 The Basic Bearing
Numbering System
Usually,
with all the bearings discussed so far, the last two digits of the base bearing
number indicate the diameter (size) of the bearing’s bore in millimeters. The
first four (4) must be memorized.
- 00 = 10mm
- 01 = 12mm
- 02 = 15mm
- 03 = 17mm

Bore Dimensions
|
When the last two digits of the
base bearing number are 04 or larger, simply multiply the double digit number by
five (5) and you have the bore size in millimeters, i.e., 04 = 20mm, 10 = 50mm,
and 24 = 120mm.
