Pre Lubricated Shielded Skateboard Bearings - 8x22x7 Size Review

The batch I received was machined perfectly to fit motor shafts. Replaced the original and saved $175. As they are suitable for many applications, it pays to have several spare parts on hand.

Used them on a whirligig and a bearing on my daughter's skateboard. Works great in both apps. Whirligig spin easily in light winds, so they have low friction. The skateboard rolls smoother and farther than before.

I didn't realize how versatile this little bearing was until I used it to fix my brother's wheels (fits perfectly). I was in the process of rebuilding a vacuum cleaner motor when my eldest son realized these bearings would work in the motor too. My brother runs much better and the vacuum cleaner sounds like a powerful vacuum cleaner! Needless to say how much money was saved! Very durable and well sealed.
