Bearing 6901Z with dimensions d24 – d12 – 6 (made in China). The Z suffix means a shield on one side. Suitable for assemblies that need a rotating shaft of small diameter.
Replace it if it hums and has play, if rotation has become uneven or jerking has appeared. Do not delay replacement: a destroyed bearing can damage the shaft and the housing. After installation, check that the shaft rotates without binding and without noticeable play.
