum radial load capacity, high-speed operation, and precision rigidity. Renowned for their robust design and versatility, these bearings are engineered to excel in industries ranging from wind energy and mining to machine tools and heavy transportation.
