Dexter offers several types of bearing arrangements and lubrication methods.
• Dexter’s standard wheel bearing configuration consists of opposed
tapered roller bearing cones and cups, fitted inside of a precision
machined cast hub. This method of using tapered roller bearings requires
that a minimal amount of axial end play be provided at assembly. This
end play is essential to the longevity of the bearings service life. This
design is typically lubricated with grease, packed into the bearings. Oil
lubrication is another method which is available in some of the larger
axle capacities.
• E-Z Lube
®
is another option chosen by some trailer manufacturers. If
your axle is equipped with the Dexter E-Z Lube
®
feature, the bearings can
be periodically lubricated without removing the hubs from the axle. This
feature consists of axle spindles that have been specially drilled and
assembled with grease fittings in their ends. When grease is pumped into
the fitting, it is channeled to the inner bearing and then flows back to the
outer bearing and eventually back out the grease cap hole.
• Nev-R-Lube
®
option is the latest innovation from Dexter. Nev-R-Lube
®
bearings are comprised of opposed tapered roller bearing cones sealed
inside of a precision ground, one piece double cup arrangement. These
bearings are designed with a small amount of axial end play. This end
play is essential to the longevity of the bearings service life. They are
lubricated, assembled and sealed at the factory. No further lubrication is
ever needed.
Before attempting any disassembly of your Dexter axle, make sure you read and
follow the instructions for the appropriate axle type.
