Dexter Axle offers several types of bearing arrangements and
lubrications 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.
Hub Removal - Standard Bearings
Whenever the hub equipment on your axle must be removed for
inspection or maintenance the following procedure should be
utilized.
1. Elevate and support the trailer unit per manufacturers’
instructions.
