I need a "Bearing Assembly" for roller brush 61445-1,I Have a GE 106575

Hello,I Have a GE 106575,and to make a long story short,I need the "Bearing Assembly" for the brush roller 61445-1. The roller brush is in perfect condition except for one of the "Bearing Assembly's". It is not practical or wise to replace the whole roller brush because of 1 removable part that went bad. That would be like throwing good money down the drain. I can assume the "Bearing Assembly's" on this roller brush will need replacing every so often.

So I need to know where I can purchase the "Bearing Assembly" for the brush roller 61445-1.

Thank You Very Much,EarlsOK
