Bearings with a YSPAG designation prefix
(† fig. 1) are equipped with a new, patent-
ed seal consisting of a stamped steel insert
with a vulcanized five-lip seal made from
acrylonitrile-butadiene rubber. These new
seals are recommended for applications
where there is a high degree of contamina-
tion e.g. agricultural machinery. YSPAG
bearings are lubricated for the life of the
bearing.
SKF Energy Efficient bearings, designation
prefix E2 († fig. 2), are equipped with a
new low-friction contact seal. The new seal
is made from acrylonitrile-butadiene rubber
and reinforced with a pressed steel insert.
Plain sheet steel flingers on the outboard
side of the seal have an interference fit on
the inner ring to considerably enhance the
seals’ effectiveness without increasing
friction.
E2.YSP SB-2F bearings are filled with a
special low-noise, low-friction SKF grease.
