General

BPW hub bearings

H Conventional hub bearing system

Until introduction of the ECO hub system, BPW supplied
trailer axles with conventional hub bearings.
K In this hub bearing, the 2 sealing rings are mounted on

the stepped thrust washer (oil seals are used in the N..
axle series).
N A pulling device is required to pull off the complete hub
unit, the tapered inner roller bearing race as well as the
thrust washer and seal assembly.

ECO hub bearing system
Dismantling the patented BPW ECO hub system
(European patent 0 407 719 B1) couldn’t be simpler:
In only a few operations, the wheel (complete with the
hub, roller bearings and brake drum) is removed using
the central threaded connection – just like wheel changes
in motor racing.
The stepped bearing means there is no need to use a
puller or other special tools.
The roller bearings remain in the hub where they are well
protected against dirt and moisture.
Installation is also quick and easy: Box spanners are all
that are required for the hub cap and axle nuts.

ECO
If you expect high mileages, rapid servicing and low -10 / 2004
maintenance costs from your axles, then only ECO Plus
will do.
Ground-breaking ECO Plus bearing technology was
developed on the basis of the special BPW ECO hub
system.
The maintenance-free hub has an integrated multi-seal
system for protecting the tapered roller bearings against
dust and dirt.
A central threaded connection with integrated torque
limiting function ensures the bearing preload is always
optimum.
