Anyone have any recommendations for cheap bearings that only have one rubber shield? I hate how Mini Logos are double shielded.
The first thing I do with any bearings that have shields on both sides is pop them both off to have a look and put only one back on the "front" to cover the ball bearings and away you go. That also means you have a spare set of shields in case some come off or whatever.
Has worked for me with this method with Mini Logo and a number of others over the years, especially when I need a set of shields to put back on bearings that people have brought back in, I have lots to choose from.
As to why or any differences, I would say almost always there are no differences between bearings with one shield and two. All of the Bones bearings (same as Mini Logo) can have shields fit on either side, but I think most do not, more as a cost saving measure than anything else.
The old Swiss Labyrinth bearings had two shields, but they were a special type of bearing and sometimes it actually causes issues, so those ones in particular would work best by taking both shields off. I guess that is why they were discontinued anyway.
But back to topic, you can just as easily take off one or both shields from any bearings and then put just one back on so they run as per usual, without any issues. If you do accidentally bend a shield when removing it, flattening it again with the end of a skate tool is easy enough too.
Hope this helps.
* Back when Mini Logo had metal on one side, they were a bit more of a pain, but I used to take those metal ones off too, just to have only one shield on the front. So glad they have two rubber shields on them now, as I get to keep a spare set from each pack. A post about it from a while back:
