Conventional Hubs
ConMet conventional hubs feature
precision-machined aluminum or
iron castings and are available in
steer, drive and trailer congurations.
Hubs are supplied with bearing cups
and studs installed. Bearing cones
and wheel seals are supplied by the
customer. Bearings must be adjusted
manually. See TMC RP618 for
specics of adjustment procedures.

PreSet®Hub Assemblies
ConMet PreSet hub assemblies
include precision-machined hubs,
premium seals, specially toleranced
roller bearings and unique precision-
machined bearing spacers. This
combination eliminates the need
to manually adjust wheel end play.
These components are delivered as
a complete assembly, reducing the
potential for premature failures due
to incorrect end play settings and/or
improper installation practices.

1. Introduction
ConMet offers three types of wheel
hubs:
-Conventional hubs with
manually-adjusted bearings
-PreSet hub assemblies with
pre-adjusted bearings
-PreSet Plus hub assemblies
with pre-adjusted bearings
and an integrated spindle nut
PreSet Plus®Hub
Assemblies
ConMet PreSet Plus hub assemblies
feature the same PreSet technology
and include the same precision-
machined hubs, premium seals
and specially toleranced roller
bearings. However, PreSet Plus hubs
incorporate the following:
-An integrated spindle nut
that eases installation and
disassembly and protects
components during wheel end
service
-An optimized spacer
-Standard magnetic ll plug
