Bearing static load, bearing in the following situations, should use basic C0 rated static load to calculate: low speed (n < 10 r/min) slowly reciprocating swing, in the long time under the action of static load, for rotation (under dynamic stress)

 
Bearing static load, bearing in the following situations, should use basic C0 rated static load to calculate: low speed (n < 10 r/min) slowly reciprocating swing, in the long time under the action of static load, for rotation (under dynamic stress) or skf bearings supplier http://www.tapered-roller-bearings.net/ under stationary state, only the role of the load in a short time, also must check the relevant safety factor, including the impact load and maximum load.Basic rated static load ISO 76:1981 standard, the equivalent of the heaviest load to the center of the rolling element and raceway contact, the contact stress calculation: automatic self-aligning ball bearing for 4600 mpa all other ball bearing is 4200 mpa all roller bearings is 4000 mpa under this stress can lead to permanent deformation of rolling element and raceway, approximately 0.0001 the diameter of the roller.To radial bearing load for pure radial load,For thrust bearing, the role is in the center of the bearing axial load.Calculation of the bearing static load: refers to the calculation of the static load safety factor, defined as: s0 = C0 / P0 type: C0 = basic static load rating, KN P0 = equivalent static load, KN s0 = safety coefficient to calculate the equivalent static load, static load should be the maximum load generation into the type that may occur.Bearing the basic dynamic load rating C ACTS on the dynamic load under the dynamic stress of the bearing, the rotation of the bearing under the load.Its expression shown to ISO 281:281 basic rated life when 1000000 revolutions of bearing the load.The size of the load and the direction is assumed constant.For radial bearings, the load is pure radial load, for thrust bearing, is the effect of axial load in the center of the bearing.Is defined as the rolling bearing life, on one of the rolling element bearing ring or showed signs of metal fatigue flake (or break) for the first time, before the bearings can achieve revolution to a certain speed of working hours;Practice has proved that on the surface of the same bearing under the condition of the same work, still can achieve different life.
