Split plummer block housings SNLN 30 series

Relubrication from the side for housings
with V-ring seals
When relubricating bearings from the side in
housings with V-ring seals, mount an additional
V-ring inside the housing on the side where
grease is applied († fig. 14). This forces the
grease to travel through the bearing and exit
the housing on the opposite side.
SKF can supply an appropriate V-ring
together with a splash plate that fits in the
seal groove to cover a bit more than the top
half of the housing. The sets are identified by
the series designation ASNA followed by the
housing size identification and the suffix V,
e.g. ASNA 3024 V, and are available from size
3024 to 3032.
Grease escape holes
When four-lip seals (TSN .. L) or felt seals Table 10
(TSN .. C) are used, grease cannot escape Recommended dimensions for grease escape hole
via the seals. If relubrication is required, the
housing should have a grease escape hole.
SNLN 30 housings can be supplied with a
grease escape hole (designation suffix V).
A grease escape hole can be drilled into the
housing using the dimensions provided in
table 10.
