Product Description

SKF super precision cylindrical roller bearings,double row NN series
 

Description:

SKF super-precision cylindrical roller bearings are characterized by:

• high speed capability
• high radial load carrying capacity
• high rigidity
• low friction
• 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 super-precision single row cylindrical roller bearings have a higher speed capability than double row bearings while double row bearings are more suitable for heavier loads.
