The determined loads must be multiplied with a factor f_stat allocated to the application. The product F_a' or M_k' must be below the static critical load curve of the selected bearing.

With regard to radial loads in load combinations

F_a = axial load
F_r = radial load
M_k = tilting moment

the reference loads for the "static" bearing selection from the KD 210 and KD 600 type series are computed as follows according to I or II:

F_a' = (F_a + 5.046 · F_r) · f_stat
M_k' = M_k · f_stat

F_a' = (1.225 · F_a + 2.676 · F_r) · f_stat
M_k' = 1.225 · M_k · f_stat

I and II apply analogously to types 13 and 21, but without the factor f_stat.
A bearing is statically suitable if one of the two load combinations (I or II) is below the static critical load curve.

The reference load for the RD 800 type series is:

F_a' = (F_a + 2.05 · F_r) · f_stat
M_k' = M_k · f_stat

The bearing is statically suitable if one of the two load combinations (I or II) is below the static critical load curve.

For the KD 320 and RD 700 type series, radial loads F_r ≤ 10 % of the axial load can be neglected in selecting bearings by critical load curves.

If the radial load is F_r > 10 % of the axial load, the supporting angle must be taken into account. The respective calculation will then be done by us.

In the RD 900 type series, radial loads have no influence on the critical load curve.
