SKF inboard seal for hub bearingSKF claims it has introduced a new inboard seal for hub bearing units that can deliver a 50% cut in friction. The cassette seal accommodates current ABS encoders and features an external lip and an optimised labyrinth design that collects and redirects contamination flow away from a main radial lip, says the company.

With just one lip in contact, the configuration ensures minimum friction and maximum protection that is claimed not to degrade over time.
