The NTE bearing catalogue lets you find a bearing by its designation or by its dimensions d, D and B and check its load ratings and mass. NTE offers ball, roller and spherical plain bearings, as well as bearing units, for shaft diameters from 3 to 260 mm.

Nothing found Type just the start of the designation, or change the size range.
How to read a bearing designation The bearing number gives the type and size; symbols before or after it describe seals, clearance and other features. Its last two digits are usually the bore code: from 04 up, multiply by 5, so a 6205 has a 25 mm bore. Codes 00, 01, 02 and 03 mean 10, 12, 15 and 17 mm.
