As track rollers are not supported in a housing, the outer rings deform, leading to an altered load distribution and bending stresses in the outer ring.
The basic load ratings listed in the product tables take into account the altered load distribution, while the maximum permissible radial loads Fr max (→ product tables) are based on the bending stresses.
Permissible static load is the lower value of F0r max or C0 (→ product tables).
Where requirements for smooth running are below normal, the static load may exceed C0, but should never exceed the maximum permissible static radial load F0r max.
|Axial loads||Support rollers are intended for radial loads. However, support rollers with flange rings can generally accommodate axial loads that can occur due to skew or tilting. The magnitude of permissible load depends on the internal design.|
