Precision Cylindrical Roller Bearings

Standard and Precision Cylindrical Roller bearings utilize a cylindrical roller whereas a ball bearing utilizes a spherical ball as the main rolling element. Cylindrical roller bearings may have a single or multiple row rolling element set. In contrast to the ball, the roller has a larger contact area perpendicular to the roller axis. Cylindrical rollers can transmit higher forces will have greater rigidity and will be smaller due to the rolling element diameters under the same load as a ball bearing.

Standard Cylindrical roller bearings are used in applications like industrial gearboxes, gear-boxes in wind turbines or machines for mining equipment. In these applications, high load carry capacity is particularly important. 

Precision Cylindrical Roller bearings

SKF and FAG  super-precision cylindrical roller bearings are characterized by higher speed capability and greater radial load carrying capacity. They will have high rigidity, low friction, and a low cross-sectional height.

These bearings are therefore particularly well suited for machine tool spindles where the bearing arrangement must accommodate heavy radial loads and high speeds while providing a high degree of stiffness.

SKF and FAG  super-precision single row cylindrical roller bearings have a higher speed capability than double row bearings which are more suitable for heavier loads.

Precision Cylindrical Roller bearings will perform at higher speeds due to tighter tolerances, higher precision grades, and the use of ceramic rolling elements.
