What is a sealed bearing?
There is a lot of confusion about bearings. Not just the difference between ceramic and steel, but the design of the bearing in general. We will be posting several articles clearing up some common mistakes with regards to bearings.
Our VCRC Ceramic bearings use rubber seals which can easily be removed for servicing (greasing and if needed, cleaning) and reinstalled.
This is also true for steel bearings that use rubber seals. Don't think that just because they are "sealed" it means they don't need maintenance. Bearings are like chains, you need to keep them lubed and clean for them to last. A VCRC Ceramic bearing will last longer than steel when properly maintained as the parts don't wear as easily as steel, but the longevity has a lot to do with proper maintenance.
