This is a double row bearing, which means it has 2 rows of balls instead of the usual 1, which gives it a higher load rating. Normally used where a shaft is supported by a single bearing.
Same as 3202 bearing except for radius on edge of bearing.
Recovered 8 BONA BELT 8 drum. This is not an older Bona prosand drum!This drum has been tapered (football shaped) to assist in tracking and reduction of edge cutting. Precision balanced to similar specs as all our belt sander drums.
