Designs and variants

The most commonly used NoWear coated bearings have only the rolling elements coated (designation suffix L5DA). They are recommended for applications where the bearing load is light to normal, or where vibration and oscillating movements occur.
NoWear coated bearings that have the inner ring raceway(s) and rolling elements coated (designation suffix L7DA) are recommended for any of the following operating conditions:
  • abrasive contaminants that can cause premature wear
  • heavy loads
  • unusual lubrication conditions such as bearings lubricated by the process media
Most SKF rolling bearings can be supplied as NoWear coated bearings. For variants not listed in table 1 contact the SKF application engineering service.


Refer to Cages in the relevant product section of the standard bearing.
