+The original bearing is no longer available from NTN. The replacement is NTN 6200-RZ, which has one rubber and one steel seal.

+As those bearings are difficult to find, the 6200-Z or 6200-2Z will work, also on a Tallboy Leslies (31A, 31H, 31W). The Z models have non-rubbing steel shields. Avoid 6200-2RS, as it has rubbing rubber seals, which sometimes causes too much friction, especially when a motor controller (to convert single speed Leslie to dual speed) is used
.
The lower rotor bearing should include a 5/16 washer in between the wooden rotor and the bearing.

The upper bearing used to be
''MRC 35FF'' (5 mm
bore, 19 mm
diameter, 6 mm
thick, two shields). SKF 635-2Z is equivalent. Again, you want to get one without rubbing seals!
On a [Leslie710], you can replace both bearings with ball bearings from FAG. Type 6200.2RSR. Ball bearings are standardized industry parts, so a second source type is no problem at all.
