One basic design –
many variants
SNL plummer block housings are primarily
intended for self-aligning ball
bear-ings, spherical roller bearings and
CARB bearings. The housings are
designed on a “building block” principle.
This enables a more generous choice
of bearing, shaft mounting, seals and
type of lubrication. Stocking is also
simplified.
A building block system
The basis of the SNL plummer block
housing system consists of a number
of housings of the same design but in
different sizes. By combining these
housings with the different standard
seals a wide variety of housing variants,
all belonging to the standard range, can
be supplied to cover the majority of
demands for plummer blocks for shafts
having diameters of 20 to 160 mm,
inclusive. The standard range also
covers other variants, for example,
housings with drilled and tapped holes
for lubrication nipples or condition
monitoring sensors. Housings are also
available for bearings for larger shaft
diameters (➔ page 79).
SNL plummer block housings are
made of grey cast iron and demonstrate
high strength. Should, however,
this strength be inadequate, dimensionally
equivalent plummer block
housings of spheroidal graphite cast
iron can be supplied.
Several sealing options
An important advantage of the SNL
plummer block housings is that they
can be fitted with a variety of seals.
The standard seals supplied by SKF
comprise double-lip seals, V-ring
seals, felt seals, labyrinth seals and
heavy-duty “taconite” seals as well as
end covers. Other standard seals are
also available for SNL housings, but
these are supplied together with the
housings as the housing has to be
modified to take them. These are oil
seals and heavy-duty axial taconite
seals.
SNL plummer block housings are
fully interchangeable with the earlier
SNH housings. Their dimensions
conform to ISO 113:1994.
Painting system
SNL plummer block housings are
painted as standard in accordance
with ISO 12944-2, environmental
Class C2. Black colour: RAL 9005.
