Leslie Bearings

The Leslie lower bearing used to be NTN 6200-LB at least on many two-speed Leslie models. (McMasterCarr 5972K41 ?) (10 mm bore, 30 mm diameter, 9 mm thick, non-rubbing rubber seals).

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.
