When a load in any direction other than the direction of basic dynamic load rating or a complex load is applied, calculate the dynamic equivalent load to calculate the rating life.J7■Static Equivalent LoadThe direction of basic static load rating of Crossed Roller Bearing is the radial direction. When a load in any direction other than the direction of basic static load rating or a complex load is applied, calculate the static equivalent load to calculate the static safety fac-tor.P0r=Fr + 2M+0.44 Fa …………………(2) Dpwwhere, P0r : Static equivalent radial load, N Fr : Radial load, N Fa : Axial load, N M Dpw : itch circle diameter of roller set, mm: Moment, N -mm 2Dpw≒ d+D( )Remarks he static equivalent load is calculated differently for LCRB.
