I needed new wheelbearings for the Wolseley Ten. I found them at a local shop. They even had an improved sealed version. I was told bearing technology has evolved. Better materials and production tolerances should make these new bearing last much longer.
See how there's a metal seal over the bearings. Rubber selas are available too, for waterproof bearings.
You can see the difference. Below the old bearing. You can see how the bearings are exposed. A felt seal tries to protect the bearings in the Wolseley.
