  • Bearing Preload | National Precision Bearings

    Left image: A bearing with no play, or an interference fit has all rolling elements loaded, wears and heats up excessively. Center image: A bearing with standard play in the free state has low rigidity, and rolling elements can slide or skid instead of rotating. Right image: A standard bearing with proper preload applied will provide system rigidity, reduced vibration, and optimal bearing life.

  • Do you know the method of tapered roller bearing preload?

    Spherical thrust roller bearings sometimes suffer from scuffing, smearing, or other defects due to sliding which occurs between the roller and raceway surface in operation. To eliminate such sliding, it is necessary to mount the bearing without clearance, and apply an axial load (preload) larger than the minimum necessary axial load.
