+The Leslie
lower bearing used to
be NTN 6200-
LB at least on many two-speed Leslie models
(for example, 122, 142, 147, 251
) and possibly also on earlier single-speed equivalents
(for example, 21H, 22H, 44W, 45, 51
). It has 10 mm
bore, 30 mm
diameter, 9 mm
thick and non-rubbing rubber seals. The original bearing is no longer available from NTN.

+As replacements
, types 6200-Z or 6200-2Z (for example from SKF) will work, also on a Tallboy models (31A, 31H, 31W). The Z models have non-rubbing steel shields. Model 6200-2RS 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. Someone had also previously mentioned McMasterCarr 5972K41 as a working replacement, which is of type 6200-2RS
.
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

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.
