SKF can provide a portfolio of different calculation methods to optimize bearing selection for any kind of application. Basic calculation principles are mentioned in this chapter, to give an overview of state of the art methods that can be used for axlebox bearing calculation and more advanced ...
Bearing Selection In many cases involving bearing selection during the initial design of a machine, obtaining a satisfactory rating life is the prime consideration. The shaft size is usually decided first, based on allowable working stress and deflection. This establishes the bearing bores. Fortunately...
The invention discloses a calculation of the fit between a rolling bearing and a shell and structure selection. According to gap variation difference which is produced according to the expansion coefficient of different matching materials under the natural assembling state, the normal working state and...

Romax Adjusted -extends the ISO 281 calculation to include effects of misalignment. Romax Advanced -uses a much more accurate model for contact stress than the previous two methods. DIN ISO 281 Supplement 4 -follows on from the original ISO method, but also makes use of the Advanced contact ...
Window selection can be guided by the use of spectral kurtosis, or by selecting part the spectrum where the bearing under analysis would have a resonant response. Appendix: 1 - Example of Spectral Kurtosis Algorithm 2 - Example of Welch’s Method for the Calculation of the Spectrum 3 - ...
Matching selection The choice of cooperation is generally carried out in accordance with the following principles.The load on each ring can be divided into rotating load, stationary load or non directional load, depending on the load direction, the nature of the bearing and the rotation of the ...
Wild-type IL-2 has a specific activity of 15 × 106 IU mg−1(ref.48). Thus, based on the molecular weight of 15.5 kDa a 4.4 μM solution is equivalent to 1,000 IU μl−1. Based on this calculation all cytokines and construct were administered on a molar basis ...
kN X = radial load factor for the bearing Y = axial load factor for the bearing e = limiting value for Fa/Fr and with reference to tables 2 and 3 C0= basic static load rating, kN f0 = bearing-dependent calculation factor The limiting value e and the load factors X and Y required ...
to the present invention, the circuit 110 calculates the range in accordance with the equation: ##EQU19## where θ will be either θA1or θB1. The signal T1is supplied along the conductor labelled T to another input terminal of the circuit 110 in order to implement the calculation. ...
