Don’t know if anyone needs or has replaced their wheels due to bearing failure. The bearings on my nobles buffer were shot so I looked into replacements. I could not find bearings only, you have to by the complete wheel at $25 or so each….I went to Ace” the helpful hardware place” and found bearings that fit perfect. The bearings were flanged on one side so I put 1 on the inner and 1 on the outer opening of each wheel, worked great and they cost $22 for the repair (4 bearings and washers). One drawback is , they are steal and may pose a rust issue, I will keep an eye on them and let you know how they hold up.
