  • 14 Rolling element bearings for rotary motion

    2008-3-24 · • Many rolling element bearings can support radial and axial loads. • In order to size a rotary motion bearing, an equivalent radial load Fe must be found: Kw: rotation factor = 1 for rotating inner ring and 2 for a rotating outer ring. Kr: radial load factor = 1 (almost always). KA: axial load factor. ¾KA=1.4 for radial contact ball bearing.
