Standard housing design

Features and benefits Fig. 4
SAF and SAW housings share some of the Individually marked cap and base
following features and benefits:
Simple mounting and dismounting
To simplify mounting and make alignment more
accurate, the feet of SAF and SAW housings
have a flat, square design.
To make it easier to separate the cap
and base, pry slots are cast into the housing.
Smaller sizes have sphered dowel pins to
further ease cap removal.
Mounting instructions are supplied with
each housing.

Caps and bases individually marked
The housing base and cap are matched during
manufacture and are not interchangeable with
the caps and bases of other housings. To help
avoid mismatch, each cap and base are num-
bered († fig. 4). 8
Grease or oil lubrication
These housings are designed to accommodate
both grease and oil lubrication. The sump in
the housing base acts as a reservoir to provide
an adequate quantity of grease or oil.

Housing material
SAF and SAW housings are made of grey cast
iron.
Paint, corrosion protection
SAF and SAW pillow block housings are painted
blue (RAL 5001) using a water based alkyd/
acryl paint. The paint protects the housing in
accordance with ISO 12944-2, corrosivity cat-
egory C2 (i.e. exterior atmospheres with low
level of pollution, interior atmospheres where
condensation may occur). The paint is not
affected by most lubricating or engine oils,
cutting fluids or alkalescent washing chem-
icals. Housings can be repainted with most
water or solvent based 1- or 2-component
paints.
Special paints or preservatives can be sup-
plied on request. Unpainted surfaces are pro-
tected by a solventless rust inhibitor.
