Schaeffler Group introduced the "Expanded calculation of the adjusted rating life" in 1997. This method was standardised for the first time in DIN ISO 281 Appendix 1 and has been a constituent part of the international standard ISO 281 since 2007.

However, modern, high quality FAG bearings can exceed by a considerable margin the values calculated for the basic rating life under favourable operating conditions. Ioannides and Harris have developed a further model for fatigue in rolling contact that expands on the Lundberg and Palmgren theory and gives a better description of the performance capability of modern bearings.

The term dynamic indicates that the operating condition is with the bearing rotating. This is not a variable load. carrying capacity is described in terms of the basic dynamic load rating and the basic rating life.

The calculation in accordance cannot be applied to radial needle roller bearings, axial needle roller bearings and axial cylindrical roller bearings. Combined loads are not permissible with these bearings.

The values for the recommended rating life are guide values for normal operating conditions. In addition, the tables give the operating life values that are usually achieved in practice at various mounting locations.

If high, static or shock loads occur, the raceways and rolling elements may undergo plastic deformation. This deformation limits the static load carrying capacity of the FAG rolling bearing with respect to the permissible noise level during operation of the bearing.

Belt Capacity Chart The Following conveyor belt capacity charts show tons per hour (TPH) based on material weighing 100 lbs. per cubic foot, 20 material surcharge angle with three equal length rolls on troughing idlers. CAPACITY (TPH) = .03 x Belt Speed (FPM) x material weight (lb. per cu. ft.) x load cross section (sq. ft.)

Belt Tension Calculator First, the Effective Belt Tension (TE) must be calculated. TE is the sum of the tension required to move the empty belt (TC), the tension required to move the load horizontally (TL), and the tension required to lift the load (TH). Example 1. TE = TC + TL + TH TC = F1 x L x CW
