I am replacing bearings on an old Craftsman 1/2 HP motor for a drill press. The original bearings were single row, single shielded, single seal bearings with an extended inner race holding a felt seal.
Is there any reason not to replace with deep groove, double shielded bearings? My reasoning is that the shielded bearings would be sealed better and that the old bearings were just open for greasing (or were cheaper).
The width of the double shielded bearings is 11 mm, whereas the original bearings were 11 mm + about 0.070" where the extended race was. I guess my concern is that there might be a problem due to the narrower width on both ends on the motor.
My old bearings are New Departure 8502 / Accurate 87502. My proposed replacements are Nachi 6202ZE.
Input welcomed - I don't deal with bearings often.
