SKF has a long history in sealing knowledge. The demand for increased speeds, higher operating
temperatures and synthetic lubricants with aggressive additives
increase the stress on oil and grease seals. SKF seals deliver
unparalleled performance over a wide range of operating
conditions for most automotive and truck applications.
Our sealing products include conventional rubber shaft seals,
PTFE seals and low friction seals. All are made from the OE
specified or better materials for each application
Seal lip profile - All SKF seals incorporate a seal lip design that meets or exceeds
the OE specifications. This provides the toughest exclusion of dirt
and contaminants, reliable dynamic sealing and a long service life.
Sealing element - SKF’s synthetic rubber blends are formulated from families of
complex polymers to provide protection to operate in temperatures
as low as minus 40 degrees to as high as 400 degrees Fahrenheit.
Today’s lubricants with their aggressive additive packages can
attack the rubber compound of the seal. SKF seals are engineered
to be compatible with these lubricants.
Case - The case components are made from the highest grade of carbon
steel, and are coated with phosphate to ensure protection against
rust. Most metal-cased seals are coated with Bore-Tite, a flexible
coating on the outside diameter of the seal that fills in small housing bore imperfections, and provides a tight and leak proof seal.
