New seals for ECO Plus hub bearing system
In October 2004. BPW introduced the new ECO Seal hub Four-stage dust lip Dirt seal
bearing sealing system. Seal wear ring
With a larger dirt seal and new two stage dust seal, the
proven concept of the ECO Plus seal has clearly been
further improved in a number of areas.
For example, the primary sealing lip is no longer fitted Main sealing lip
directly against the hub bearing, but instead fits against
a special thrust race integrated into the seal assembly.
This new design enables the circumferential velocity of
the seal to be significantly reduced, and with that, the 6.5 - 9t version up to September 2004
amount of wear. In addition, the wheel bearing is provided Dust and dirt sealing lips Dirt seal*
with even better protection against dirt penetration by
means of the covering dust and dirt sealing lips.
The seal wear ring remains in the hub when changing
over to the new seal.
New ECO Plus bearings are supplied without a race.
