Lubrication

Circulating oil lubrication system
When using a circulating oil lubrication sys-
tem with any SDAF housing, oil is introduced
through the inlet holes in the housing cap and
drained from one or both sides of the base.
Drains should lead downward immediately
outside of the housing to prevent oil from
accumulating in the housing. Too high an oil
level can result in higher operating tempera-
tures due to churning of the lubricant. The
drain pipes must be adequately sized and
arranged to allow oil to drain from the housing.
Additional considerations may be necessary
when using a circulating oil system. These can
include special housing seals, cross drilling the
housing sump, wet sump requirements, flow
rates, and drain hole dimensions. For more
information, contact the SKF application engi-
neering service.
