The Explosion-proof housing is designed for use in
environments classified as hazardous. The housing is
manufactured of aluminum alloy with a copper content less
than 0.3% maximum. On three sides the bosses are drilled
and tapped for 3/4 inch (19 mm) NPT conduit fittings. The
dome type housing is specified requiring a minimum of
floor space for fixture mounting. Two sizes are available
which should normally meet criteria for an explosion-proof
housing at each bearing or a larger size where the drivers
from multiple bearings can be housed.
