Radial Arm Saw Carriage Bearing 63350

Quality is disappointing

The construction is different from the original bearings. The outer grooved part of the original was part of the bearing. The new one has a replaceable bearing assembly separate from the grooved outer part. This is good since I may need to replace the bearing again since it is an unsealed bearing. I mean who in there right mind would put an unsealed bearing in an exposed area on a machine that makes dust.
