Bearing shields seem to be missing from my wheel


Hi, guys,

So a while back, I noticed that one of my FlatFace G7.1D wheels appears to be missing a bearing shield (or maybe both shields on both sides, I’m not entirely sure.)

Is this a cause for concern for my wheel or the bearing? Should I use a spacer on the wheel axle just in case? Can the bearings be replaced? Any answers appreciated.

The wheel in question is first on the left in the attached images. Thanks.
