Features and benefits Fig. 3
Standard SBD plummer block housings and Narrow width
THD take-up housings share some of the fol-
lowing features:

Stiff housing
Non-split housings provide a high degree of
stiffness and can accommodate heavy radial
loads in all directions.

Narrow width
SBD plummer block housings and THD take-
up housings are narrow and can be used
where space is limited († fig. 3).

Machined base ends
SBD housings have machined base ends to
make alignment easier and provide good
contact with stops when stops are used to Fig. 4
accommodate loads parallel to the support Machined base ends
surface († fig. 4).
Eye bolts
With the exception of the smallest housing
(SBD 2213) all SBD plummer block housings
have an eye bolt for safe and easy handling.

Housing material
Standard SBD plummer block housings and
THD take-up housing bodies are made of
spheroidal graphite cast iron (series designa-
tion SBDD or THDD). Covers are made of grey
cast iron.

Paint, corrosion protection
SBD plummer block housings and THD take- Dimension standards
up housings are painted blue (RAL 5007) using The dimensions of SBD and THD housings are
a solvent based alkyd/acryl paint. The paint not standardized either nationally or
protects the housing in accordance with internationally.
ISO 12944-2, corrosivity category C2 (i.e.
exterior atmospheres with low level of pollu-
tion, interior atmospheres where condensa-
tion may occur). The paint is not affected by
most lubricating oils, cutting fluids or alkales-
cent washing chemicals. Housings can be
repainted with most water or solvent based 1-
or 2-component paints.
Unpainted surfaces are protected by a
solventless rust inhibitor.
