608-2RS Full Ceramic Sealed Skate Bearing 8x22x7 Miniature Bearings

Excellent

I have used these bearings for over a year. For indoor roller skating they have required virtually no maintenance. They are smooth and quiet though not as quiet as Bones Swiss hybrids. I have found that a pin drop of lubricant (Rem oil Nano oil Tuf-oil etc.) helps to reduce friction from side loads (lots of turning). There is a difference when side loads are applied....check spinning when wheels are vertical vs. horizontal. I believe this is a function of race design rather than wear. Except for price I have found no other issues with these bearings. I purchased the bearings over a six month period. I previously used Bones Swiss steel bearings with Speed cream lubricant and Bones Swiss hybrid ceramics (factory lubricated). The lack of maintenance easily puts these bearings above my other bearings. From testing I have found that ceramic bearings without shields require some maintenance and cleaning though not as much as regular bearings.

Using the full ceramic bearings with one sided seal for rollerblading. These bearings roll great and require very infrequent cleaning with no lubrication.I absolutely love them and would recommend them. Wish they could be priced less for full set instead of having to buy individual. [...]
