# Bearing size chart

Dimensions of 72 deep groove ball bearings: the 60, 62, 63, 68 and 69 series from 10 to 60 mm bore and miniature bearings from 3 mm. For example, a 6205 is 25 × 52 × 15 mm. The last two digits give the bore: 00 = 10 mm, 01 = 12, 02 = 15, 03 = 17, and from 04 up multiply by 5.

## Reading a bearing number

- First digit 6: single-row deep groove ball bearing.
- Second digit: dimension series. 0 extra-light, 2 light, 3 medium, 8 and 9 thin-section.
- Last two digits: bore code. 00 = 10 mm, 01 = 12 mm, 02 = 15 mm, 03 = 17 mm, from 04 up multiply by 5. Below 10 mm bore the last digit is the bore (608 = 8 mm).
- Suffixes: ZZ / 2Z metal shields both sides; 2RS, 2RS1, 2RSH, 2RSR, DDU, LLU rubber seals both sides; C3 greater than normal internal clearance.
