Costs and risks –
at a low level
SNL plummer block housings have
several advantages, such as the high
load carrying capacity and machining
quality as well as the wide variety of
sealing alternatives with the following
design and performance
characteristics.
Stiff design
The housing base is reinforced with ribs
and extra material surrounding the holes
for the attachment bolts in order to provide
improved seating on the base plate. The
attachment bolts can be preloaded to give
correct location and prevent deformation
of the housing base and bore.
Excellent heat conduction
The web (rib) reinforcement of the housing
base enlarges the contact area between
base and base plate and allows for an
improved heat flow from the bearing outer
ring to the base plate. The bearings will run
5 to 10 % cooler than in other housings.
Drilled and tapped hole with nipple
SNL housings have a drilled and tapped
hole as standard in the cap. The hole is
protected by a plastic plug. The nipple is
supplied, together with a nipple protecter,
with the housing (packed inside). If the
application is such that relubrication is
required it is only necessary to screw the
nipple into the hole and lubricant can be
supplied to one side of the bearing.
• Stiff design Insensitive to uncontrolled tightening of the
attachment bolts, low operating temperatures
• Excellent heat Low bearing temperatures, high speed operation
conduction
possible with oil lubrication, long relubrication
intervals, long service life, low lubricant consumption

• Drilled and tapped Relubrication facility as standard
hole with nipple
• Caps and bases Avoids mixing of caps and bases, permits traceability
individually marked
• Indications for holes to Simple and easy adaptation of standard housing to
take other components individual applications, easy attachment of condition
monitoring equipment
• Simple mounting Simple and reliable mounting and maintenance
• Additional seals Several sealing options, long bearing service lives
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 prevent mixing caps
and bases when mounting several housings,
the same consecutive number is
marked on the cap and base of each
individual housing.
