Overview of SKF bearing housings

Housing materials
SKF housings are typically made of either
grey cast iron or spheroidal graphite cast iron.
For information about the material options
available for a particular housing type, refer
to tables 1 to 4, starting on page 30, or the
relevant product chapter.
Grey cast iron
Grey cast iron is the standard material for
most SKF housings and is sufficient for the
majority of applications. It is characterized by
high strength, good damping capability and
good thermal conductivity.

Spheroidal graphite cast iron
Spheroidal graphite cast iron contains graphite
nodules, making it ductile. It therefore provides
a higher degree of strength and toughness
than grey cast iron. On average, housings
made of spheroidal graphite cast iron can
withstand 1,8 times heavier loads compared
to housings made of grey cast iron.
