Loads

Dynamic loads As track rollers are not supported in a housing, the outer rings Symbols
deform, leading to an altered load distribution and bending stresses
in the outer ring C 0 basic static load rating [kN] 15
The basic load ratings listed in the product tables, page 954 , (product tables, page 954)
take into account the altered load distribution, while the maximum F r radial load [kN]
radial loads F r max (product tables) are based on the bending F r max maximum permissible dynamic
stresses radial load [kN] (product tables)
F 0r max maximum permissible static
Static loads Permissible static load is the lower value of F 0r max or C radial load [kN] (product tables)
0
(product tables). F rm minimum radial load [kN]
Where requirements for smooth running are below normal, the P equivalent dynamic bearing load
static load may exceed C , but should never exceed the maximum [kN]
0
permissible static radial load F 0r max . P 0 equivalent static bearing load [kN]
Axial loads Support rollers are intended for radial loads. However, support rollers
with lange rings can generally accommodate axial loads that can
occur because of skew or tilting. The magnitude of permissible load
depends on the internal design.
