Notes 1) Negative value indicates effective center within the width of the inner ring. 2) ISO calculation based on one million revolutions for L10 life. 3) Timken Company life calculations based on 90 million revolutions for L10 life. C90 is radial load component force; Ca90 is axial component. 4) For synthetic high speed grease; other methods may further improve speed by as much as 60% or more. 5) Other sizes not shown may be possible. Call for availability. *Tighter tolerances are possible on any of the part numbers shown for higher precision requirements.
