Symbols
F a /F r ≤ e
† P = F r
F a /F r > e
† P = 0,92 F r + Y F a
F a must not exceed 0,5 F r .
F a /F r ≤ 0,15
† P = F r
F a /F r > 0,15
† P = 0,92 F r + 0,4 F a
F a must not exceed 0,25 F r .
d m = bearing mean diameter
[mm]
= 0,5 (d + D)
e
= limiting value
(† table 7, page 593)
F a = axial load [kN]
F r = radial load [kN]
F rm = minimum radial load
[kN]
k r = minimum load factor
(† product tables and
table 6, page 593)
n = rotational speed [r/min]
n r = reference speed [r/min]
(† product tables)
For sealed double row
full complement
bearings with seals
removed and oil
lubrication: use 1,3
times the limiting speed
P = equivalent dynamic
bearing load [kN]
P 0 = equivalent static
Y
bearing load [kN]
= axial load factor
