WTF Bearings


Bearing life extended by threefold under conditions of water infiltration and power debris (iron oxide) contamination.


1. Crack generation is restricted through the use ultrahigh cleanliness technology for the bearing steel as a measure against water infiltration.

2. Chemical components of the bearing steel have been optimized in order to strengthen the grain boundary as a measure against cracks generating along the grain boundary.

3. TF technology has been applied to the bearing steel in order to enhance service life under conditions of contaminated lubrication.
