Anet A8 Bearing shell / Lagerhülse

Hi.
After some research I found out that there are many diffrent opinions for the right replacement of the linear bearings.
I think I found out a good and also not so expencive way to get a good working bearing system.
I found some good Sinterbronze bearings on ebay
You will need Bearings like this: (8mm inner diameter x 12mm outer diameter x 20mm lenght)
