Design considerations

Additional housing support modate the loads acting parallel to the support
When the housing is subjected to loads acting surface.
parallel to the support surface, it may be nec-
essary to pin the housing to the support sur-
face or to provide a stop to counter the load.
When loads act at angles between 60° and
120°, or when the axial loads are greater than
5% of P 180° , the housing should be pinned to
the support surface or a stop should be pro-
vided to counter the load. The dowel pins or
stop should be sufficiently strong to accom-
