TERMINOLOGY:
n = Working speed
L10h = Bearing service life, in h
C = Rated dynamic load of bearing
max P = Radial load admissible on bearing for L10h and n
max Fr = Maximum radial force on pulley
(*) The maximum radial force on the pulley is lower than the values of the selected set of bearings
Ball bearings with ZZ blanking plates are greased for their entire service life.
