If you use a bearing with seals either side, the seals can be prised off to clean out dried up/dirty grease and re-grease, they can then be pushed back in place.

The SKF handbook recommends that the bearing rotating ring should have a tight fit (to avoid 'creep' of the ring) - in the case of the Austin 7 hub, in the housing, while the bearing stationary ring may have a loose or sliding fit of the inner ring, in this case on the axle.
If the bearing is tight in the 'felt housing' -usually unlikely - then it is better to carefully press it out rather than drive it out and risk damaging the track.
