Housing material
All housings used for SKF inch roller bearing
units are made of grey cast iron.

Paint, corrosion protection
The housings are painted blue (RAL 5007)
using a water based alkyd/acryl paint. The
paint protects the housing in accordance with Labyrinth seal
ISO 12944-2, corrosivity category C2 (i.e. (for SKF ConCentra)
exterior atmospheres with low level of pollu-
tion, interior atmospheres where condensa-
tion may occur). The paint is not affected by
most lubricating or engine oils, cutting fluids
or alkalescent washing chemicals. Housings
can be repainted with most water or solvent
based 1- or 2-component paints.
Unpainted surfaces are protected by a sol-
ventless rust inhibitor. Labyrinth seal
(for collar-mount)
