Ball Bearing Repair/Replacement

Both ball bearings are maintenance free. If the bearings are
removed, they must be replaced along with any seals.
If a bearing which is to be replaced has only one sealing lip,
this should be greased with quality bearing grease. After
approximately 10,000 operating hours the bearings have to be
replaced.
